Guidelines for Connection-Level Performance Simulation of Optical Networks

Free registration required

Executive Summary

Simulation of optical networks that set up and tear down connections dynamically involves defining the network and traffic model as well as configuring the simulator itself, to investigate a researched method, for example, a novel routing scheme. Because of interdependences in the overall constellation, a coordinated setting is necessary to obtain meaningful performance results such as estimates on the blocking probability. This paper develops a framework for connection-level simulation along with several suggestions on further simulation enhancements. ONE of the appealing options of future optical networks is the operation with dynamic connections. The connections could be opaque or transparent lightpaths. Authors think of "dynamic" as changing over time and these time changes occur within the order of weeks or shorter.
