Abstract

A system and method for realizing dual-node interconnection pseudo-wires relate to the technical field of wireless backhaul network applications. The system includes two bridge nodes, at least one access side node and at least one core side node, the two bridge nodes are respectively connected to each An access-side node and each core-side node are connected, and the two bridge nodes are divided into an active node and a standby node. Both the active node and the standby node are provided with an access-side interface, a dual-node interconnection pseudo-wire-side interface and a core side interface, and any two interfaces on the same bridge node communicate with each other; a dual-node interconnection pseudo-wire side virtual circuit is set between the active node and the standby node, and the access-side node is connected to the active node and the standby node respectively. There is an access side virtual circuit, the virtual circuit on the side of the dual-node interconnection pseudo-wire and the virtual circuit on the access side are bound in a dual-node interconnection pseudo-wire group, and the virtual circuit on the side of the dual-node interconnection pseudo-wire and the virtual circuit on the access side are There are respectively superimposed automatic protection switching signaling channels.

Description

technical field

[0001] The invention relates to the technical field of wireless backhaul network applications, in particular to a system and method for realizing double-node interconnected pseudowires. Background technique

[0002] As LTE (3GPP Long Term Evolution, 3GPP technology long-term evolution technology) is gradually being widely used in China, higher requirements are put forward for the wireless backhaul requirements of base station data services. At present, for its application in the wireless backhaul network, the common business model is to deploy L2 network (Layer 2 network) at the access layer, deploy L3 network (Layer 3 network) at the core layer, and complete L2 network to L3 network through the bridge interface at the aggregation node. Network business transformation.

[0003] The L2 network is a switched network, which implements point-to-point communication channels for service forwarding through end-to-end pseudo-wire technology. , label switching path)...
