METHOD AND APPARATUS FOR UPDATING LABEL-SWITCHED PATHS

摘要

A method of updating a label-switched path for forwarding data in a data communications network in response to a change in a network comprises the step, performed at an updating node of receiving notification of a network change, of constructing a post-change label-switched path in the changed network. The method further comprises, after termination of a first period, forwarding data using the post-change label-switched path.
