Given a logical topology and a physical topology , the survivable logical topology design problem in an IP-over-WDM optical network is to map the logical links into lightpaths in such that remains connected after the failure of any edge in. In view of its fundamental nature and its practical importance, this problem has received considerable attention in(More)
—The survivable logical topology mapping problem in an IP-over-WDM optical network is to map each link (u, v) in the logical topology (at the IP layer) into a lightpath between the nodes u and v in the physical topology (at the optical layer) such that failure of a physical link does not cause the logical topology to become disconnected.

High speed all optical network is a viable option to satisfy the exponential growth of internet usage in the recent years. Optical networks offer very high bit rates and, by employing technologies like internet protocol over wavelength division multiplex-ing (IP-over-WDM), these high bit rates can be effectively utilized. However, failure of a network(More)
Wavelength Division Multiplexing (WDM) can increase the carrying capacity of an optical network without laying additional fibers. However, a disruption in such a high speed and high capacity network can quickly impact the entire network. A fast protection and restoration recovery mechanism is needed to provide uninterrupted data delivery. Implementing IP(More)
