Design and performance evaluation of WDMA protocols for high-speed optical network

In this paper, we propose two types of WDMA protocol for multi-wavelength optical networks that have a dedicated control channel. Protocol type I is designed for the case that the number of nimislots is less than the number of nodes (La${\ge}$M). Proposed protocols employ the aging scheme to guarantee a fairness in the process of channel allocation. The perfomrance of proposed protocols are evaluated in terms of throughput and delay with variations in offered load. Simulation results show that the proposed protocols have superior performance to conventional protocols.
