Abstract

A service route determination method and a relevant apparatus. In some feasible implementation manners of the present invention, a network device obtains N IP layer route groups that satisfy a topology constraint of a network IP layer and a requirement constraint of a service group; and if M transport layer route groups are successfully obtained, wherein each transport layer route group in the M transport layer route groups satisfies a topology constraint of a network transport layer, the requirement constraint of the service group, and a constraint of an IP layer route group corresponding to each transport layer route group in M IP layer route groups, and has the lowest device cost, selects a pair of IP layer route group + transport layer route group with the lowest device cost for the service group. The innovation mechanism helps to effectively reduce the device cost of the service route.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a service route determination method and a related device. Background technique [0002] Currently, the core bearer network may include a two-layer architecture of an Internet Protocol (IP, Internet Protocol) layer plus a transport layer (such as an optical layer). The transport layer provides traffic pipelines, and the IP layer provides service routing capacity planning. [0003] Before establishing service IP layer routing and transport layer routing, it is usually necessary to plan service-feasible IP layer routing and transport layer routing. In the prior art, when planning service IP layer routing and transport layer routing, it is usually mainly based on the consideration of transmission performance, arbitrarily plans an IP layer routing group with high transmission performance for the service group, and then according to the IP layer The routing group const...
