Embodiment 6

[0110] Such as figure 2 Shown, the embodiment of the present invention six divides the method for multi-VLAN comprising:

[0111] Step 200, the application layer obtains the first user group list and the second user group list according to the group division rule.

[0112] Step 201, the application layer sends the first user group list to the entry module driver layer.

[0113] Step 202, the application layer sends the second user group list to the egress module driver layer.

[0114] Step 203, the entry module driver layer obtains the user information in the passing user data packet.

[0115] Step 204, the entry module driver layer searches the first user group list for a user tag corresponding to the user information.

[0116] Step 205, the driver layer of the entry module adds the user mark to the relevant information of the user data packet.

[0117] Step 206, the entry module driver layer sends the user data packet through the protocol stack.

[0118] Step 207, the ...

Abstract

The invention provides a method and equipment for dividing multiple VLANs (Virtual Local Area Network), which are used for solving the problems of high use frequency and low packaging efficiency of system resources when VLAN channel packaging of a user data packet is performed in a protocol stack in the prior art. The method for dividing the multiple VLANs comprises the steps that the user data packet which is not subjected to the VLAN channel packaging and comes from the protocol stack is received by an exit module driving layer; a corresponding VLAN protocol ID is determined according to the user data packet; the VLAN channel packaging is performed on the user data packet according to the VLAN protocol ID; the user data packet subjected to the VLAN channel packaging is sent. According to the method disclosed by the embodiment of the invention, the VLAN channel packaging of the user data packet is realized on the driving layer, a VLAN node does not need to be constructed every time when a VLAN interface is established, and VLAN layer protocol stack packaging transferred across equipment nodes is not needed, therefore, the use frequency of the system resources can be reduced, and the packaging efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and equipment for dividing multiple VLANs. Background technique [0002] VLAN (Virtual Local Area Network, Virtual Local Area Network) is a new data exchange technology that divides devices in a local area network into network segments logically rather than physically, thereby realizing virtual workgroups. Because it is logically divided rather than physically divided, each workstation in the same VLAN is not limited to the same physical range, that is, these workstations can be in different physical LAN (Local Area Network, local area network) networks. part. The broadcast and unicast traffic within a VLAN will not be forwarded to other VLANs, which helps to control traffic, reduce equipment investment, simplify network management, and improve network security. [0003] At present, there are many standards for dividing VLANs, such as: dividing VLANs acc...
