Abstract(in English) For effectively utilizing the WDM network, OBS (Optical Burst Switching) where the wavelengths are reserved on demand basis is considered. To reduce the overhead time, the high-speed processing of the signaling message at each hop is imperative. However, conventional electronic processing are not fast enough and will eventually become a bottleneck as the bit rate of data link goes higher. To reduce the overhead time in OBS network, we propose an OC-TAG (Optical Code based Tell-And-Go) protocol for variable length of burst with no buffering, and fast burst transfer over the WDM network. The optical-code based processing is introduced for handling the out-of-band control packet. However, the optical-code based processing is not enough for the faster data transfer since if the data transfer request is blocked, a round-trip propagation delay is necessary to retransmit the data transfer request. In order to reduce the retransmission, a contention resolution facility utilizing fiber delay lines is introduced for each node. Through computer simulations, we show the effect of introducing our architectures.
