Title:
PATH COMPUTATION METHOD, TUNNEL ESTABLISHMENT METHOD, PCC, PCE, PATH COMPUTATION SYSTEM AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2016/058299
Kind Code:
A1
Abstract:
Disclosed is a path computation method, comprising: receiving, by a path computation element (PCE), a path computation request from a path computation client (PCC), wherein the path computation request carries path computation constraint information including a basic path computation constraint and a custom path computation constraint; computing, by the PCE, a path based on the basic path computation constraint and the custom path computation constraint to obtain a first path computation result; and sending, by the PCE, the first path computation result to the PCC. Also disclosed at the same time are a tunnel establishment method, a PCE, a PCC and a path computation system.
