Multiple port path selecting method for network equipment

Abstract

A network equipment multiple port channel selection method includes evaluating every output port load status of network equipment according to port band width and flow rate load status, to obtain every output port load status evaluating result, in service retransmission, querying every output port load status evaluating result, comparing evaluating result, preference selecting large load-carrying capacity port to make service retransmission. Making weight value analyzing to evaluating result, defining band width factor and flow rate capacity factor value taking or value taking interval to different size and positive-negative weight value, then to make weighing to obtain port load weight value reflecting port load status evaluating result. The present invention makes multiple path outlet channel selection according to port load status weight value, raising channel selection rationality.

Description

technical field [0001] The invention relates to the technical field of communication, and in particular to a method for network equipment to perform multi-port route selection. Background technique [0002] During the outbound port scheduling process of message forwarding on a router or multi-service switch, if there is a backup route or backup path, it often performs multi-way outbound route selection scheduling between different ports, and different scheduling strategies and algorithms emerge as the times require. . Routing load sharing is the most common and typical application, and there are also applications such as FE trunk (Fast Ethernet port aggregation) routing and QOS (Quality of Service) routing, because routing load sharing is the most common multi-exit routing The application environment of the policy, the following uses routing load sharing as an example to illustrate the application environment of the multi-outlet route selection policy. [0003] In the curr...

Problems solved by technology

[0010] The technical problem to be solved by the present invention is to overcome the disadvantages that the existing multi-port route selection method cannot be dynamically adjusted according to the actual load conditions of the ports, and the flow cannot be accurately distributed to ports with higher load capacity, and to provide a network The device multi-port route selection method comprehensively considers the impact of port bandwidth and port load on route selection to improve the rationality of route selection
