✦ Synopsis
In this paper we study a single-hop WDM network for passive star topology, based on a new network architecture which uses several wavelengths as control channels with an appropriate Network Interface Unit at each station for coordination of packet transmissions on the data channels referred to as Multichannel Control Architecture (MCA). With MCA, control informations are distributed over the total control channels and in conjunction with the suitable NIU reduces the headers electronic processing bottleneck at each end station. We propose a multiple access protocol which operates asynchronously, i.e data channels are not slotted. The proposed scheme adopts the ALOHA protocol for the access to MCA and data channels. Analytic model is developed and analysed for performance measures evaluation based on Poisson approximations statistics of both the in®nite and ®nite population. Numerical results are discussed for various number of control and data channels. The effect of receiver collisions is analysed and estimated by the average rejection probabilities at destination.
