Abstract :
This paper provides new loss models for an OCS/OBS optical hybrid switch. Exact results for the blocking probability based on an analysis, of a 3-dimension state-space Markov chain is derived when circuits are given preemptive priority over bursts and are allowed to wait a certain amount of time if all wavelengths are busy in the desired output link. Because it is difficult to-exactly compute the blocking probability in realistic scenarios, we derive a. computationally scalable approximation for the blocking probability reducing the 3-dimension state space into a single dimension
