Performance analysis of a WDMA protocol with a multiple tunable receivers node architecture for high-speed optical fiber lans

摘要

A synchronous transmission WDMA protocol for high-speed optical fiber LANs of passive star topology is studied in this paper. The packet rejection at destination, referred as receiver collision, is extensively examined. A network interface with more than one tunable receivers per destination station is considered. This means that each station is capable of receiving more than one data packets during a time frame. The presented WDMA protocol expands previous studies about the receiver collision phenomenon that assume a single tunable receiver per station, while it provides an analytical framework about its effect on the total network performance. The average throughput and rejection probability are analytically derived, while the bandwidth utilization improvement provided by the use of the multiple tunable receivers station interface is estimated. The analysis considers Poisson arrivals and finite station population. Numerical results are comparatively studied for various numbers of data channels and stations.
