Abstract

In this paper, we address the problem of routing and wavelength assignment (RWA) in path-protected WDM networks with the objective of maximizing the sharing chances of wavelength links and optical-electronic-optical regenerators (OEOs) between demands, and hence, minimize the overall cost of the network. Both a Tabu Search and a Genetic Algorithm heuristics are proposed and their performance is experimentally evaluated through extensive simulation. Our simulation results confirm an average of 30% reduction in the number of OEOs compared to that required with the well-known shared-path protection scheme.
