Abstract :
The all-photonic overlaid star network (APOSN) provides a simple architecture for high-speed backbone networks using available optical technologies. We consider in this paper a distributed signaling and scheduling protocol to enable prompt responding and flexible control of traffic demands. A contention-based approach is used for bandwidth allocation, and there is no coordination among the edge switches and the edge switches transmit traffic to the egress switches via the core switch at any time. Two schemes are considered here: the optical burst switching (OBS) operation that is random, as opposed to the more orderly scheduled distributed TDM (DTDM). By studying the operation ranges of various typical parameters for these two schemes as well as their variants, we are able to provide performance tradeoffs and insights into the effect of system parameter settings
