Abstract :
This paper proposes a centralized control architecture and a time-slot assignment procedure for time-slotted optical burst switched (OBS) networks in which ingress OBS nodes request time-slots necessary to transmit optical bursts, and a centralized control node makes a reply according to the slot-competition result. Our scheme attempts to improve burst contention resolution and optical channel utilization. Analysis and simulation results show that the channel utilization of the time-slotted OBS network is improved markedly at the expense of ingress buffering delay
