✦ Synopsis

This paper presents a new token-based channel access protocol for wavelength division multiplexed optically interconnected multiprocessors. Our empirical study of access protocols based on slotted time division multiplexed data and control channels reveals that such protocols typically suffer from excessive slot synchronization latency due to static slot preallocation. The proposed token-based time division multiple access protocol minimizes latency by allowing dynamic allocation of slots to use channels efficiently. Simulation results indicate that the proposed scheme can significantly increase the performance for protocols based on preallocation and also those based on preallocation-controlled reservation of multiple channels. 2000
