Abstract

Wavelength division multiple access (WDMA) as a technique for achieving broadband communications in the future optical access network is introduced. This is followed by a brief review of WDMA protocol strategies which have been proposed in order to facilitate high capacity network throughput. In particular, new efficient WDMA demand assignment protocols, suitable for operation in such a high speed environment, are presented and their performance investigated using discrete event computer simulation techniques. It is demonstrated that protocols of this type could provide for broadband communications in the optical access network. Under symmetric traffic loading, the WDMA protocol performances are shown to exhibit an improvement over the single channel case which is particularly significant at higher transmission rates. It is then demonstrated that the WDMA protocol performances are much less sensitive to the degradation caused by asymmetric traffic loads resulting in a substantial improvement in the maximum throughput achievable. Hence, the potential capacity of this broadband strategy for the optical access network is explored.
