Abstract-- Security issues and attack management in transparent WDM (Wavelength Division Multiplexing) optical networks has become of prime importance to network operators due to t...
— Rerouting is a viable and cost-effective approach to decrease the blocking probability in legacy circuit-switched networks. We study lightpath rerouting in optical WDM networks...
An efficient and general graph-theoretic model (the Wavelength-Graph (WG)) has been proposed which enables solving the static Routing and Wavelength Assignment (RWA) problems in Mu...
A network with restoration capability requires spare capacity to be used in the case of failure. Optimization of spare capacity is to find the minimum amount of spare capacity for ...
