Abstract: The paper discusses the performance of access strategies for all‐optical packet networks based on a WDM multichannel ring topology with a number of synchronized slotted channels; nodes are equipped with one tunable receiver, one tunable transmitter, a variable number of delay lines and optical switches, and a FIFO transmission queue. Several access strategies based on local status information are described and compared, taking as performance indices packet loss probability, and maximum achievable throughput. We show that, among the considered proposals, the most efficient is a simple strategy that guarantees loss‐free transmission.
