Abstract

The present application provides a method and an apparatus for load sharing of pseudowires, which are applied in a scenario where a first operator's edge PE device is respectively connected to at least one second PE device through at least two PWs. The method includes: the first PE device receives a data flow from a user edge CE device, and forwards the data flow to a PW trunk interface, and the PW trunk interface is associated with at least two active PWs. The first PE device performs load sharing processing on the data flow, and forwards the data flow through the at least two active PWs. It is helpful to use PW to transmit large data traffic.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a method and device for pseudowire load sharing. Background technique [0002] Pseudo-Wire Emulation Edge to Edge (PWE3) refers to imitating Asynchronous Transfer Mode (ATM), Frame Relay ( Frame Relay, FR), Ethernet, low-speed time division multiplexing (Time Division Multiplexing, TDM) circuit and asynchronous optical network (Synchronous Optical Network, SONET) / asynchronous digital heterogeneous (Synchronous Digital Hierarchy, SDH) and other basic behaviors and characteristics A Layer 2 service bearer technology. [0003] Multi-Protocol Label Switching (MPLS) PWE3 is an important technology in the metropolitan area network, through which the original access methods (such as ATM, FR, etc.) can be integrated with the existing IP backbone network The integration of the network together reduces the repeated construction of the network and saves operating...
