Abstract

The invention provides a pseudo-wire service forwarding method and device. The pseudo-wire service forwarding method is applied to a multiprotocol label switching communication network. The method comprises the following steps that: a first provider edge (PE) establishes a pseudo-wire load sharing group, wherein the pseudo-wire load sharing group comprises a plurality of pseudo-wires; and the first PE performs load sharing processing in a forwarding service through the pseudo-wire load sharing group. Through adoption of the pseudo-wire service forwarding method and device, the problem of overlong master-slave switching time under the situation of pseudo-wire service forwarding resource waste and / or link fault in the prior art is solved; pseudo-wire service forwarding resources are saved; and the convergence speed is increased.

Description

technical field [0001] The invention relates to the field of data network communication, in particular to a method and device for forwarding pseudowire services. Background technique [0002] In the multiprotocol label switching (Multiprotocol Label Switching, also known as MPLS) communication network, especially the two-layer virtual private network (also called L2VPN, two-layer VPN) provides the two-layer virtual private network (VPN) service based on the MPLS network, so that Operators can provide Layer 2 VPNs based on different data link layers on a unified MPLS network, including Asynchronous Transfer Mode (ATM), Frame Relay (FR), Virtual Local Area Network (VLAN), Ethernet (Ethernet), and Point-to-Point Protocol (PPP) etc. Simply put, MPLS L2VPN transparently transmits user Layer 2 data on the MPLS network. From the user's point of view, the MPLS network is a Layer 2 switching network, which can establish Layer 2 connections between different nodes. [0003] Pseudow...
