Abstract

The present invention provides a method and an apparatus for computing cross-layer separated service paths, and a communications system. The method includes: acquiring path information about two physical-layer separated paths from a service starting point to a service end point on a physical network; updating a link cost of each IP link segment on a router network according to the path information about the two physical-layer separated paths; and computing path information about two corresponding router-layer separated paths on the router network according to the updated link cost of each IP link segment. The technical solutions provided in embodiments of the present invention can ensure that an appropriate physical-layer pipe resource is allocated for each router-layer separated path and avoid service congestion due to an algorithm.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a method, device and communication system for calculating a service cross-layer separation path. Background technique [0002] In a traditional core bearer network, the underlying physical network usually provides traffic pipes, and the upper-layer router network completes service routing planning and management. The above-mentioned underlying physical network is mostly an Optical Transport Network (OTN) network. To ensure Transmission quality. The core network usually needs to provide the ability to resist a fiber cut for each service. For example, a layer-by-layer protection method can be adopted. First, 1+1 link protection is provided on the upper router network, that is, the IP layer, and then The OTN layer performs 1+1 protection for each IP layer path. In this application scenario, the OTN layer needs four bandwidth resources to prov...
