Problems solved by technology

That is to say, in the prior art, it is impossible to use the same tunnel MAC address to be compatible with the transparent transmission of multiple Layer 2 protocol tunnels
The transparent transmission of conflicting Layer 2 protocol packets requires different tunnel MACs, which limits the expansion of Layer 2 protocol tunnels, increases the implementation complexity of Layer 2 protocol tunnels, and has the defect of poor flexibility.

Abstract

The invention relates to the field of network communication. The invention provides a method for realizing tunnel-induced transmission of two-layer protocol message of different types by using the same tunnel MAC address. The method for tunnel-induced transmission of two-layer protocol messages comprises: a, terminal entrance end equipment acquires an original two-layer protocol message and the type of message; b, the tunnel entrance end equipment adds a virtual local area network tag VLAN TAG field to the original two-layer protocol message, sets a field value indicating the type of the message in a specific field of the original layer-two protocol message according to the type of the message and acquires the revised two-layer protocol message; c, the tunnel entrance end equipment carries out tunnel message encapsulation of the revised two-layer protocol message and transmits the tunnel message; d, tunnel exit end equipment converts the revised two-layer protocol message into the original two-layer protocol message and transmits the original two-layer protocol message to a target user. The method contributes to the expansion of two-layer protocol channel and has good flexibility.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method and system for layer-2 protocol control in a layer-2 switching network, and also relates to a method for identifying and restoring the layer-2 protocol for tunnel transparent transmission. technical background [0002] Layer 2 protocol tunneling technology allows the Layer 2 protocol of remote user networks to tunnel through the Layer 2 switching network of the network provider to realize protocol interaction between user networks in different regions and realize remote Layer 2 protocol functions. Layer 2 protocol packets are transparently transmitted in the tunnel. The format of the Layer 2 protocol packet is as follows: [0003] DMAC SMAC Length DSAP SSAP CNTL …… [0004] Among them, DMAC indicates the destination MAC address of the protocol message; SMAC indicates the source MAC address of the protocol message; Length in...
