Optical Burst Switching (OBS) is assumed to be the technology of the next generation. In OBS, data is transported in the form of optical burst. In general, the size of the burst can be of any length with minimum of one packet duration. Till date, the size of the burst cannot be estimated in advance, therefore, OBS relies on the fact that arriving burst at any node will either be served or deflected to some other node and after some more slot, it will re-appear on the same node. This mechanism is known as deflection of packet. In this paper, we have presented an optical node architecture, where optical burst can be stored using the fiber delay lines, thus the buffering of burst will reduce average latency, as well as will improve burst error probability (BER).
