Abstract:
Dedicated path protection is a robust and efficient way to increase the resiliency of a telecommunication network. Two variants of a bi-criteria dedicated path protection model for wavelength division multiplexing (WDM) networks in a dynamic traffic scenario, are presented. The proposed routing approach is based on a bi-criteria optimization model for the calculation of disjoint lightpath pairs in WDM networks with dedicated protection. A performance analysis study of the proposed routing method considering two different metric pairs as objective functions and using an exact resolution approach, in a reference test network, is highlighted. The presented simulation results show the potential advantages of this approach when compared with single criteria optimization approaches.
