Contention resolution using burst segmentation in Optical Burst Switching.

One of the key problems hindering the realization of optical burst switching (OBS) technology in the core networks isthe losses due to contention among the bursts at the core nodes. Handling contention losses is a unique problem in bufferless OBS networks which cannot be handled similar to congestion in the traditional networks.
Various schemes such as optical buffering, wavelength conversion, burst segmentation (BS), and deflection routing are proposed for contention resolution in the literature. The Burst Segmentation scheme avoids the loss of entire burst and helps in the recovery of at least some packets in a burst and can reduce the packet loss probability by a significant extent.
