A new network architecture which uses several wavelengths as control channels for co‐ordination of packet transmissions on data channels for single‐hop WDMA networks and passive star topology is introduced in this paper. The presented multiwavelength control architecture distributes control information over the total control channels and in conjunction with a suitable network interface, reduces the headers electronic processing bottleneck at each end station. Also, the access schemes decrease the contention on data channels by avoiding part of the data channel collision. Some cases of multiple access protocols for asynchronous and synchronous (re)transmission categories are suggested. The proposed schemes adopt the slotted ALOHA protocol for the access to control and data multichannel systems in which the data packets transmission starts immediately after the control packets transmission. An analytic model is developed and analysed for performance measures evaluation based on Poisson approximations statistics and a finite population. The effect of receiver collision is analysed and estimated by the average rejection probability at destination. Also, numerical results are discussed for various numbers of control and data channels.
