Description

Management method, device and system of communication equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, and a system for managing a communication device.

Background

At present, each communication network comprises more communication devices, from a core layer to a convergence layer and then to an access layer, each network layer is composed of a large number of communication devices, particularly at the access layer, the communication devices access various service types and relate to communication devices of a plurality of different access manufacturers; therefore, in order to configure an Internet Protocol (IP) address for the existing communication device in the communication network and the management of the communication device that needs to be accessed, so as to implement centralized management, and to enable the requirements of universality, stability and high adaptability to be satisfied during centralized management, a zero-configuration centralized management scheme is provided, that is, the management of the communication device can be implemented by a network manager without manual configuration.

Currently, the centralized management of zero configuration for existing communication devices in a communication network can be divided into two categories: the first type is that a network manager actively allocates an IP address to a communication device after sensing that the communication device is online, and the IP address is allocated to each communication device mainly by using a Dynamic Host Configuration Protocol (DHCP) Protocol, but this management method is easily limited by an address pool range and a local area network.

The second type is that the communication device generates an IP address by default and sends a notification message to the network manager to enable the network manager to determine the IP address of the communication device, although the management method can avoid the problems in the First type of management method, because the method automatically generates the IP address by using an Open Shortest Path First (OSPF) protocol, the method is limited by the OSPF protocol and needs to ensure that all communication devices are in the same area; in addition, the OSPF Protocol is relatively complex to expand IPv6, which is a sixth version of the internet Protocol, and needs to use OSPFv3 Protocol to assist implementation, and at the same time, IP-MAC binding obtained by using Address Resolution Protocol (ARP) does not support IPv6, so that there are many limitations when using the OSPF Protocol to generate IP addresses to implement centralized management.

Detailed Description

The following describes a method, an apparatus, and a system for managing a communication device according to an embodiment of the present invention with reference to the accompanying drawings. The detailed description of the embodiments is given. It should be noted that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

An embodiment of the present invention provides a management method for a communication device, which is applied to a receiving device, and as shown in fig. 1, the management method may include:

s101, receiving a hello message (namely a hello message) which is sent by sending equipment after the first IP address is determined and carries a level area of the sending equipment in a network;

wherein, the first IP address can be an IPv4 address or an IPv6 address;

s102, establishing a neighbor relation with a sending device according to a level area of the sending device carried in the received hello message in a network and a preset establishment rule of the neighbor relation between devices in different level areas;

when sending a hello message, the sending equipment sends the hello message according to a preset sending period, and if the sending period is 10s, the sending equipment sends a hello message to the receiving equipment every 10 s; for the receiving device, after receiving the hello message, establishing a neighbor relation with the sending device according to information carried in the hello message and a preset establishment rule of the neighbor relation between devices in different hierarchical regions; certainly, after the neighbor relation is established, the receiving device will continue to receive the hello message sent by the sending device, and at this time, the neighbor relation is maintained; if the receiving device does not receive the hello message within a set time length (for example, three consecutive sending periods) due to some reasons after the neighbor relation is established, the receiving device will release the neighbor relation with the sending device until the relation is re-established after the hello message is received again.

S103, sending a feedback message carrying the established neighbor relation to sending equipment;

s104, receiving an LSP message which is sent by a sending device and carries link state information of the sending device and a first IP address;

in this step, the received LSP packet may be directly sent by the sending device, or may be forwarded or triggered to be sent by other nodes, for example, when the IS-IS routing protocol IS used, it may be sent by a pre-elected dummy node.

S105, according to the link state information and the first IP address of the sending device carried in the LSP message, determining a routing table containing the routing information and the first IP address of the sending device, so that the network manager at least manages the sending device according to the determined routing table.

In the management method for the communication device provided by the embodiment of the present invention, a DCN network management manner is adopted, according to a preset establishment rule of a neighbor relationship between devices in different hierarchical regions, and the neighbor relationship established between the sending device and the receiving device, a relationship can be established between two devices in different hierarchical regions, so that management of the communication device in a cross-hierarchical region is facilitated; moreover, the technical problem that the communication equipment in the core network sends Link State Advertisement (LSA) to all other communication equipment to cause the overload of the communication equipment can be solved when the existing OSPF protocol is based. In addition, the first IP address determined in the embodiment of the present invention may be not only an IPv4 address, but also an IPv6 address, that is, the management method for a communication device provided in the embodiment of the present invention is not limited to the encoding method of the network layer address, and has wide applicability.

In specific implementation, the established neighbor relationship with the sending device may be a neighbor relationship established by using an Intermediate System-to-Intermediate System (IS-IS) routing protocol, and the level area may be a level area; in order to enable the sending device and the receiving device to establish the IS-IS neighbor relationship, in the management method provided in the embodiment of the present invention, the rule for establishing the neighbor relationship between the devices in different hierarchical regions preset in step S102 may be: a neighbor relationship is allowed to be established between two communication devices in the same single rank region, and a neighbor relationship is allowed to be established between communication devices in compatible regions.

In a more specific embodiment, an IS-IS routing protocol may be used between two communication devices, and IS-IS employs a two-level hierarchy within a routing domain, where a large routing domain IS divided into multiple hierarchical domains: level-1, level-2 and level-1-2, the equipment in the level-1 area can establish IS-IS neighbor relation with the equipment in the level-1-2 area and the level-1 area, the equipment in the level-2 area can establish IS-IS neighbor relation with the equipment in the level-1-2 area and the level-2 area, but the device in level-1 area may not establish IS-IS neighbor relation directly with the device in level-2 area, at this time, in fact, level-1 area and level-1-2 area are compatible level areas, level-2 area and level-1-2 area are compatible level areas, but level-1 and level-2 regions belong to different and incompatible level regions.

Specifically, fig. 2 shows a schematic structural diagram of a DCN management network, where the entire network may be divided into 5 areas, where the area includes four edge networks, namely an edge network 1, an edge network 2, an edge network 3, and an edge network 4, and also includes a core network 5, and both the edge network and the core network include a plurality of routers (i.e., communication devices). When the DCN adopts the IS-IS routing protocol, the core network 5 IS a network that carries a large number of routes, so the area where the router located in the core network 5 IS generally set to be a level-2 area, for example, the router R3 IS located in the level-2 area; for the edge network 1, the route in the DCN data network can reach the network management without knowing the routes of other edge networks, so the area where the router located in the edge network 1 is arranged is set as a level-1 area, for example, the router R1 is located in the level-1 area, and the router R6 is also located in the level-1 area; for the router R2, since it is used for connecting with the core network 5, the area where the router R2 is located is set to be a level-1-2 area, and similarly, the router R7 is also located in the level-1-2 area, where the level-1-2 area indicates that the router R2 belongs to both the level-1 area and the level-2 area. Of course, the structure of the DCN management network is not limited to that shown in fig. 2, and here, only the level area where each router is located is illustrated by way of example, and the specific structure of the DCN management network is not limited herein.

Therefore, in the embodiment of the invention, the management of the communication equipment in a level region can be favorably realized by the IS-IS neighbor relation established between the two communication equipment based on the network management mode of the DCN of the IS-IS routing protocol; for example, since the router R1 and the router R2 both belong to a level-1 area, an IS-IS neighbor relationship may be established between the router R1 and the router R2; of course, both the router R2 and the router R3 are in a level-2 area, and although the router R2 and the router R3 belong to different networks, an IS-IS neighbor relationship may be established between the router R2 and the router R3; thus, the management of the router R1 can be realized through the router R2 and the router R3, and the centralized management of communication equipment crossing level areas is realized. Of course, this IS only an example, and in the actual management process, the management method based on the IS-IS routing protocol in the above example IS not limited, and IS not limited herein. Therefore, the following describes the management method provided by the embodiment of the present invention based on the IS-IS routing protocol.

It should be noted that, in the embodiment of the present invention, for a receiving device, in order to create an IS-IS process and establish an IS-IS neighbor relationship with a sending device, it IS not only necessary to perform initialization setting on the sending device, but also to perform initialization setting on the receiving device; therefore, in order to implement initialization setting on the receiving device, in the embodiment of the present invention, the method may further include:

determining a second IP address corresponding to the second MAC address according to a pre-configured local second MAC address; in the step, a second IP address is generated according to a preset rule according to a second MAC address, and the process can be realized by any mode in the prior art without special limitation; when the IP address type of the second IP address is known, the second IP address of the type corresponding to the second MAC address is directly determined according to the second MAC address; or when the type of the second IP address is unknown, respectively generating two types of IP addresses according to the second MAC address, and when receiving a message which is sent by sending equipment and carries the first IP address, selecting the IP address with the same type as the first IP address from the generated two types of IP addresses as the second IP address according to the type of the carried first IP address.

Specifically, when it is known that the type of the second IP address needs to be determined, the first IP address can be directly determined according to the second MAC address, and the type of the second IP address is made to be the required type; if the type of the second IP address needs to be determined, if the second IP address is unknown, in order to make the determined type of the second IP address conform to the current use environment and ensure normal management of the communication device, two types of second IP addresses can be respectively generated according to the second MAC address, that is, an IPv4 address and an IPv6 address can be respectively generated; and then determining the type of the second IP address according to the type of the first IP address carried in the received message sent by the sending equipment. The received packet carrying the first IP address may be an LSP packet, or may be another packet, which is not limited herein.

For example, when the type of the second IP address needs to be an IPv4 address, directly generating the second IP address satisfying the IPv4 address format according to the second MAC address; when the type of the second IP address is not determined, respectively generating an IPv4 address and an IPv6 address, and then selecting the second IP address meeting the IPv6 address format when the first IP address carried in the received LSP message is the IPv6 address.

Specifically, in the embodiment of the present invention, since the second MAC address of the receiving device is the unique identifier assigned to the receiving device by the manufacturer, and has the characteristic of uniqueness, the second IP address determined according to the second MAC address also has uniqueness, which can effectively reduce the operation and maintenance cost of the operator; the determined second IP address may be an IPv4 address, or an IPv6 address, and may be specifically determined according to the type of the first IP determined by the sending device.

In addition, based on the DCN management network shown in fig. 2, when determining the level area and the type of the second IP address where the receiving device is located in the network, the following may be implemented:

and determining the type of the second IP address and the grade area in the network in which the second IP address is positioned according to an externally input preset signal, the corresponding relation between the preset signal and the IP address type and the corresponding relation between the preset signal and the grade area in the network in which the second IP address is positioned.

Specifically, the determination process of the type of the second IP address and the rank region in the network where the second IP address is located can be implemented by triggering the corresponding setting function of software in the device through the input preset signal. The correspondence between the preset signal and the IP address type means: each input signal corresponds to an IP address type, and whether the IP address is IPv4 or IPv6 or further an uncertain type can be determined according to different input signals; the corresponding relation between the preset signal and the level area in the network where the preset signal is located refers to: each input signal corresponds to a grade area indicating the equipment; the preset signal input from outside can be input from outside of the device, and can be input through command line or other user interface, but preferably can be input by a preset network management dialer, which is used as a hardware input device, and can be selected intuitively and conveniently and directly according to the selected item to select the corresponding input signal.

Therefore, in the embodiment of the present invention, determining the type of the second IP address and the rank region in the network where the second IP address is located according to the externally input preset signal, the corresponding relationship between the preset signal and the IP address type, and the corresponding relationship between the preset signal and the rank region in the network where the second IP address is located may specifically include:

when determining the use environment of the second IP address, generating a first preset signal matched with the use environment of the second IP address by using a preset selection input of a network management decoder, and adjusting the type of the second IP address to be the same as the use environment of the second IP address (IPv4 or IPv 6); or, when the using environment of the second IP address is uncertain, the selection input of the network management decoder is utilized to generate a second preset signal matched with the compatible type, and the type of the second IP address is adjusted to be the compatible type suitable for IPv4 and IPv 6;

and generating a third preset signal matched with the level area in the network where the third preset signal is positioned by utilizing the selection input of the network management transcoder, and adjusting the level area where the third preset signal is positioned.

The process of selecting the type of the second IP address and the rank region in the network where the network management transcoder is located may be determined before networking, and of course, may also be determined after networking; therefore, in the embodiment of the present invention, the type of the second IP address of the receiving device and the time for selecting the rank region in the network are not limited, and may be set accordingly according to specific needs.

In the embodiment of the present invention, a schematic structural diagram of a network management transcoder is shown in fig. 3, where the network management transcoder is divided into an upper layer and a lower layer, and a black dot filling position indicates a current state; when the communication device IS placed in the 0/D file, it indicates that the current communication device uses the zero Configuration in the Operation Maintenance management (OAM) and Dynamic Host Configuration Protocol (DHCP) modes, and when the communication device IS placed in the OSPF file, it indicates that the current communication device uses the zero Configuration in the OSPF mode, and when the communication device IS placed in the level-1, level-2, and level-1-2 files, it indicates that the current communication device uses the zero Configuration in the IS-IS mode, and when the communication device IS placed in the level-1, level-2, and level-1-2 files, the upper IPv4 and IPv6 can be enabled.

For example, after the communication device is powered on, if the lower layer is placed in a level-1 level and the upper layer is placed in an IPv4only level, the type of the determined IP address is an IPv4 address; if the lower layer is placed in a level-1 grade and the upper layer is placed in IPv4 and IPv6 grades, determining that the type of the IP address can be compatible with an IPv4 address and an IPv6 address; if the lower layer IS placed in the non-IS gear, the upper layer does not take effect; therefore, the network management dialer can be used as an external input signal, which is beneficial to realizing the switching of the types of the IP addresses so as to meet the use environment of the current communication equipment, and can also be beneficial to quickly realizing the switching of different management modes so as to adapt to different management requirements, and meanwhile, the selection of the management modes is enriched. Of course, the network management dialer may be configured in other forms as long as it can perform corresponding function selection and generate corresponding input signals.

Of course, in order to realize centralized management of communication devices, generally, the type of the second IP address determined by the receiving device side is the same as the type of the first IP address determined by the transmitting device side, and therefore, after the first IP address is determined by the transmitting device side, the type of the second IP address can be adjusted for the receiving device side according to the type of the first IP address; of course, when the type of the first IP address is determined, that is, when the usage environment of the second IP address is determined, the selection input of the network management transcoder is utilized to generate a first preset signal matched with the usage environment of the second IP address, and the type of the second IP address is adjusted to be the same as the usage environment of the second IP address; if the type of the first IP address is not determined, namely the using environment of the second IP address is not determined, a second preset signal matched with the compatible type is generated by utilizing the selection input of the network management decoder, and the type of the second IP address is adjusted to the compatible type suitable for IPv4 and IPv 6.

For example, if it is determined that the type of the first IP is IPv4, the network management decoder in fig. 3 is placed in the "IPv 4 only" position, that is, a signal for adjusting the type of the second IP address to IPv4 is input by using the selection of the network management decoder, and then the type of the second IP address is adjusted to IPv4 through subsequent operations and processing; if the type of the first IP is not determined, the network management dialer can be placed in an 'IPv 4& IPv 6' position, namely a signal for adjusting the type of the second IP address to be a compatible type is input by utilizing the selection of the network management dialer, then the type of the second IP address is adjusted to be the compatible type suitable for IPv4 and IPv6 through subsequent operation and processing, and at the moment, the type of the local second IP address can be determined according to the received information of the sending equipment.

Similarly, the manner of determining the rank region in the network where the network management transcoder in fig. 3 (i.e., the receiving device) is located is similar to that described above, and reference may be specifically made to the above embodiment, and repeated details are not repeated.

In specific implementation, in the embodiment of the present invention, the received LSP packet sent by the sending device may also carry a Network Entity identifier (NET), so that the NET may be obtained by the following method:

creating a subinterface for each three-layer interface of the receiving equipment, and borrowing the determined second IP address from the created subinterface;

and determining NET corresponding to the second IP address according to the determined second IP address.

In order to ensure that the DCN in-band management of the communication device can be implemented through any one interface, after the second IP address is determined, a sub-interface needs to be created for each three-layer interface, and the sub-interfaces need to be encapsulated by using a uniform virtual local area network VLAN (e.g., 4093), and then all the created sub-interfaces borrow the determined second IP address in an address borrowing manner, thereby implementing the DCN in-band management of the communication device. It should be noted that, after the receiving device IS started, the receiving device defaults to creating an IS-IS process, and after the second IP address IS determined, a subinterface IS created by default; and after borrowing the second IP address in the created subinterface, the subinterface borrowed with the second IP address IS added into the IS-IS process, so that the management of the network manager on the sending equipment IS facilitated.

Moreover, based on the support of the IS-IS routing protocol to the IP protocol, NET corresponding to the second IP address needs to be determined, so that the process takes effect; the NET also needs to be carried in LSP messages. The NET is generally in the form of Area + System ID + SEL, wherein the SEL is generally used for representing the type of a network access point; since the System ID is generally determined based on the second IP address, the System ID also has uniqueness, and can represent a router as a unique identifier; the System ID may be obtained by adding 0 to each decimal digit of the second IP address to three digits and dividing the resulting product into three segments, for example, when the second IP address is 132.0.34.34, 132.000.034.034 is obtained after the addition, and 1320.0003.4034 is obtained after the division into three segments, so the System ID in NET is 1320.0003.4034.

For the Area in NET, the Area value generally used to indicate the set Area level value may be determined according to the gear position where the network management dialer is placed, for example, when the lower layer of the network management dialer is placed at level-1, the Area value may be 01; if the lower layer is arranged at level-2, the Area value can be 02; if the lower layer is placed at level-1-2, the Area value can be 01 and 02; of course, this is only an example, and the value of Area is not limited to 01 and 02, and is not limited thereto.

In summary, if the receiving device is in the level-2 area and the generated IPv4 address is 132.0.0.1/32, NET may be determined to be 02.1320.0000.0001.00; if the receiving device is in a level-1-2 area and the generated IPv4 address is 132.0.0.2/32, NET may be determined to be 01.1320.0000.0002.00 and 02.1320.0000.0002.00, respectively.

In specific implementation, in order to determine a routing table so that a network manager can manage a sending device at least according to the routing table, step S105 in the management method provided in the embodiment of the present invention determines, according to link state information and a first IP address of the sending device carried in an LSP packet, a routing table including routing information and the first IP address of the sending device, which may specifically include:

calculating the routing information of the sending equipment according to the link state information of the sending equipment carried in the LSP message;

and determining a routing table containing the routing information of the sending equipment and the first IP address according to the calculated routing information and the first IP address carried in the LSP message.

Specifically, the embodiment adopted when determining the routing table according to the routing information and the first IP address may be an embodiment known by those skilled in the art, as long as the routing table can be determined so as to facilitate the network manager to manage the sending device, and is not limited herein.

In specific implementation, in the embodiment of the present invention, in addition to the network management mode of the DCN using the IS-IS routing protocol, the LLDP protocol IS also used to maintain the first MAC address of the neighbor device (i.e., the sending device) on the communication device running the IS-IS routing protocol, and the LLDP protocol has good extensibility to the IPv6 address, so that the extension of the IPv6 network IS simpler and easier.

Specifically, in the management method provided in the embodiment of the present invention, as shown in fig. 4, the method may further include:

s401, receiving a Link Layer Discovery Protocol (LLDP) message which is sent by a sending device after the first IP address is determined and carries the first IP address and a first MAC address of the sending device;

s402, establishing an LLDP neighbor relation with a sending device according to a first IP address and a first MAC address carried by a received LLDP message;

In the management method for the communication device provided by the embodiment of the present invention, a DCN network management manner is adopted, according to a preset establishment rule of a neighbor relationship between devices in different hierarchical regions, and the neighbor relationship established between the sending device and the receiving device, a relationship can be established between two devices in different hierarchical regions, so that management of the communication device in a cross-hierarchical region is facilitated; and the technical problem that communication equipment in a core network sends LSA to all other communication equipment when the communication equipment is based on the existing OSPF protocol, so that the load of the communication equipment is overlarge can be solved. In addition, the first IP address determined in the embodiment of the present invention may be not only an IPv4 address, but also an IPv6 address, that is, the management method for a communication device provided in the embodiment of the present invention is not limited to the encoding method of the network layer address, and has wide applicability.

In a specific implementation, in order to send an LSP packet to a receiving device, in the management method provided in this embodiment of the present invention, sending a link state LSP packet carrying link state information of the sending device and a first IP address to the receiving device may specifically include:

when the sending equipment is determined to belong to a point-to-point network, sending an LSP message carrying link state information and a first IP address of the sending equipment to the receiving equipment;

and when the sending equipment is determined to belong to the broadcast network, sending the LSP message carrying the link state information and the first IP address of the sending equipment to the receiving equipment through a pre-elected pseudo node.

Specifically, it is necessary to first determine whether the transmitting device and the receiving device belong to the same network type before performing the above steps; when determining that the sending equipment and the receiving equipment belong to different network types, the network type of the sending equipment needs to be changed according to a preset network type changing mode, and then whether the sending equipment and the receiving equipment belong to the same network type is determined again; when the sending equipment and the receiving equipment are determined to belong to the same network type and are both point-to-point networks, sending an LSP message carrying link state information and a first IP address of the sending equipment to the receiving equipment; when the sending equipment and the receiving equipment are determined to belong to the same network type and are both broadcast networks, the LSP message carrying the link state information of the sending equipment and the first IP address is sent to the receiving equipment through a pre-elected pseudo node.

Specifically, as shown in fig. 8, a simple broadcast network may be configured such that routers R1 to R4 are connected to the same lan through lan switches, where when router R1 and R2 are in a level-1-2 area, router R3 IS in a level-1 area, and router R4 IS in a level-2 area, according to the IS-IS routing protocol, routers R1, R2, and R3 may form an IS-IS neighbor with each other, and routers R1, R2, and R4 may form an IS-IS neighbor with each other; for a simple point-to-point network diagram, as shown in fig. 9, there may be no local area network switch, but two routers are directly connected, when both router R1 and router R2 are in level-2 area, both router R3 and router R5 are in level-1 area, and router R4 IS in level-1-2 area, an IS-IS neighbor may be formed between router R1 and router R2, an IS-IS neighbor may be formed between router R3 and router R4, an IS-IS neighbor may be formed between router R4 and router R5, and an IS-IS neighbor may be formed between router R2 and router R4. Of course, the broadcast network and the peer-to-peer network are not limited to the structures shown in fig. 8 and 9, and are only illustrative and not limited herein.

Because the IS-IS routing protocol supports the DCN of the point-to-point network and the DCN of the broadcast network, different implementation modes can be adopted when the LSP message IS sent according to different network types; when the sending device and the receiving device are both point-to-point networks, the sending device can directly send the LSP message to the receiving device so that the receiving device can determine a routing table; when the sending device and the receiving device are both broadcast networks, the LSP packet needs to be sent to the receiving device through a pre-elected pseudo-node (Designated IS, DIS), so that waste of resources can be effectively avoided, and management efficiency of the communication device IS improved.

Of course, when it is determined that the sending device and the receiving device belong to different network types, the network type of the sending device needs to be changed according to a preset network type changing mode, so that the network types of the sending device and the receiving device are the same; if the sending equipment defaults to use the broadcast network to carry out management, the receiving equipment defaults to use the point-to-point network to carry out management, and when the current network type is the point-to-point network, the sending equipment can modify the network type into the point-to-point network through a command line after the sending equipment is online through the broadcast network; in addition, when the network types of the plurality of communication devices need to be changed, the network types of the communication devices can be sequentially changed from the device at the end of the network according to the command line, so that the management of the communication devices is realized.

In addition, in the embodiment of the present invention, the sending device determines whether the network types of the sending device and the receiving device are the same based on the receiving device, and of course, the receiving device may also determine whether the network types of the receiving device and the sending device are the same based on the sending device, and if not, the network type of the receiving device is changed to make the network types of the two devices the same.

It should be noted that the feedback message sent by the receiving device to the sending device may carry information of a network type default for the receiving device, so that the sending device may determine whether the sending device and the receiving device belong to the same network type according to the network type default for the receiving device carried in the feedback message and the network type default for the sending device (i.e., the sending device), thereby facilitating subsequent operation and processing of the sending device, and facilitating implementation of management of the communication device. Of course, the information of the network type set by the receiving device as a default may also be carried by another message sent by the receiving device to the sending device to inform the sending device, as long as the sending device can determine the network type set by the receiving device as a default, which is not limited herein.

In specific implementation, in order to determine the type of the first IP address, in this embodiment of the present invention, the method may specifically include:

generating a first preset signal matched with the use environment of a first IP address configured in advance by using the selection input of a preset network management decoder, and adjusting the type of the first IP address;

in addition, in order to determine the rank region in the network where the sending device (i.e., the sending device) is located, the method may specifically include:

and generating a second preset signal matched with the grade area in the network where the second preset signal is positioned by utilizing the selection input of the network management decoder, and adjusting the grade area where the second preset signal is positioned.

Specifically, for the sending device, the implementation that the type of the first IP address is adjusted by using the preset signal selectively input according to the network management transcoder, and the rank region in the network where the sending device (i.e., the sending device) is located is similar to that of the receiving device, which may specifically refer to the above contents, and repeated details are omitted. It should be noted that, since the type of the first IP address can be determined on the transmitting device side, the type of the first IP address can be determined directly by using the selection input of the network management transcoder.

In specific implementation, when the LSP packet sent to the receiving device also carries a network entity identifier NET, in the embodiment of the present invention, NET may be obtained by the following method:

creating a subinterface for each three-layer interface of the sending equipment, and borrowing the determined first IP address from the created subinterface;

and determining a network entity identifier NET corresponding to the first IP address according to the determined first IP address.

Specifically, for the transmitting device side, the process of determining NET is similar to the process of determining NET at the receiving device side, which may be referred to above specifically, and repeated details are not repeated.

It should be noted that, in the embodiment of the present invention, in addition to the network management manner of the DCN adopting the IS-IS routing protocol, on the communication device running the IS-IS routing protocol, the LLDP protocol IS also adopted to maintain the MAC addresses of the neighbor devices, and since the LLDP protocol has good extensibility to the IPv6 address, the extension of the IPv6 network IS simpler and easier.

Therefore, in the management method provided in the embodiment of the present invention, after determining the first IP address corresponding to the first MAC address according to the preconfigured first MAC address, as shown in fig. 10, the method may further include:

s1001, sending a Link Layer Discovery Protocol (LLDP) message carrying a first IP address and a first MAC address to a receiving device, so that the receiving device sends a feedback message carrying the LLDP neighbor relation after the LLDP neighbor relation between the receiving device and the sending device is established, an address table comprising the first IP address and the first MAC address is determined, and a network manager manages the sending device according to the determined address table and a routing table;

s1002, receiving a feedback message carrying the LLDP neighbor relation establishment sent by the receiving device.

Specifically, before step S1001 in the management method provided in the embodiment of the present invention sends a link layer discovery protocol LLDP packet carrying a first IP address and a first MAC address to a receiving device, the method may further include:

and setting the management address in the LLDP message as the determined first IP address.

Specifically, before sending an LLDP packet to a receiving device, the LLDP packet needs to be constructed, and the implementation manner is: and updating the Management address subtype and the value of the Management address field in the Management type length value Management TLV structure in the LLDP message into the determined first IP address so that the receiving device can determine an address table according to the first IP address and the first MAC address carried in the LLDP message after receiving the LLDP message, wherein the Management TLV structure in the LLDP message is shown in Table 1.

TABLE 1

The above management method provided by the embodiment of the present invention will be described in detail with reference to specific embodiments.

The first embodiment is as follows: taking the process of determining the routing table based on the IS-IS routing protocol as an example, and combining the flowchart of the method shown in fig. 11 and the interactive flowchart shown in fig. 12; the sending equipment is A, the receiving equipment is B, and the network types of the sending equipment and the receiving equipment are the same and are both point-to-point networks.

S1101, A sends a hello message carrying a level area of sending equipment in a network to B;

s1102 and B receive a hello message sent by A;

s1103 and B establish an IS-IS neighbor relation with A according to the grade area of A in the network carried in the received hello message;

s1104, B sends feedback information carrying the IS-IS neighbor relation to A;

s1105, A receives feedback information sent by B;

s1106, the A sends the LSP message carrying the link state information of the A and the first IP address to the B;

s1107 and B receive the LSP message sent by A;

s1108, B calculates the routing information of A according to the link state information of A carried in the LSP message;

s1109 and B, according to the calculated routing information and the first IP address carried in the LSP message, determining a routing table containing the routing information of A and the first IP address.

Through the routing table and the address table determined in the two embodiments, if the network manager needs to manage A, the network manager firstly sends a message carrying the first IP address of A to B; after receiving the message, B finds out corresponding routing information in the determined routing table according to the first IP address of A carried in the message, finds out a corresponding first MAC address in the determined address table, and then sends the first MAC address and the routing information to A as two-layer information, thereby realizing that the network manager manages A through B.

Therefore, in the IS-IS routing protocol and LLDP protocol adopted in the embodiment of the present invention, firstly, the IP address can be automatically announced to other communication devices through the IS-IS routing protocol, so as to implement the management feature of zero configuration, and thus, after a new communication device IS on line, the new communication device can be managed without any manual configuration by an operator maintenance staff; secondly, the IS-IS routing protocol IS a link state protocol, has the characteristic of automatically responding to the change of the link state, can transmit management channel information, can automatically converge to achieve the self-healing effect if the network topology changes or vibrates, and simultaneously ensures that the management channel address of the communication equipment can still be managed under the condition that the network vibrates or the link IS interrupted, thereby improving the management stability of the communication equipment; thirdly, the address table of the neighbor device is maintained by using the LLDP protocol, which has good expansibility to IPv6, so that the extension of the IPv6 network becomes simpler and easier.
