Link Aggregation Convergence Method and Device for Distributed Switching Equipment

Abstract

The invention discloses a link aggregation and convergence method and device of a distributed switching device. The method comprises that when it is detected that a link aggregation member port of a service card of the distributed switching device is faulty, the CPU of the service card sets a local switching chip, The service flow of the faulty member port is protected by the local switch chip; the service card switches the service flow to the non-faulty member port; the service card sends the fault information to the main control card, and the main control card notifies each service card to converge and update the link The aggregation aggregation table can avoid inter-card communication and main control processing, save service notification processing time, and ensure that the services that should be sent out from the faulty member port are quickly switched to other member ports, which greatly reduces the convergence time and the convergence time. It is relatively stable, and the service flow of the faulty member port will be transferred to other non-faulty member ports, which ensures the globality of service flow processing and improves the speed and efficiency of link aggregation convergence.

Description

technical field [0001] The present invention relates to the field of distributed switching and forwarding, in particular to a method and device for link aggregation and convergence of distributed switching equipment. Background technique [0002] Link aggregation is widely used in network equipment due to its expansion of line bandwidth and engineering redundancy. However, if a link aggregation member port fails, the service flow that needs to pass through the faulty member port cannot be switched to the path in time. Packet loss; the convergence of link aggregation is to switch the route selection of the service flow, but if the convergence time is too slow, the service will be interrupted for a long time, and this problem is especially obvious on distributed devices, and it is very important to reduce the convergence time. important. [0003] At present, most manufacturers use the more traditional link aggregation convergence method to solve distributed aggregation conver...
