Optical burst switching is a promising solution for all optical WDM networks It combines the benefits of optical packet switching and wavelength routing while taking into account the limitations of current all optical technology In OBS the user data is collected at the edge of the network, sorted based on destination address,and grouped into variable sized bursts Prior to transmitting a burst, a control packet is created and immediately send toward the destination in order to setup a buffer less optical path for its corresponding burst After an offset delay time, the data burst itself is transmitted without waiting for positive acknowledgement from the destination node the OBS framework has been widely studied in the past few years because it achieves high traffic throughput and high resource utilization .In this paper we present in a systematic way the main objectives of OBS design parameters and the solutions that have been proposed
