This paper proposes a new destination initiated (i.e., backward) reservation protocol for lightpath establishment in wavelength division multiplexed (WDM) optical networks. This protocol, named Intelligent Backward Reservation Protocol (iBRP), initially attempts a quick forward reservation using a definite wavelength selected intelligently, failing which it becomes standard BRP. If the initial direct attempt succeeds, BRP is not invoked at all, making iBRP very quick sometimes. The small pre-emptive forward reservation in iBRP provides enhanced efficiency and low setup time (at the cost of slight increase in overall control overhead on average), compared to standard BRP. Simulation analyses of iBRP along with typical variations of BRP and FRP reveal the marginally better performance of iBRP than others even at very high load.
