Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the 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.
Fig. 1 is a first flowchart of a method for determining a VLAN id according to an embodiment of the present invention, where the method for determining a VLAN id is applied to a routing module, and as shown in fig. 1, the method may include:
step 101: and receiving two VLAN identification numbers sent by the EOC module.
One VLAN identification number is the VLAN identification number of the routing module, and the other VLAN identification number is the VLAN identification number of the set-top box. After receiving the two VLAN identification numbers, the routing module cannot determine which VLAN identification number is its own and which VLAN identification number is for the set-top box.
Step 102: an initial IP request is determined.
The initial IP request is generated by the routing module or the set-top box.
After the convergence terminal is powered on, the set-top box and the routing module both need to generate an IP request for requesting an external network IP and send the IP request to the server, and the subsequent set-top box and the routing module can normally perform network work only after the server returns a corresponding IP address according to the IP request. The IP request needs to carry a VLAN identification number, the IP request without the VLAN identification number is an initial IP request, and the IP request written with the VLAN identification number is a complete IP request. The work of writing the VLAN identification number in the initial IP request is completed by the routing module. Since the routing module cannot determine which device the two VLAN identifiers correspond to, the routing module needs to first distinguish the device corresponding to the VLAN identifier by means of packet detection. For a specific packet detection process, see the following.
Step 103: and executing a data packet detection process until capturing a target network packet which is sent by the server and has the same network protocol type as the initial IP request.
The data packet detection process comprises the following steps: alternately performing for the two VLAN identification numbers: and writing a VLAN identification number into the initial IP request to generate a complete IP request, and sending the complete IP request to a server through an EOC module.
The packet detection process may specifically be: alternately performing at fixed time intervals for the two VLAN identification numbers: and writing a VLAN identification number into the initial IP request to generate a complete IP request, and sending the complete IP request to a server through an EOC module.
The network communication protocols of the set-top box and the routing module are different, the IP requests generated by the two devices are transmitted by using different network protocols, the IP request of the set-top box is transmitted by using a DHCP (Dynamic host configuration Protocol), which is a network Protocol of a local area network, and the IP request of the routing module is transmitted by using a PPPOE (Point to Point Protocol over Ethernet) Protocol.
Because different IP requests are transmitted by adopting different network protocols, the IP requests and the generating devices (set top boxes or routing modules) thereof have a first corresponding relation, and the VLAN identification codes and the devices (set top boxes or routing modules) have a second corresponding relation, the IP requests and the VLAN identification codes also have an indirect corresponding relation. In this embodiment, any one of the two VLAN identifiers is taken as the VLAN identifier corresponding to the initial IP request, and the corresponding VLAN identifier is written into the initial IP request, so as to generate a complete IP request. Then the complete IP request is sent to a server through an EOC module, and if the subsequent routing module receives a response packet of the server, the corresponding relation between the initial IP request and the VLAN identification code is determined to be correct; and if the response packet of the server is not received, writing another VLAN identification code into the initial IP request to generate a complete IP request, and sending the complete IP request to the server through the EOC module.
It should be noted that the server side is configured with the VLAN identifier of the set-top box and the VLAN identifier of the routing module. Only when the complete IP request is correct corresponding to the VLAN identification number carried by the complete IP request, the switch at the front side of the server end can send the complete IP request to the server according to the corresponding relation between the VLAN identification number and the communication protocol, and the server can respond to the corresponding response packet according to the complete IP request. Therefore, in this embodiment, the routing module writes any VLAN identification number into the initial IP request in a round-robin manner, generates a complete IP request, and sends the complete IP request to the server, and determines whether the VLAN identification number corresponds to the initial IP request according to a response condition of the server, thereby determining a correspondence between a device that generates the initial IP request and the VLAN identification number.
The target network packet also carries a VLAN identification number, and the VLAN identification number is the same as the VLAN identification number carried in the complete IP request received by the server. Because the VLAN tag occupies 4 bytes in the Ethernet frame, namely the data frame with the VLAN tag has 4 bytes more than the common Ethernet frame, the 4 bytes contain the tag protocol identification with 2 bytes and the tag control information with 2 bytes, and whether the network packet carries the VLAN identification number or not can be distinguished by distinguishing the length of the Ethernet frame.
After step 103, the process proceeds to step 104.
Step 104: and determining the VLAN identification number in the target network packet as the VLAN identification number of the device generating the IP request, and correspondingly determining the other VLAN identification number as the VLAN identification number of the other device.
After receiving a response packet returned by the server according to the complete IP request, the routing module may determine that the VLAN identifier in the complete IP request packet is the VLAN identifier of the device that generated the initial IP request, and that another VLAN identifier corresponds to the VLAN identifier of another device.
In this embodiment, the method for determining a VLAN identification number of a virtual local area network first receives two VLAN identification numbers sent by an EOC module, then determines an initial IP request, and performs a packet detection procedure with a carrier using the initial IP request as the VLAN identification number for the two VLAN identification numbers until a target network packet which is sent by a server and responds to the IP request and has the same network protocol type as the initial IP request is captured, and finally determines the VLAN identification number in the target network packet as a VLAN identification number of a device which generates the initial IP request, and correspondingly determines another VLAN identification number as a VLAN identification number of another device. The method realizes the distinguishing of the two VLAN identification numbers through the routing module without the need of conversion chip processing, reduces the volume of the fusion terminal and saves the production cost of the fusion terminal.
In a case that the initial IP request is a set-top box IP request, and the target network packet is a DHCP packet, referring to fig. 2, fig. 2 is a second flowchart of a method for determining a VLAN identifier in a virtual local area network disclosed in the embodiment of the present invention, where the method for determining a VLAN identifier may include:
step 201: and receiving two VLAN identification numbers sent by the EOC module.
One VLAN identification number is the VLAN identification number of the routing module, and the other VLAN identification number is the VLAN identification number of the set-top box
Step 202: an initial IP request for the set-top box is determined.
The set-top box initial IP request is generated by the set-top box and then sent to the routing module. All data interaction between the set-top box and the server needs to be relayed through the routing module.
Step 203: and executing the data packet detection process until the DHCP packet sent by the server is grabbed.
The data packet detection process comprises the following steps: alternately performing for the two VLAN identification numbers: and writing a VLAN identification number into the set-top box initial IP request to generate a set-top box complete IP request, and sending the set-top box complete IP request to a server through an EOC module.
Since the end numbers for DHCP network packets are UDP67 and UDP 68. It is possible to determine whether it is a DHCP packet by determining the port number in the network packet header.
Step 204: and determining the VLAN identification number in the DHCP packet as the VLAN identification number of the set top box, and determining the other VLAN identification number as the VLAN identification number of the routing module.
Of course, the initial IP request may also be a routing module IP request, and at this time, the target network packet is a PPPOE packet. The specific processing procedure is similar to that shown in fig. 2, and will not be described in detail here.
Since the response speed of the DHCP packet is usually faster than that of the PPPOE packet, the embodiment shown in fig. 2 may be adopted to determine the VLAN id of the VLAN in the case that there is no specific limitation in practical applications.
In other embodiments, after determining the VLAN identification number in the DHCP packet as the VLAN identification number of the set top box and determining another VLAN identification number as the VLAN identification number of the routing module, the method may further include: and generating a routing module complete IP request based on the determined VLAN identification number of the routing module, and sending the routing module complete IP request to a server through the EOC module.
The set top box and the routing module generate complete IP requests to be sent to the server, and when response packets returned by the server are received, the set top box and the routing module successfully apply for external network IP, and then the routing module and the set top box can perform normal data interaction with the server.
On the basis of the above embodiment disclosed by the present invention, fig. 3 discloses a third flowchart of a method for determining a VLAN id, where the method is applied to a routing module, and as shown in fig. 3, the method may include:
step 301: and receiving two VLAN identification numbers sent by the EOC module.
One VLAN identification number is the VLAN identification number of the routing module, and the other VLAN identification number is the VLAN identification number of the set-top box
Step 302: an initial IP request for a set-top box is determined.
The initial IP request is generated by the routing module or the set-top box.
Step 303: and executing the data packet detection process until the DHCP packet sent by the server is grabbed.
The data packet detection process comprises the following steps: alternately performing for the two VLAN identification numbers: and writing a VLAN identification number into the set-top box initial IP request to generate a set-top box complete IP request, and sending the set-top box complete IP request to a server through an EOC module.
Step 304: and determining the VLAN identification number in the target network packet as the VLAN identification number of the set top box, and correspondingly determining the other VLAN identification number as the VLAN identification number of the routing module.
Step 305: and setting network data parameters according to the determined VLAN identification number of the routing module and the VLAN identification number of the set-top box.
Setting network data parameters, subsequently adding the VLAN identification number of the determined set top box to the data sent by the set top box, adding the VLAN identification number of the determined routing module to the data generated by the routing module, and then sending the data to a server, so that the server can accurately receive the data sent by the set top box and the routing module. After receiving the data sent by the server, the routing module may also determine whether the data is sent to the routing module itself or the set-top box according to the VLAN identifier in the data, and if the data is sent to the set-top box, the routing module sends the data to the set-top box.
In this embodiment, after the VLAN identification numbers corresponding to the set-top box and the routing module are determined, network data parameters are set according to the determined VLAN identification number of the routing module and the determined VLAN identification number of the set-top box, so that it is ensured that subsequent data interaction between the routing module and the server, and between the set-top box and the server, can be performed normally and accurately.
While, for purposes of simplicity of explanation, the foregoing method embodiments have been described as a series of acts or combination of acts, it will be appreciated by those skilled in the art that the present invention is not limited by the illustrated ordering of acts, as some steps may occur in other orders or concurrently with other steps in accordance with the invention. Further, those skilled in the art should also appreciate that the embodiments described in the specification are preferred embodiments and that the acts and modules referred to are not necessarily required by the invention.
The method is described in detail in the embodiments disclosed above, and the method of the present invention can be implemented by various types of apparatuses, so that the present invention also discloses an apparatus, and the following detailed description will be given of specific embodiments.
Fig. 4 is a schematic view of a first structure of the apparatus for determining a VLAN id according to the present disclosure, where the apparatus for determining a VLAN id is applied to a routing module, and as shown in fig. 4, the apparatus 40 for determining a VLAN id may include:
a receiving module 401, configured to receive the two VLAN identifier sent by the EOC module.
One VLAN identification number is the VLAN identification number of the routing module, and the other VLAN identification number is the VLAN identification number of the set-top box. After receiving the two VLAN identification numbers, the routing module cannot determine which VLAN identification number is its own and which VLAN identification number is for the set-top box.
A request determining module 402 for determining an initial IP request.
The initial IP request is generated by the routing module or the set-top box.
After the convergence terminal is powered on, the set-top box and the routing module both need to generate an IP request for requesting an external network IP and send the IP request to the server, and the subsequent set-top box and the routing module can normally perform network work only after the server returns a corresponding IP address according to the IP request. The IP request needs to carry a VLAN identification number, the IP request without the VLAN identification number is an initial IP request, and the IP request written with the VLAN identification number is a complete IP request. The work of writing the VLAN identification number in the initial IP request is completed by the routing module. Since the routing module cannot determine which device the two VLAN identifiers correspond to, the routing module needs to first distinguish the device corresponding to the VLAN identifier by means of packet detection. For a specific packet detection process, see the following.
And a probe capture module 403, configured to perform a packet probe process until capturing a target network packet that is sent by the server and has the same network protocol type as the initial IP request.
The data packet detection process comprises the following steps: alternately performing for the two VLAN identification numbers: and writing a VLAN identification number into the initial IP request to generate a complete IP request, and sending the complete IP request to a server through an EOC module.
The probe capture module may be specifically configured to: alternately performing at fixed time intervals for the two VLAN identification numbers: and writing a VLAN identification number into the initial IP request to generate a complete IP request, and sending the complete IP request to a server through an EOC module. And capturing a target network packet which is sent by the server and has the same network protocol type as the initial IP request.
The network communication protocols of the set-top box and the routing module are different, the IP requests generated by the two devices are transmitted by adopting different network protocols, the IP request of the set-top box is transmitted by adopting a DHCP protocol, and the IP request of the routing module is transmitted by adopting a PPPOE protocol.
Because different IP requests are transmitted by adopting different network protocols, the IP requests and the generating devices (set top boxes or routing modules) thereof have a first corresponding relation, and the VLAN identification codes and the devices (set top boxes or routing modules) have a second corresponding relation, the IP requests and the VLAN identification codes also have an indirect corresponding relation. In this embodiment, any one of the two VLAN identifiers is taken as the VLAN identifier corresponding to the initial IP request, and the corresponding VLAN identifier is written into the initial IP request, so as to generate a complete IP request. Then the complete IP request is sent to a server through an EOC module, and if the subsequent routing module receives a response packet of the server, the corresponding relation between the initial IP request and the VLAN identification code is determined to be correct; and if the response packet of the server is not received, writing another VLAN identification code into the initial IP request to generate a complete IP request, and sending the complete IP request to the server through the EOC module.
It should be noted that the server side is configured with the VLAN identifier of the set-top box and the VLAN identifier of the routing module. Only when the complete IP request is correct corresponding to the VLAN identification number carried by the complete IP request, the switch at the front side of the server end can send the complete IP request to the server according to the corresponding relation between the VLAN identification number and the communication protocol, and the server can respond to the corresponding response packet according to the complete IP request. Therefore, in this embodiment, the routing module writes any VLAN identification number into the initial IP request in a round-robin manner, generates a complete IP request, and sends the complete IP request to the server, and determines whether the VLAN identification number corresponds to the initial IP request according to a response condition of the server, thereby determining a correspondence between a device that generates the initial IP request and the VLAN identification number.
The target network packet also carries a VLAN identification number, and the VLAN identification number is the same as the VLAN identification number carried in the complete IP request received by the server. Because the VLAN tag occupies 4 bytes in the Ethernet frame, namely the data frame with the VLAN tag has 4 bytes more than the common Ethernet frame, the 4 bytes contain the tag protocol identification with 2 bytes and the tag control information with 2 bytes, and whether the network packet carries the VLAN identification number or not can be distinguished by distinguishing the length of the Ethernet frame.
An identification number determining module 404, configured to determine the VLAN identification number in the target network packet as the VLAN identification number of the device that generated the initial IP request, and correspondingly determine another VLAN identification number as the VLAN identification number of another device.
After receiving a response packet returned by the server according to the complete IP request, the routing module may determine that the VLAN identifier in the complete IP request packet is the VLAN identifier of the device that generated the initial IP request, and that another VLAN identifier corresponds to the VLAN identifier of another device.
In this embodiment, the device for determining a VLAN identification number of a virtual local area network first receives two VLAN identification numbers sent by an EOC module, then determines an initial IP request, and performs a packet detection procedure with a carrier using the initial IP request as the VLAN identification number for the two VLAN identification numbers until a target network packet which is sent by a server and responds to the IP request and has the same network protocol type as the initial IP request is captured, and finally determines the VLAN identification number in the target network packet as a VLAN identification number of a device which generates the initial IP request, and correspondingly determines another VLAN identification number as a VLAN identification number of another device. The device realizes the distinguishing of two VLAN identification numbers, does not need to convert a chip for processing, reduces the volume of the fusion terminal and saves the production cost of the fusion terminal.
When the initial IP request is an initial IP request of a set top box and the target network packet is a DHCP packet, the probe capture module 403 may be configured to: and executing the data packet detection process until the DHCP packet sent by the server is grabbed. The identification number determination module 404 may be configured to: and determining the VLAN identification number in the DHCP packet as the VLAN identification number of the set top box, and determining the other VLAN identification number as the VLAN identification number of the routing module.
Of course, the initial IP request may also be a routing module IP request, and at this time, the target network packet is a PPPOE packet. The specific processing procedure is similar to that when the initial IP request is the set-top box initial IP request, and details are not repeated here.
