Analysis of restoration and protection in optical network with simulation framework

Krishan Kumar , Amit Kumar Garg

Survivability is one of the most important requirements of optical networks. As optical networks are prone to component failures and carry a large volume of traffic, maintaining a high level of service availability is an important issue. In this paper, existing restoration methods proposed for optical network are critically analysed. A Net2Plan tool is presented, its features and how effectively a problem can be framed and existing and modified algorithms can be implemented on resilience simulation
