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, which are used to solve the problems in the prior art that the protocol stack performs VLAN channel encapsulation of user data packets, excessive use of system resources and low encapsulation efficiency. A method for dividing multiple VLANs in an embodiment of the present invention includes: the egress module driver layer receives the user data packet from the protocol stack that has not been encapsulated by the VLAN channel; determines the corresponding VLAN protocol ID according to the user data packet; The data packet is encapsulated by the VLAN channel; the user data packet encapsulated by the VLAN channel is sent. Because the embodiment of the present invention realizes the VLAN channel encapsulation of user data packets at the driver layer, it is not necessary to construct a VLAN node every time a VLAN interface is established, nor does it need to carry out encapsulation of the VLAN layer protocol stack delivered between cross-device nodes, thereby reducing the need for Use of system resources and improve the efficiency of encapsulation.

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...
