This is a Mtech thesis project on Self-healing ATM networks based on WDM,

light path technologies. Aim of the project is to design Virtual path and

Light path networks. Given a physical network along its bandwidth, it is

required to find Virtual paths, to reduce routing table entries, and to

reduce setup, switching delays. An algorithm is implemented to select best

Virtual paths. WDM is a technology, which addresses high bandwidth

requirements in optical networks. Since available numbers of frequencies

are few, it is required to find out a optimum light path network, over

Virtual path network, in order to reduce fiber cost in ATM networks. After

finding optimum virtual path network algorithm is extended to find best

light paths for a selected configuration. Self-healing considered when a

link fails and alternate virtual paths and light paths found for each

affected virtual path that shares failed physical link. USA network (28

nodes, 45 links), and ARPA networks (20 nodes, 31 links) are used in

implantation of these algorithms.
