Abstract :
A number of protocols for WDM (Wavelength Division Multiplexing) star networks have been proposed. However, the area of real-time protocols for these networks is quite unexplored. In this paper, a real-time protocol, based on TDM (Time Division Multiplexing), for a fiber-optic star network is presented. By the use of WDM, multiple Gb/s channels are achieved. Services for both guarantee-seeking messages and best-effort messages are supported for single destination, multicast, and broadcast transmission. Slot reservation can be used to increase the time-deterministic bandwidth, while still having an efficient bandwidth utilization due to a simple slot release method. The deterministic properties of the protocol are analyzed and simulation results presented
