Design, performance and wavelength assignment of a wavelength division multiaccess protocol for optical fibre ring networks

This paper presents a multiaccess strategy for use over optical fibre ring networks employing two counter rotating rings, and using wavelength divisio n multiplexing. Transmitters employ tunable lasers, while receivers employ one or more fixed wavelength filters. The paper introduces an algorithm for the optimal assignment of the receivers to the channels, such that the pos sibility of finding an unused channel leading to a certain receiver is maxi mized. The paper contains a performance study of the network protocol. (C) 1999 Elsevier Science B.V. All rights reserved.
