Analysis and Algorithms for Partial Protection in Mesh Networks

Free registration required

Executive Summary

Mesh networks supporting data rates of multiple gigabytes per second are being deployed to meet the increasing demands of the telecom industry. As data rates continue to increase, the failure of a network line element or worse, a fiber cut, can result in severe service disruptions and large data loss, potentially causing millions of dollars in lost revenue. Currently, there exist few options for protection that offer less than complete restoration after a failure. Due to the cost of providing full protection, many service providers offer no protection whatsoever.
