Abstract

Optical burst switching (OBS) is the most promising technique to explore the huge bandwidth offered by the optical fiber. In OBS network sender does not wait for an acknowledgment of path reservation and uses only one-way reservation for data transmission. In spite of being very promising this one-way reservation policy of OBS technology may create contention during data transmission. Contention in the network leads to loss of packets as a result the efficiency of the optical network deteriorates. To achieve optimum performance of an OBS network it is essential to employ proper contention resolution techniques. This article investigates the contention resolution capability of segmentation based dropping scheme for JET based OBS network. Performances of three different segmentation burst dropping policies such as head dropping; tail dropping and modified tail dropping are discussed and compared for above mentioned networks. Both finite and infinite input cases are considered here.
