Quantification of the quality of spare links in a telecommunications network

Abstract

In a telecommunications network provisioned with a distributed restoration algorithm, the spare links via which disrupted traffic may be rerouted are categorized into different quality levels based upon their respective anticipated near term availability and reliability. There are a number of categories ranging from dedicated high quality spare links along fully functional spans to low quality spare links that act as replacements for multiple working links in the same span as the failed working link.
