Abstract

This talk is on a novel dynamic survivable routing scheme, namely DJH. The proposed scheme is featured by a joint design for the optical layer monitoring plane and survivable routing, where monitoring trails (m-trails) are launched and can possibly reuse the spare capacity reserved for protection lightpaths (P-LPs). We will demonstrate how the proposed scheme determines the working lightpath (W-LP) and the corresponding P-LP(s), along with the configuration of the alarm code table (ACT) at each node, for each newly arrived connection request, where the targeted all-optical restoration can be fully ensured. Extensive simulation is conducted to examine the proposed DJH scheme in terms of blocking probability and compare it with a couple of previously reported counterparts, namely a p-Cycle based dynamic routing scheme and a failure dependent protection (FDP) based survivable routing scheme without considering all-optical monitoring.
