Computing loss probability for dynamic traffic grooming in optical networks with wavelength conversion

Abstract

With the huge capacity, wavelength division multiplexing (WDM) optical networks are predominantly used as the transport infrastructure to carry inter-domain traffic for client networks. Traffic grooming refers to the aggregation of low-speed client traffic flows onto high-capacity optical connections, to achieve cost-effective traffic transport. In this paper, we propose a route segment technique to efficiently compute the client traffic blocking probability in dynamic traffic grooming, where client traffic randomly arrives/departs. In our experiments, the blocking probabilities computed by this technique closely match the results obtained by simulations.
