Abstract

The present invention provides a method and device for sending a control message, wherein the method includes: a first network-side edge device PE receiving a first control message from a second PE, wherein the first control message is used to communicate with the first The state of the physical port of the first access circuit AC connected to the PE is set to a predetermined state; the first PE sends a second control message to the second PE according to the predetermined state and the actual state of the physical port of the first AC, wherein the first The second control message is used to control the state of the physical interface of the second AC connected to the second PE. The present invention solves the deadlock problem of end-to-end fault transmission existing in the related art, and further achieves the effect of avoiding the deadlock problem of end-to-end fault transmission.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for sending a control message. Background technique [0002] In order to meet the trend of MAN business transformation and triple play integration, network operators tend to use efficient and low-cost packet transport networks to realize multi-service bearer, provide flexible network services, improve network resource utilization, and reduce network deployment complexity. degree, enhance the flexibility of network services, and bring more economic benefits to it. [0003] Layer 2 Virtual Private Network (L2VPN for short) is a technology that relies on Internet service providers and network service providers to establish a private data communication network in a public network. It can be divided into two business models: Virtual Private Lan Service (VPLS for short) and Virtual Leased Line (VLL for short). The former is based on Ethernet service forwarding and...
