Abstract

In optical networks, each single lightpath can offer huge bandwidth to carry the client traffic. In many cases, the clients require the optical network to provide the survivability of the carried traffic. Hence how to route the working and protection paths to better utilize the wavelength resource is an important challenge for service providers. In this paper, we propose a joint lightpath routing approach to select the working and protection paths for the dynamic traffic. The proposed routing approach attempts to perform individual optimization on the path selection for each call request. The performance of the joint lightpath routing approach has been examined against the traditional lightpath routing approach.
