A Burst Assembly Algorithm in Optical Burst Switching Networks

Not Accessible

Optical WDM network evolves from the traditional IP/ATM/SDH/WDM to IP over WDM network, by eliminating the ATM switching layer and SDH transport layer. In this situation, the current use of the wavelength-routing mechanism for carrying bursty IP traffic will suffer from various drawbacks associated with circuit-switched networks. Wavelength routing results in a low bandwidth utilization if the traffic is bursty and provides a low granularity. But optical packet switching technology is still facing significant cost and technological barriers because of optical Random Access Memory buffer problem and slow switching speed.1 Optical burst switching attracts the spot light because it compromises IPoW circuit switching and pure optical packet switching with limited use of optical buffer. In this paper we propose a new burst assembly algorithm using hysterisis characteristics in the queueing model in the edge node of optical burst switching network. We first discuss the functional model.
