—In this letter, we propose a computational model for calculating blocking probabilities of multifiber wavelength division multiplexing (WDM) optical networks. We first derive the blocking probability of a fiber based on a Markov chain, from which the blocking probability of a link is derived by means of conditional probabilities. The blocking probability(More)
networks are part of the telecommunications infrastructure that connect individual subscribers to the service provider's central office (CO) over public ground. They are cost prohibitive and have consistently been regarded as the bottleneck , primarily because the ever-growing demand for higher bandwidth is beyond the supported levels of the widely deployed(More)
We present features of next generation SONET, focusing particularly on path management. Factors such as QoS metrics and path protection are keys to realize automatic and dynamic path management. Two algorithms (the sequential algorithm and the parallel algorithm) to provide QoS and protection path in SONET are proposed and discussed in details. They balance(More)
