In this paper we illustrate a new methodologyfor the designof fault-tolerant logical topologiesin wavelength-routed optical networks exploiting wavelength division multiplexing, and supporting both unicastand multicast IP datagram flows. Our approach to protection and restoration generalizesthe “design protection” concepts,and relieson the dynamic capabilitiesof IP routing to re-routeIP datagrams when faults occur, thus leading to high-performancecost-effecti ve fault-tolerant logical… CONTINUE READING
