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.
