Optical packet switching (OPS) technologies are among the most promising solutions for next generation network architectures. Resource contention resolution and Quality of Service (QoS) management mechanisms have been developed in order to remedy the lack of optical buffering and implement multi-service support in OPS networks. In this paper we propose an analytical model for the access and core nodes...
The performance of a bufferless optical packet switch, which employs shared fixed input tunable output wavelength converters, namely shared-per-wavelength, supporting quality of service is presented. The aims of the paper are both to reduce switch costs, by using simpler optical components and low complexity space switching matrices, and to provide service differentiation among packets belonging to...
Regarding the packet-switching problem, we prove that the weighed max-min fair service rates comprise the unique Nash equilibrium point of a strategic game, specifically a throughput auction based on a ldquoleast-demanding first-servedrdquo principle. We prove that a buffered crossbar switch can converge to this equilibrium with no pre-computation or internal acceleration, with either randomized or...
