Analytical performance study of multiple packets reception capabilities for network interfaces in WDM LANs

The multiple packets reception by a station network interface in WDM networks is explored in this study. Especially, we assume a WDM LAN of passive star topology which uses the MCA for the control information exchange. The station network interface includes three tunable receivers in order to face the packets rejection at destination due to the receiver conflicts. An efficient WDMA protocol is adopted that significantly reduces the control packets collisions, while it totally avoids the data packets loss over the data channels. The system performance measures are analytically derived based on a Markovian model. Numerical results are studied for diverse numbers of control channels. Comparative results study proves the performance improvement that the proposed network interface configuration provides, as compared to the single receiver per station case.
