Abstract

The invention provides a method and device for realizing automatic assignment of link weights, and relates to the field of big data. The method comprises the following steps: acquiring network topology information and flow planning forwarding path information; determining a corresponding link weight prediction model according to the network topology information; converting the flow planning forwarding path into a path forwarding matrix; and inputting the path forwarding matrix into a trained link weight prediction model to obtain a weight value of each link in the network topology. According to the method, the strong learning capability of the link weight prediction model is fully utilized, and heuristic search does not need to be carried out by utilizing a network simulation tool, and theweight of each link can be quickly assigned.

Description

technical field [0001] The present disclosure relates to the field of big data, and in particular to a method and device for realizing automatic assignment of link weights. Background technique [0002] Inside an IGP (Interior Gateway Protocol, interior gateway protocol), the path of a message from one router to another router is determined by a route, and usually the route corresponds to the shortest path. In the network planning stage, when the physical topology of the network is determined (that is, where to place routers and which routers are connected by links), it is necessary to assign link weights to determine the link between any two routers. The packet forwarding path, also known as the traffic path. [0003] In an actual network, when it is necessary to assign a link weight, it is often set by experience and a symmetrical topology. Or use network simulation to continuously try the weights until the ideal result is found. The main problem of this method is that ...
