Abstract

We study the effect of multiple fibers in circuit-switched all-optical wavelength-routing networks. A new analytical model-the multifiber link-load correlation (MLLC) model-is developed to evaluate the blocking performance of such networks. To our knowledge, the MLLC model is the first model that takes the link-load correlation into account in multifiber WDM networks. We show that the MLLC model is accurate for a variety of network topologies by comparing the analytical results to simulation results. We observed that a small number of fibers are sufficient to guarantee high network performance in multifiber WDM networks.
