Abstract

Proposed in this paper is an extension from a basic 2×2 contention resolving scheme to a complex N×N scheme for asynchronous variable length packets, through which contentions among multiple packets will be resolved. At first, a fast comparison algorithm is presented to build N×N all-optical contention resolution node based on 2×2 contention resolving scheme. Given the comparison algorithm, the number of basic 2×2 switching node that an N×N node demands are calculated and discussed, corresponding simulations are conducted and the packet-loss probability is tested. Moreover, further simulation is performed to evaluate the performance of the 8×8 bufferless all-optical contention resolving scheme equipped with limited-range wavelength converters (LRWCs).
