Abstract

The present invention provides a method for service forwarding and link change notification, a convergence device and an access device, wherein the service forwarding method is applied to multi-protocol label switching MPLS, including: when the access device only supports the two-layer protocol, the convergence device Judging whether the received spanning tree STP protocol message is an STP link change message, wherein the STP link change message carries STP link change information; The link change information determines the service forwarding path; the aggregation device forwards the service according to the service forwarding path. The present invention solves the problem of interruption of the downstream user network caused by failure of the switch network when the access device only supports the L2 layer protocol in the related art, and reduces the occurrence probability of service flow interruption.

Description

technical field [0001] The invention relates to the field of data network communication, in particular to service forwarding, link change notification method, convergence equipment and access equipment. Background technique [0002] With the rapid development of network scale and continuous improvement of network quality requirements, network applications have higher and higher requirements for reliability, and various link protection mechanisms have emerged. Currently, the commonly used multi-protocol label switching (also known as MPLS) and Virtual Routing Redundancy Protocol (also known as VRRP), realizes the backup between network layer devices at the same level. The simple detection and election mechanism provided by the VRRP protocol at the network layer can quickly realize the backup switchover in case of equipment failure. For general configurations, it takes 3-5 seconds, which can basically meet the uninterrupted requirements of the business. The imported device mu...
