Fault-localization comparative study of deploying monitoring trails to achieve survivability in all-optical networks

In this paper, desirable performance of fault localization process in all-optical networks, by employing the recently introduced Monitoring-Trail (m-trail), is explored and a focus is given to the analysis on using m-trails with established lightpaths. A novel technique based on Geographic Midpoint Technique, an adapted version of the Chinese Postman´s Problem (CPP) solution and an adapted version of the Traveling Salesman´s Problem (TSP) solution algorithms is introduced. Examples are given to illustrate these techniques with a brief description on its establishment algorithms. A problem definition and an analysis of m-trail deployment to perform fault localization survivability in all-optical networks are presented. An optimized solution of the m-trail deployment procedure in all-optical networks that already established lightpaths is carried out by using FICO Xpress Mosel optimizer version 3.2.3.
