A WDM control architecture and destination conflicts analysis

The well-known Single-hop Wavelength division multiplexing (WDM) networks using passive star topology, provide direct connection between the source and the destination of a data packet but require some pretransmission coordination between the stations over a control channel. Since the electronic processing bottleneck that the single control channel architecture introduces is high, we propose a new WDM control architecture to overcome this problem. Also, we develop and analyse a queueing model of the network in order to obtain the queue length distribution and loss probabilities at the receiving sides of the stations. A rigourous method is developed to examine the receiver collision phenomenon and to evaluate the performance reduction due to the finite number of tuneable receivers at each station and finite population.
