METHOD AND NETWORK NODE FOR MANAGING RESOURCE ALLOCATION IN TRAFFIC RESTORATION

摘要

A method and a network node for managing allocation of network resources in restoration of traffic in a connection oriented network are disclosed. The method comprises restoring (104) a first traffic from a first path on an alternative path if the first path is affected by a first failure (102) and assigning (106) a reserved status to resources of the first path no longer used for carrying the first traffic. If a second path is affected by a second failure the method comprises restoring (114) a second traffic from the second path, wherein the restoration of the second traffic does not use the resources having the reserved status.
