WDMA-local lightwave networks with an efficient control channels architecture for electronic processing bottleneck reduction

A new network architecture which uses several wavelengths as control channels for coordination of packet transmissions on the data channels for single-hop WDMA networks and passive star topology is introduced. The control information are distributed over the total control channels reducing the electronic processing bottleneck at one of the end stations. Time is divided into fixed size cycles. The proposed schemes adopt the slotted ALOHA protocol for the control and data multichannel systems and differ in the adopted policy for data packet transmission. An analytical model is developed for the performance measures evaluation based on Poisson approximations statistics and an infinite population. Numerical results are also discussed for the various control and data channels.
