Abstract
A facility is provided for enhancing the reliability of a communications network so that traffic whose flow is disrupted by, for example, a faulty link, may be quickly restored to service. In particular, such traffic is restored to service by establishing a number of orders of connectivity each formed from spare link capacity, in which each succeeding order of connectivity represents the shortest loop around a preceding order of connectivity.
