OPTICAL MESH NETWORK MODELING: SIMULATION AND ANALYSIS OF RESTORATION PERFORMANCE

Abstract

Optical mesh networks using intelligent optical switches are the choice for the next generation optical core. Mesh networks supporting shared mesh restoration provide many advantages over ring networks and can be designed for fast and guaranteed recovery from single link or node failures. The restoration latency performance depends on numerous factors that can have an impact on service level agreements. Network deployment is tedious and making changes after equipment is deployed can be very expensive and time consuming. Thus, it is important to predict restoration performance before deployment and make changes to network design if necessary. Hence, modeling, simulation and analysis of shared mesh restoration performance is an important part of network design and deployment. In this paper, we present two approaches to restoration performance modeling of core mesh networks, namely simulation and analysis, and how they are used as part of the network design and deployment process. 1.
