Description
[ technical field ] A method for producing a semiconductor device
The invention relates to the technical field of broadband terminal equipment networking, in particular to a three-four address router and a method and a device for managing an under-hanging device thereof.
[ background of the invention ]
According to the traditional scene, a main gateway/main route directly hangs down devices such as a mobile phone, a computer and a set top box, the devices use physical addresses when acquiring IP addresses, information interaction captured by a wireless module, a protocol module and a driving module uniquely identifies one device by the physical addresses, and a management module can manage the devices in a unified mode.
With the occurrence of networking requirements, routers serve as network nodes, and by using a Wireless Distribution System (WDS) technology, the traditional wired network can be abandoned among the routers for interconnection, so that a complete networking scene is formed with a main gateway, and the main gateway needs to manage all devices including the routers and the devices under the routers. For the implementation of WDS, there is no explicit provision in the protocol, but in the header of the wireless data frame, an address location is reserved. Therefore, all wireless data frames have four address fields, only the first three fields are used, which is called three addresses, and the four fields are called four addresses, and currently, three addresses or four addresses are used in the industry as wireless link data frame encapsulation modes. Three data necessary for wireless data Transmission are DA (Destination Address), SA (Source Address), BSSID (Basic Service Set Identifier), and the three addresses only use the first three fields to store information, so that a physical Address cannot be stored, while DA, SA, RA (Receiver Address) and TA (Transmission Address) can be stored simultaneously by adopting a four-Address wireless link data frame encapsulation method.
Assume a networking environment as follows: the main gateway, the sub-router and the down-hanging device are connected in series, and the three/four addresses are target addresses stored in DA during communication.
For a three address router (i.e., a child router): the message sent by the drop device originally stores the physical address of the drop device in the SA, the BSSID stores the wireless address of the three-address router, but after the message passes through the three-address router, the SA is changed into the wireless address of the three-address router, and the BSSID stores the wireless address of the main gateway, so that the loss of the physical address of the drop device is caused. The MAC message received by the main gateway is carried as a wireless address of the sub-router and an access port of the sub-router, the address resolution protocol message interaction message carries the wireless address of the sub-router and an IP address acquired by the sub-router or the lower hanging device thereof, the configuration protocol message is not influenced by a networking mode, and the interaction message carries the physical address of the router or the lower hanging device thereof and the IP address acquired by the router or the lower hanging device thereof.
For a four address router (i.e., a child router); the message sent by the drop device stores the physical address of the drop device in the SA, the BSSID stores the wireless address of the four-address router, after the message passes through the four-address router, the SA is kept unchanged, the RA stores the wireless address of the four-address router, the TA stores the wireless address of the main gateway, and the physical address of the drop device is not lost. The MAC message received by the main gateway is carried as a wireless address of the sub-router and an access port of the sub-router, the ARP message interaction message carries a physical address of the sub-router or the equipment hung below the sub-router and an IP address acquired by the sub-router or the equipment hung below the sub-router, the configuration protocol message is not influenced by a networking mode, and the interaction message carries a physical address of the router or the equipment hung below the router and an IP address acquired by the router or the equipment hung below the router.
In view of the above, overcoming the drawbacks of the prior art is an urgent problem in the art.

In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Example 1:
A wireless module: when a sub-router (a drop device without the sub-router, because an actual access point of the drop device of the sub-router is the sub-router and not a main gateway, the main gateway cannot receive a MAC message when the drop device of the sub-router accesses the sub-router) accesses the main gateway, a wireless module of the main gateway can acquire a MAC address (where the MAC address is a wireless address) of the sub-router and an access port where the sub-router accesses the main gateway, and report the MAC address of the sub-router and the access port where the sub-router accesses the main gateway to an event alarm module, and the event alarm module uniformly packages information and reports the information to a management module in the form of a MAC message, that is, the MAC message includes the wireless address of the sub-router and the access port where the sub-router accesses the main gateway.
A protocol module: when the sub-router or the drop device of the sub-router accesses the system and then acquires the dynamic IP address, the protocol module may acquire the MAC address (where the MAC address is a physical address) and the IP address of the sub-router or the drop device of the sub-router, and report the MAC address and the IP address of the sub-router or the drop device of the sub-router to the event warning module, and the event warning module packages information in a unified manner and reports the information to the management module in a form of a configuration protocol message, that is, the configuration protocol message includes the physical address and the IP address of the sub-router or the drop device of the sub-router.
A driving module: when data interaction is generated after the sub-router or the drop device of the sub-router is accessed, for the three-address router, the driving module can acquire the MAC address (where the MAC address is a wireless address) and the IP address of the sub-router or the drop device of the sub-router, where the wireless addresses of the sub-router or the drop device of the sub-router are the same (the sub-router itself has two addresses, one is a physical address and one is a wireless address, both of which are MAC addresses, when the sub-router itself interacts with the main gateway, the wireless address is used, after an interaction message with the main gateway sent by the drop device of the sub-router passes through the sub-router, the physical address of the drop device of the sub-router is uniformly converted into the wireless address of the sub-router by the sub-router, so that the wireless address of the sub-router is used when the drop device of the sub-router or the sub-router interacts with the main gateway information, in this embodiment, the wireless address of the drop device of the sub-router is the wireless address of the sub-router), the driving module reports the wireless address and the IP address of the sub-router or the drop device of the sub-router to the event alarm module, the event alarm module packages the information in a unified manner and reports the information to the management module in the form of an address resolution protocol message, that is, for the three-address router, the address resolution protocol message includes the wireless address and the IP address of the drop device of the sub-router or the sub-router, and when the sub-router accesses the system, the driving module generates a bridge address table including the wireless address of the sub-router and the access port of the sub-router accessing the main gateway (for the three-address router, as described by way of example in the background art, since the message received by the main gateway only includes the wireless address of the sub-router and does not include the physical address of the drop device, so the drive module cannot acquire the physical address of the drop device to generate the network bridge address table).
For a four-address router, the driver module may obtain a MAC address (where the MAC address is a physical address) and an IP address of a sub-router or a drop-off device of the sub-router, and the event alarm module uniformly packages information and reports the information to the management module in the form of an address resolution protocol message, that is, for the four-address router, the address resolution protocol message includes the physical address and the IP address of the sub-router or the drop-off device of the sub-router, and when the sub-router or the drop-off device of the sub-router accesses the system, the driver module may generate a bridge address table including the physical address of the sub-router or the drop-off device of the sub-router and a bridge address table of an access port of the sub-router accessing the main gateway (for the four-address router, as described in the example in the background art, a message received by the main gateway includes a wireless address of the sub-router and includes the physical address of the drop-off device, so the drive module can acquire the physical address of the drop device to generate the network bridge address table).
An event warning module: and the management module is responsible for uniformly packaging information, packaging corresponding message formats and forwarding the corresponding messages to the management module.
A management module: the system is in charge of gathering messages of the sub-routers and the hanging-down devices of the sub-routers, identifying and recording the information of the sub-routers or the hanging-down devices of the sub-routers after information matching, and for the unique identification of the sub-routers or the hanging-down devices of the sub-routers, the unique identification can be carried out on the devices only after the unique identification information formed by the physical addresses, the IP addresses and the access ports of the sub-routers or the hanging-down devices of the sub-routers is obtained.
The embodiment provides a three-four address router and a method for managing an under-hanging device thereof, which comprises a plurality of items in a configuration protocol message, a network address table, an MAC table and a bridge address table, wherein the configuration protocol message comprises an MAC address and an IP address;
matching the same MAC address in a bridge address table by using the MAC address of the configuration protocol message, if the same MAC address is not matched in the bridge address table according to the MAC address of the configuration protocol message, indicating that the equipment sending the configuration protocol message is a three-address router or a drop-on equipment of the three-address router, if the same MAC address is matched in the bridge address table according to the MAC address of the configuration protocol message, indicating that the equipment sending the configuration protocol message is a four-address router or a drop-on equipment of the four-address router, acquiring an access port in a row record corresponding to the MAC address in the matched bridge address table, and identifying the equipment according to the MAC address of the configuration protocol message, the IP address of the configuration protocol message and the matched access port in the bridge address table because the MAC address of the configuration protocol message is a physical address, the embodiment provides a mode that can be implemented in an actual scenario, and specifically includes:
assuming that the MAC address and the IP address included in the configuration protocol message obtained by the management module are 54: f2:94:1b:93:22 and 192.168.1.11, respectively, where the MAC address included in the configuration protocol message is a physical address, the same MAC address is matched from the bridge address table according to the MAC address 54: f2:94:1b:93:22 in the configuration protocol message, assuming that the bridge address table contains a row record of "54: f2:94:1b:93:22, PORT 1", the same MAC address as 54: f2:94:1b:93:22 can be matched in the bridge address table, and then the PORT1 (i.e. the MAC address included in the row record of "54: f2:94:1b:93:22, PORT 1" is fetched, and since the MAC address included in the configuration protocol message is a physical address, the MAC address 54: f2: 1b:93:22 in the configuration protocol message can be fetched, The IP address 192.168.1.11 of the configuration protocol message and the access PORT1 matched in the bridge address table are used as the device identification information to identify the device. And if the same MAC address is not matched in the bridge address table according to the configuration protocol message, the configuration protocol message is sent by the three-address router or the drop device of the three-address router.
As shown in fig. 2 and fig. 3, the network address table is generated by a configuration protocol message and an address resolution protocol message, the configuration protocol message includes a MAC address and an IP address, where the MAC address included in the configuration protocol message is a physical address, and the address resolution protocol message includes: and a MAC address and an IP address, wherein the MAC address in the address resolution protocol message is a wireless address for the three-address router or the off-hook device of the three-address router, and the MAC address in the address resolution protocol message is a physical address for the four-address router or the off-hook device of the four-address router, so that the network address table generated by the configuration protocol message and the address resolution protocol message includes the IP address and two MAC addresses (the physical address and the wireless address) for the three-address router or the off-hook device of the three-address router. For a four address router or a four address router's off-hook device, the network address table contains only IP addresses and one MAC address (physical address).
The MAC table is generated from MAC messages, and since the MAC messages contain the MAC addresses (wireless addresses) and access ports of the sub-routers, the MAC addresses (wireless addresses) and access ports of the sub-routers are also contained in the MAC table.
When a three-address router (i.e., a sub-router) accesses a main gateway or a main router, this embodiment takes accessing the main gateway as an example, and generates a bridge address table including a MAC address (wireless address) of the sub-router and a sub-router access port, and when a four-address router (i.e., a sub-router) or a drop-off device of the four-address router accesses a network, generates a MAC address (physical address) of the drop-off device of the sub-router or the sub-router and a bridge address table including the sub-router access port, where the access ports related to this embodiment are all access ports when the sub-router accesses the main gateway, and the physical addresses related to this embodiment are all physical addresses of the drop-off device of the sub-router or the sub-router.
When a management module receives a message of a router or a down-hanging device of the router, firstly, the type of the received message is judged, and the message types are generally divided into three types: the method comprises the steps of configuring protocol messages, address resolution protocol messages and MAC messages, wherein a certain time delay exists between the factor router or the lower-hanging device of the sub-router to acquire addresses and information interaction, the management module receives three messages without a fixed sequence, the management module initiates a round of information matching when receiving any message, IP addresses related to the embodiment are all IP addresses of the lower-hanging device of the sub-router or the sub-router, and the three-address router and the four-address router are all sub-routers. The device is identified based on a plurality of physical addresses, IP addresses, and access ports.
As shown in fig. 4, step 10, acquiring a configuration protocol message, and if the same MAC address is not matched in a bridge address table according to the configuration protocol message, matching different MAC addresses in a network address table according to an IP address of the configuration protocol message;
configuration protocol message initiated matching: the method comprises the steps that a management module acquires a configuration protocol message, wherein the configuration protocol message comprises an MAC address and an IP address, the MAC address of the configuration protocol message is a physical address, the MAC address in a bridge address table is matched according to the MAC address in the configuration protocol message (namely whether a row record corresponding to the MAC address which is the same as the MAC address in the configuration protocol message is contained in the bridge address table or not is judged), and if the same MAC address is matched in the bridge address table according to the configuration protocol message (the configuration protocol message is sent by a four-address router or a drop device of the four-address router), an access port in the row record corresponding to the MAC address in the matched bridge address table is acquired so as to acquire the physical address, the IP address and the access port to identify the device;
the embodiment provides a mode that can be realized in an actual scene, specifically:
assuming that the MAC address and the IP address contained in the configuration protocol message are 54: f2:94:1b:93:22 and 192.168.1.11, respectively, the management module matches the same MAC address from the bridge address table according to the MAC address 54: f2:94:1b:93:22 in the configuration protocol message, assuming that the bridge address table contains a line record of "54: f2:94:1b:93:22, PORT 1", the bridge address table can be matched with the same MAC address 54: f2:94:1b:93:22 as the MAC address in the line record of the configuration protocol message, and then the line record of "54: f2:94:1b:93:22, PORT 1" (access PORT), the MAC address contained in the configuration protocol message is a physical address, so that the MAC address 54: f2:94:1b:93:22, the corresponding address of the configuration protocol message and the line record of the IP address in the configuration protocol message are matched with the line record of the PORT1 (i. 1 2) in the network bridge address table, and the IP address of the PORT 1.192.11 in the network bridge address record of the configuration protocol message And the identification information is used for identifying the equipment. If the same MAC address is not matched in the bridge address table according to the configuration protocol message, namely, if the line record with the same MAC address cannot be matched in the bridge address table according to the MAC address 54: f2:94:1b:93:22 in the configuration protocol message (at this time, the configuration protocol message is sent by a three-address router or a lower hanging device of the three-address router), judging whether the IP address according to the configuration protocol message is matched with a different MAC address in the network address table; firstly, whether the current network address table contains the same row record as the IP address 192.168.1.11 of the configuration protocol message is judged according to the IP address 192.168.1.11 of the configuration protocol message.
specifically, whether a row record which is the same as the IP address of the configuration protocol message is contained in a current network address table is judged according to the IP address 192.168.1.11 of the configuration protocol message; assuming that the network address table contains a row record of "54: F2:94:1B:93:32, 192.168.1.11", a row record of the same IP address 192.168.1.11 of the configuration protocol message may be matched in the network address table, and then it is determined whether the MAC address 54: F2:94:1B 93:22 of the configuration protocol message is the same as the MAC address in the matched row record of "54: F2:94:1B:93:32, 192.168.1.11", since the MAC address in the row record of "54: F2:94:1B:93:32, 192.168.1.11" is 54: F64: 94:1B:93:32, which is different from the MAC address 54: 483f 5: 94:1B:93:22 of the configuration protocol message, the row record of the MAC address 54: F2:94:1B:93:22 of the configuration protocol message is updated 3693: 94: 93:22, the row record of the MAC address 54: F2:94: 1: 93: 1B:93:22 of the configuration protocol message is updated 3693: 93: 78, and the new row record of the IP address of the row record of the configuration protocol message is updated 3693: 1.168.1.1.11.1.11.1.11.11.3: 94: 93: 3: 94: 93: 3: 94: 93: 1.1.11 of the configuration protocol message, 54: f2:94:1b 93:22 and 192.168.1.11.
Since the MAC address matched in the network address table according to the IP address 192.168.1.11 of the configuration protocol message is 54: F2:94:1B:93:32 different from the MAC address 54: F2:94:1B:93:22 of the configuration protocol message, the same MAC address is matched in the MAC table according to the MAC address 54: F2:94:1B:93:32, namely the corresponding access port is found.
and step 40, if different MAC addresses matched in the network address table according to the IP address of the configuration protocol message are matched to the same MAC address in the MAC table, acquiring an access port corresponding to the same MAC address matched in the MAC table so as to identify the equipment.
Assuming that the current MAC table contains a record of "54: F2:94:1B:93:32, PORT 1", the different MAC addresses 54: F2:94:1B:93:32 matched in the network address table according to the IP address of the configuration protocol message may be matched to the row record "54: F2:94:1B:93:32, PORT 1" corresponding to the same MAC address in the MAC table, and then the PORT1 (i.e. access PORT) in the row record of "54: F2:94:1B:93:32, PORT 1" is taken out, where the different MAC addresses matched in the network address table according to the IP address of the configuration protocol message are wireless addresses, and the IP address 54: F2:94:1B:93:22 of the configuration protocol message, the IP address 192.168.1.11 of the configuration protocol message, and the PORT1 taken out from the MAC table are used as identification device information.
And step 50, if the different MAC addresses matched in the network address table according to the IP address of the configuration protocol message are not matched with the same MAC address in the MAC table, waiting for updating the MAC table.
As shown in fig. 5, if the same MAC address is matched in the bridge address table according to the configuration protocol message, the method specifically includes: the network bridge address table comprises MAC addresses and access ports, wherein the MAC addresses in the network bridge address table comprise wireless addresses and physical addresses;
the management module acquires a configuration protocol message, wherein the configuration protocol message comprises an MAC address and an IP address, the MAC address of the configuration protocol message is a physical address, and the MAC address in the network bridge address table is matched according to the MAC address in the configuration protocol message (namely, whether a row record corresponding to the MAC address which is the same as the MAC address in the configuration protocol message is contained in the network bridge address table or not is judged).
Assuming that the MAC address and the IP address included in the configuration protocol message obtained by the management module are 54: f2:94:1b:93:22 and 192.168.1.11, respectively, where the MAC address of the configuration protocol message is a physical address, matching the same MAC address from the bridge address table according to the MAC address 54: f2:94:1b:93:22 in the configuration protocol message, assuming that the bridge address table contains a row record of "54: f2:94:1b:93:22, PORT 1", matching the same MAC address as the MAC address 54: f2:94:1b:93:22 of the configuration protocol message in the bridge address table, and then fetching the row record of "54: f2:94:1b:93:22, PORT 1" (i.e., accessing PORT), since the MAC address included in the configuration protocol message is a physical address, the MAC address 54: f2:94:1b:93:22 and the IP address of the configuration protocol message is 54: 93: 78: 93: 1b: 78: 22, The IP address 192.168.1.11 of the configuration protocol message and the access PORT PORT1 in the row record corresponding to the matched MAC address in the bridge address table are used as the equipment identification information to identify the equipment.
As shown in fig. 6, the matching of different MAC addresses in a network address table according to the IP address of the configuration protocol message specifically includes:
if the same MAC address is not matched in the bridge address table according to the configuration protocol message (at this time, the configuration protocol message is sent by a three-address router or a drop device of the three-address router), different MAC addresses are matched in the network address table according to the IP address of the configuration protocol message, and whether the current network address table contains the row record which is the same as the IP address of the configuration protocol message is judged according to the IP address of the configuration protocol message. Assuming that the MAC address and the IP address included in the configuration protocol message obtained by the management module are 54: f2:94:1b:93:22 and 192.168.1.11, it is first determined whether the current network address table contains the same row record as the IP address 192.168.1.11 of the configuration protocol message according to the IP address 192.168.1.11 of the configuration protocol message.
and if the current network address table does not contain the row record which is the same as the IP address of the configuration protocol message, storing the MAC address and the IP address in the configuration protocol message into the network address table, waiting for the initiation of the address resolution protocol message to match and updating the network address table.
Assuming that the network address table contains a row record of "54: F2:94:1B:93:32, 192.168.1.11", the same row record of "54: F2:94:1B:93:32, 192.168.1.11" as the IP address of 192.168.1.11 of the configuration protocol message may be matched in the network address table, and then it is determined whether the MAC address of the configuration protocol message 54: F2:94:1B:93:22 is the same as the MAC address of the matched row record of "54: F2:94:1B:93:32, 192.168.1.11".
And 204, if the IP addresses are different, matching different MAC addresses in a network address table according to the IP address of the configuration protocol message.
Since the MAC address in the record of the line "54: F2:94:1B:93:32, 192.168.1.11" is 54: F2:94:1B:93:32, which is different from the MAC address 54: F2:94:1B:93:22 of the configuration protocol message, it indicates that a different MAC address is matched in the network address table according to the IP address of the configuration protocol message.
As shown in fig. 7, an address resolution protocol message is further included, wherein the address resolution protocol message includes a MAC address and an IP address.
matching initiated by address resolution protocol messages: the management module acquires an address resolution protocol message, wherein the address resolution protocol message comprises a MAC address and an IP address, the MAC address in the address resolution protocol message is a wireless address, and the MAC address and the IP address in the acquired address resolution protocol message are respectively 54: F2:94:1B:93:32 and 192.168.1.11.
judging whether a current network address table contains row records which are the same as the IP address of the address resolution protocol message or not according to the IP address of the address resolution protocol message, if so, judging whether the current network address table contains the row records which are the same as the IP address of the address resolution protocol message or not according to the IP address 192.168.1.11 of the address resolution protocol message, and if not, storing the address resolution protocol message into the current network address table. Assuming that the network address table contains a row record of "54: f2:94:1b:93:22, 192.168.1.11", the same row record of "54: f2:94:1b:93:22, 192.168.1.11" as the IP address of the address resolution protocol message 192.168.1.11 can be matched in the network address table.
specifically, the IP address 192.168.1.11 in the address resolution protocol message is matched from the network address table, and if the network address table contains a row record of "54: F2:94:1B:93:22, 192.168.1.11", a row record of "54: F2:94:1B:93:22, 192.168.1.11" identical to the IP address 192.168.1.11 in the address resolution protocol message may be matched in the network address table, and then it is determined whether the MAC address 54: F2:94:1B:93:32 of the address resolution protocol message is identical to the MAC address in the matched row record of "54: F2:94:1B:93:22, 192.168.1.11", that is, it is determined whether the corresponding physical address is already stored in the network address table.
since the row of the same IP address that is matched from the network address table according to the IP address 192.168.1.11 in the address resolution protocol message is recorded as "54: f2:94:1b:93:22, 192.168.1.11", the MAC address in this row record is 54: f2:94:1b:93:22, its MAC address 54 with the address resolution protocol message: f2:94:1B:93:32 are different, indicating that the corresponding physical entity has been stored in the network address table, line record "54: f2:94:1b: MAC address 54 in 93:22, 192.168.1.11 ": f2:94:1b:93:22 is a physical address, and the MAC address 54 in the address resolution protocol message is: f2:94:1B:93:32 to "54: f2:94:1b:93:22, 192.168.1.11', the updated network address table contains 54: f2:94:1B:93:32, 54: f2:94:1b:93:22 and 192.168.1.11.
Assuming that the current MAC table contains a record of "54: F2:94:1B:93:32, PORT 1", the same MAC address may be matched in the MAC table according to the MAC address 54: F2:94:1B:93:32 of the address resolution protocol message, the PORT1 (i.e., access PORT) in the record of "54: F2:94:1B:93:32, PORT 1" may be taken out after matching, the MAC address (physical address) 54: F2:94:1B:93:22, IP address 192.168.1.11 in the row record corresponding to the different MAC address matched according to the IP address of the address resolution protocol message and the PORT1 taken out from the MAC table may be used as the device identification information, step 308, and if the same MAC address is not matched in the MAC table according to the MAC address of the address resolution protocol message, the update of the MAC table may be waited.
Specifically, assuming that the MAC address and the IP address included in the address resolution protocol message obtained by the management module are 54: F2:94:1B:93:32 and 192.168.1.11, respectively, and the IP address 192.168.1.11 in the address resolution protocol is matched from the network address table, and the row record the same as the row record of the IP address 192.168.1.11 in the address resolution protocol cannot be matched, the address resolution protocol message is stored in the current network address table.
As shown in fig. 8, further comprising a MAC message, wherein the MAC message comprises a MAC address and an access port:
MAC message initiated matching: the management module acquires a MAC message, wherein the MAC message comprises a MAC address and an access PORT, the MAC address contained in the MAC message is a wireless address, the MAC message comprises the MAC address and the access PORT is updated into a MAC table, and the MAC address 54: F2:94:1B:93:32 and the access PORT PORT1 are updated into the MAC table on the assumption that the MAC address and the access PORT in the acquired MAC message are 54: F2:94:1B:93:32 and PORT1 respectively.
Assuming that the MAC address and the access PORT contained in the obtained MAC message are 54: F2:94:1B:93:32 and PORT1, respectively (the MAC address contained in the MAC message is a wireless address), and the current network address table contains a line record of "54: F2:94:1B:93:32, 54: F2:94:1B:93:22, 192.168.1.11" (that is, both the address resolution protocol message and the configuration protocol message corresponding to the device sending the MAC message are stored in the network address table), it can be determined that the current network address table contains the same line record as the MAC address 54: F2:94:1B:93:32 of the MAC message.
If the current network address table contains the row record which is the same as the MAC address of the MAC message, whether the row record which is the same as the MAC address of the MAC message in the current network address table contains the MAC address which is different from the MAC address of the MAC message or not is judged (namely, the corresponding physical address is inquired according to the wireless address contained in the MAC message), and if the row record contains the MAC address, equipment is identified.
Judging that the current network address table contains the MAC address 54 corresponding to the MAC message: f2:94:1B: after the recording of the same row 93:32, determine the row record "54 in the current network address table: f2:94:1B:93:32, 54: f2:94:1b:93:22, 192.168.1.11 "with the MAC address 54 of the MAC message: f2:94:1B:93:32 different MAC addresses of the MAC address, it can be seen that "54: f2:94:1B:93:32, 54: f2:94:1b:93:22, 192.168.1.11 "also contains MAC address 54: f2:94:1b:93:22, the MAC address 54: f2:94:1b:93:22 and MAC address 54 of the MAC message: f2:94:1B: the ratio of the weight of the rollers 93 to 32 is not the same, the MAC address 54 can be considered: f2:94:1b: the physical address of the address 93:22, then 54: f2:94:1b:93:22, 192.168.1.11 and PORT1 as device identification information. The above description is the complete process of the management method for the three-four address router and the off-hook device thereof provided by the embodiment of the present invention. This embodiment is merely an example and is not intended to limit the present invention.
Example 2:
the embodiment also provides an embodiment of a three-four address router and a method for managing the under-hung device thereof, which specifically comprises the following steps:
as shown in fig. 15, assuming that three devices, namely, a three-address router, a mobile phone 1 and a mobile phone 2, are sequentially connected to a main gateway to form a three-address networking mode, the most common message sequence is taken as an example in this embodiment, that is, a management module sequentially receives an MAC message, a configuration protocol message and an address resolution protocol message, and then identifies the three devices according to the received three messages.
(1-1) as shown in fig. 9, a three-address router is accessed to a master gateway:
when the three-address router accesses the main gateway, a network bridge address table containing the MAC address of the three-address router (the MAC address is the wireless address of the three-address router) and the access port accessing the main gateway is generated.
The management module acquires the MAC message, the MAC message carries the MAC address 1A1B1C1D and the access PORT PORT1, wherein, the MAC message carries the MAC address as the wireless address, and then the MAC message is updated into the MAC table, the embodiment assumes to be updated into the row record 1 of the MAC table, judging whether the current network address table contains the same row record as the MAC address 1A1B1C1D of the MAC message according to the MAC address 1A1B1C1D of the MAC message, since the management module is assumed to receive the MAC message first in this embodiment, the current network address table has not stored the arp message sent by the three-address router, therefore, the same row record as the MAC address 1A1B1C1D of the MAC message cannot be found in the network address table, and at this time, the address resolution protocol message and/or the configuration protocol message sent by the three-address router are waited to initiate matching and update the network address table.
(Note: MAC addresses 1A1B1C1D, 1A1B1C1d, etc. in this embodiment are for convenience of illustration and example)
The management module acquires a configuration protocol message, wherein the configuration protocol message carries a MAC address 1a1b1c1d and an IP address 192.168.1.1, the configuration protocol message carries a MAC address as a physical address, the MAC address 1a1b1c1d in the configuration protocol message is matched with the MAC address in the bridge address table (namely, whether a row record corresponding to the MAC address same as the MAC address in the configuration protocol message is contained in the bridge address table is judged), if the MAC address 1a1b1c1d in the configuration protocol message matches the same MAC address in the bridge address table, (indicating that the configuration protocol message is sent by a four-address router or a four-address router, if the MAC address 1a1b1c1d in the configuration protocol message does not match the same MAC address in the bridge address table, the configuration protocol message does not match the same MAC address in the bridge address table (indicating that the row record of the configuration protocol message is matched by the three-address router or the three-address router at this time) (indicating that the same MAC address cannot be matched by the MAC address in the configuration protocol message) That is sent by the drop device of the three address router), since the access is assumed to be the three address router in this embodiment, the MAC address 1a1b1c1d according to the configuration protocol message cannot be matched with the same MAC address in the bridge address table. At this time, it is determined whether the current network address table contains the row record that is the same as the IP address 192.168.1.1 of the configuration protocol message according to the IP address 192.168.1.1 of the configuration protocol message, because this embodiment assumes that the management module receives the configuration protocol message first, and therefore the management module has not received the address resolution protocol message sent by the three-place router, then the same IP address cannot be found in the network address table according to the IP address 192.168.1.1 of the configuration protocol message, at this time, the MAC address 1a1b1c1d and the IP address 192.168.1.1 of the configuration protocol message are stored in the current network address table, and it is assumed that the MAC address 1a1b1c1d and the IP address 192.168.1.1 of the configuration protocol message have been stored in the row record 1 of the network address table.
The method comprises the steps that a management module obtains an address resolution protocol message, wherein the address resolution protocol message carries an MAC address 1A1B1C1D and an IP address 192.168.1.1, and whether a current network address table contains a row record which is the same as the IP address of the address resolution protocol message or not is judged according to the IP address in the address resolution protocol message; since the management module has received the configuration protocol message sent by the three-address router and has stored the MAC address 1A1B1C1d and the IP address 192.168.1.1 of the configuration protocol message in the row record 1 of the network address table, it can match the same IP address in the network address table according to the IP address 192.168.1.1 in the address resolution protocol message, at this time, it is determined whether the MAC address 1A1B1C1D of the address resolution protocol message is the same as the MAC address corresponding to the row record in the network address table that is the same as the IP address of the address resolution protocol message, since the row record that is matched to the same IP address in the network address table according to the IP address 192.168.1.1.1 is "1 A1B1C1d, 192.168.1.1", it can be known that the MAC address corresponding to the matched row record is 1A1B1C1d, which is not the same as the MAC address A1B1C1 of the address resolution protocol message D, because the wireless address D is carried by the wireless address, then the physical address of the MAC address 1A1B1C1d, 192.168.1.1 in the row record "1 A1B1C1 d" in the row record "1B 1C1d, 192.168.1.1", the MAC address 1A1B1C1D in the address resolution protocol message is updated to the row record "1 A1C 1d, 192.168.1.1" corresponding to the different MAC addresses matched in the network address table, i.e. the row record 1 of the network address table, (if the row record of the same IP address is matched in the network address table according to the IP address 192.168.1.1 in the address resolution protocol message, and the MAC address of the address resolution protocol message is not the same as the MAC address corresponding to the row record of the same IP address in the network address table, then the drop device that sent the address resolution protocol message is a three-address router or a three-address router, but not a four-address router, and the MAC address of the address resolution protocol message is the same as the row record in the network address table The address is a physical address, i.e., 1a1b1c1d is a physical address). After updating the MAC address 1A1B1C1D in the address resolution protocol message to the row record 1 of the row record "1 A1B1C1d, 192.168.1.1" corresponding to the different MAC addresses matched in the network address table, the row record 1 of the network address table contains 1A1B1C1D, 1A1B1C1d and 192.168.1.1.
And finally, matching the same MAC address in the MAC table by using the MAC address of the message of the address resolution protocol, and if the same MAC address is matched, acquiring an access port corresponding to the same matched MAC address in the MAC table so as to identify the equipment. That is, the MAC address 1A1B1C1D of the address resolution protocol message matches the same MAC address in the MAC table, and since the MAC message has been received by the management module and stored in the MAC table, the current MAC table contains a row record of "1 A1B1C1D, PORT 1", and then the MAC address 1A1B1C1D of the addressable resolution protocol message matches the row record of "1 A1B1C1D, PORT 1" corresponding to the same MAC address in the MAC table, and then the row record of "1 A1B1C1D, PORT 1" is matched, and the PORT access PORT1 in the row record of "1 A1B1C1D, 1A1B1C1d, 192.168.1.1 and PORT1 is taken out, and the row record 1 of the device list is taken as the device identification information according to 1A1B1C1d, 192.168.1.1.3656 and PORT 1. After the management module receives the MAC message, the configuration protocol message and the address resolution protocol message when the three-address router accesses the main gateway:
the MAC table contains row records "1A 1B1C1D, PORT 1";
the network address table contains row records "1A 1B1C1D, 1A1B1C1d, 192.168.1.1"; (ii) a
The bridge address table contains row records "1A 1B1C1D, PORT 1".
The device list contains the row record "1 A1B1C1D, 1A1B1C1d, 192.168.1.1, PORT 1", i.e., row record 1 of the device list.
(1-2) as shown in fig. 10, the mobile phone 1 is accessed to the three-address router:
when the lower-hanging device of the three-address router is accessed into the system, the driving module cannot generate the corresponding network bridge address table, namely when the mobile phone 1 is accessed into the three-address router, the corresponding network bridge address table cannot be generated.
The actual access point of the mobile phone 1 is a three-address router, but not a main gateway, so that the main gateway cannot receive the MAC message when the mobile phone 1 accesses the three-address router;
the management module acquires a configuration protocol message, wherein the configuration protocol message carries a MAC address a1b1c1d1 and an IP address 192.168.1.11, the configuration protocol message carries a MAC address as a physical address, and then matches the MAC address in the bridge address table according to the MAC address a1b1c1d1 in the configuration protocol message (i.e. whether a row record corresponding to the MAC address same as the MAC address in the configuration protocol message is contained in the bridge address table is judged), if the same MAC address is matched in the bridge address table according to the MAC address a1b1c1d1 of the configuration protocol message, (indicating that the configuration protocol message is sent by a four-address router or a lower-hanging device of the four-address router), if the same MAC address is not matched in the bridge address table according to the MAC address a1b1c1d1 of the configuration protocol message, the configuration protocol message indicates that the same row record cannot be matched in the bridge address table (indicating that the configuration protocol message is a row record of the three-address router or the three-address router at the same row record cannot be matched in the configuration protocol message according to the MAC address a1b1c1d1 of the configuration protocol message Sent by the drop device of the address router), since the embodiment assumes that the handset 1 accesses the three-address router (i.e. the handset 1 gets the drop device as the three-address router), the MAC address a1b1c1d1 according to the configuration protocol message cannot be matched with the same MAC address in the bridge address table. At this time, it is determined whether the current network address table contains the row record that is the same as the IP address 192.168.1.11 of the configuration protocol message according to the IP address 192.168.1.11 of the configuration protocol message, because the embodiment assumes that the management module receives the configuration protocol message first, and therefore the management module has not received the address resolution protocol message sent by the mobile phone 1, the same IP address cannot be found in the network address table according to the IP address 192.168.1.11 of the configuration protocol message, at this time, the MAC address a1b1c1d1 and the IP address 192.168.1.11 of the configuration protocol message are stored in the row record 2 of the current network address table, and it is waited for the address resolution protocol message to initiate matching and update the network address table.
The method comprises the steps that a management module obtains an address resolution protocol message, wherein the address resolution protocol message carries an MAC address 1A1B1C1D and an IP address 192.168.1.11, and whether a current network address table contains a row record which is the same as the IP address of the address resolution protocol message or not is judged according to the IP address in the address resolution protocol message; since the management module has received the configuration protocol message sent by the mobile phone 1 and has stored the MAC address A1B1C1d1 and the IP address 192.168.1.11 of the configuration protocol message in the row record 2 of the network address table, it can match the same IP address in the network address table according to the IP address 192.168.1.11 in the address resolution protocol message, at this time, it is determined whether the MAC address 1A1B1C1D of the address resolution protocol message is the same as the MAC address corresponding to the row record in the network address table which is the same as the IP address of the address resolution protocol message, since the row record matched to the same IP address in the network address table according to the IP address 192.168.1.11 in the address resolution protocol message is "A1B 1C1d1, 192.168.1.1.1", it is known that the MAC address matched to the row record is A1B1C1d1, which is different from the MAC address 1A1B1C 56 of the address resolution protocol message, and the MAC address record matched to the address of the address resolution protocol message is "591C 1a 591C 1B 1d 461B 1, 192.168.1.1 ″, that is, the MAC address is updated to the row record 2 of the network address table (if the row record of the same IP address is matched in the network address table according to the IP address 192.168.1.11 in the address resolution protocol message, and the MAC address of the address resolution protocol message is not the same as the MAC address corresponding to the row record of the same IP address in the network address table, it indicates that the address resolution protocol message is sent by the three-address router or the drop-off device of the three-address router, but not sent by the four-address router or the drop-off device of the four-address router, and the MAC address of the address resolution protocol message is the physical address corresponding to the row record of the same IP address in the network address table, that is, a1b1c1d1 is the physical address). After updating the MAC address 1A1B1C1D in the address resolution protocol message to the row records "A1B 1C1d1, 192.168.1.11" corresponding to the different MAC addresses matched in the network address table, the network address table contains 1A1B1C1D, A1B1C1d1 and 192.168.1.11.
And finally, matching the same MAC address in the MAC table by using the MAC address of the message of the address resolution protocol, and if the same MAC address is matched, acquiring an access port corresponding to the same matched MAC address in the MAC table so as to identify the equipment. That is, the MAC address 1A1B1C1D matches the same MAC address in the MAC table according to the address resolution protocol message, and the MAC table containing the row record "1 A1B1C1D, PORT 1" is generated when the three-address router accesses the master gateway, so that the row records "1 A1B1C1D, PORT 1" corresponding to the same MAC address are matched in the MAC table according to the MAC address 1A1B1C1D of the address resolution protocol message, and the row records "1 A1B1C1D, PORT 1" are matched, and then the row records "1 A1B1C1D, PORT 1" are taken out, and 1A1B1C1d 1, 192.168.1.11 and PORT1 are put into the row record 2 of the device list according to the access PORT1 in the row record of A1B1C1d1, 192.168.1.11 and PORT1 as the device identification information. After receiving the configuration protocol message and the address resolution protocol message when the mobile phone 1 accesses the three-address router, the management module:
the row record in the MAC message is unchanged, still containing the row record "1A 1B1C1D, PORT 1";
the network address table contains row records "1 A1B1C1D, 1A1B1C1d, 192.168.1.1" and "1 A1B1C1D, A1B1C1d1, 192.168.1.11", namely row record 1 and row record 2, respectively, of the network address table.
The device list contains row records "1 A1B1C1D, 1A1B1C1d, 192.168.1.1, PORT 1" and "1 A1B1C1D, A1B1C1d1, 192.168.1.11 and PORT 1", i.e., row record 1 and row record 2, respectively, of the device list.
