Embodiment Construction

[0023] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

[0024] The invention firstly evaluates the port load status, and selects the route according to the evaluation result. The evaluation result of the port load status evaluation is obtained through the method of weight analysis, that is, the port load status (including but not limited to port bandwidth status, port bandwidth occupancy rate status, port overload status and port activation status) is firstly calculated. Values ​​or value ranges are defined as weights of different sizes and positive or negative, and then weighted to obtain port load weights that reflect the evaluation results of port load conditions. Calculate the load weight value of each port. The higher the weight value, the better the load status of the port, which also means that the port can bear more load. The routing strategy can select the port with the best load status according to ...

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...
