A Performance Study of an Optical Burst Switched Network With Dynamic Simultaneous Link Possesion

In Optical Burst Switched (OBS) networks a burst may occupy a wavelength on one or more links as it travels through the network. In the literature, OBS networks have been analyzed assuming that each burst occupies only a wavelength on a single link. This paper investigates to study analytically the performance of an OBS network with a mixture of different size bursts. The short bursts occupy a wavelength on a single link while the long bursts occupy simultaneously wavelengths on multiple consecutive links. The authors develop a queuing network, which models simultaneous link possession, and they calculate analytically the end-to-end burst loss probabilities over a path in the OBS network.
