US 2020/0092195 A1 · PATH SELECTION METHOD AND APPARATUS

Abstract

The present application describes a path selection method and apparatus. The method may include obtaining a required latency of a service. The method may further include determining a target path for the service from m strict explicit paths based on the required latency, where a latency of the target path is less than or equal to the required latency, all the m strict explicit paths are unallocated paths, any subpath of a first strict explicit path in the m strict explicit paths exists in only the first strict explicit path, the first strict explicit path is any path in the m strict explicit paths, and m is an integer greater than or equal to 1. The present invention is applicable to the field of communications technologies and resolves at least a problem where a path computation element (PCE) cannot ensure that a path allocated to a service can meet a latency requirement of the service.
