Abstract

See full text

A method of providing at least one restoration path for a primary routing path in a network. The method includes receiving a customer connection request to route information. Costs are assigned for the primary routing path, and the primary routing path is computed based upon the primary routing path costs. A backtracking distance over the primary routing path is determined, and costs for at least one restoration path are assigned. The at least one restoration path may then be computed based upon the at least one restoration path costs.
