Paper Abstract

This paper describes an inter-domain path control system for large-scale photonic networks, especially considering applicability to multiple carrier domain networks. The overall architecture of multi-domain optical network control system is reviewed. Our system employs PCE (Path Computation Element) based routing model and utilizes maximum flow information in path computation and Path Key scheme in signaling, which improve the load-balancing and the confidentiality of the inside information for the route computation and the path provisioning among different carriers. The measured performance results for inter-domain path computation and path setups using global optimization scheme is also provided. It includes estimation of the path provisioning time at the network scale dependency with the route computation time and the signaling time. As a result, its applicability to a 1000-node scale photonic network is shown.
