METHOD FOR PROCESSING MULTI-DOMAIN PATH CALCULATION FAILURE AND PCE

摘要

A method for processing a failure of a multi-domain path computation and a Path Computation Element (PCE) are provided. The method for the PCE of a head domain includes: a failed link leading to a failure to compute a path according to a first domain sequence is acquired; the failed link is deleted from a first topology to obtain a second topology; a second domain sequence is determined according to the second topology; and a path computation for the second domain sequence is initiated.

1. A method for processing a failure of a multi-domain path computation, which is applied to a Path Computation Element (PCE) of a head domain, comprising:
acquiring a failed link leading to a failure to compute, according to a first domain sequence, a path; deleting the failed link from a first topology to obtain a second topology; determining a second domain sequence according to the second topology; and computing a path according to the second domain sequence.
