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. In this paper, we 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. We develop a queueing network, which models simultaneous link possession, and we calculate analytically the end-to-end burst loss probabilities over a path in the OBS network. Our results indicate that having a mix of various size bursts can greatly effect the burst loss probabilities in the network.
