Performance comparison of agile optical network architectures with static vs. dynamic regenerator assignment

Abstract— Agile all optical cross-connect (OXC) switches currently use an architecture in which regenerators and transceivers have pre-assigned and fixed directionality. However, technology is evolving to enable new OXC architectures in which the directionality of regenerators and transceivers can be dynamically assigned on demand for each connection that requires regeneration. We have performed detailed analytical and simulation studies to compare the two architectures. The analytical study is applicable to a single node and is very useful in providing intuitive insights into the two alternative architectures. The simulation study is based on a realistic network topology consisting of 53 nodes. The simulation study was carried out using NIST’s updated GMPLS Lightwave Agile Switching Simulator (GLASS) tool. The GLASS tool was significantly enhanced over its previous version in the course of this study. We report extensive results on comparison of the two OXC architectures in a re...
