Given the current state of the technology, the Optical Burst Switched (OBS) network is the most practical all-optical architecture. The user data is transmitted in variable size data packets, called bursts, which travel as an optical signal along the entire route. The control information for each burst is transmitted prior to its corresponding burst and it is electronically processed at each hop along the route. In this paper, the authors have classify different optical transport technology & shows how burst assembly will be carried out, moreover they define challenges faced at practical implementation of OBS including burst contention & proposed its unique solution at the edge node.
