Description: Optical burst switching (OBS) is an optical networking technique that allows dynamic sub-wavelength switching of data. OBS is viewed as a compromise between the yet unfeasible full optical packet switching (OPS) and the mostly static optical circuit switching (OCS). It differs these paradigms because OBS control information is sent separately in a reserved optical channel and in advance of the data payload. These control signals can then be processed electronically to allow the timely setup of an optical light path to transport the soon-to-arrive payload. This is known as delayed reservation.-Optical burst switching (OBS) is an optical networking technique that allows dynamic sub-wavelength switching of data.

Description: Optical Burst Switching (OBS) network is seen as a promising solution as it directly transports Internet-Protocol over Wavelength Division Multiplexing (IP over WDM) networks. OBS network uses a one-way resource reservation mechanism to set up the resources for each data burst transmission. Therefore, the performance of OBS networks depend on contention resolution strategies to reach acceptable levels for bandwidth utilization efficiency. This paper proposes the use of burst segmentation as a proactive contention resolution technique at ingress nodes of OBS network as well as reactive contention resolution policy at core nodes for reducing the probability of burst drop in the network in order to increase the performance of the network. -Optical Burst Switching (OBS) network is seen as a promising solution as it directly transports Internet-Protocol over Wavelength Division Multiplexing (IP over WDM) networks.
