Este artigo propõe um protocolo de controle de acesso ao meio (MAC) para redes de acoplador estrela WDM de salto único, nas quais o número de estações é maior que o número de canais e as estações possuem distâncias arbitrárias até o acoplador estrela. O protocolo proposto possui um canal de controle para reserva de slots de canais de dados e diversos canais de dados que são utilizados para transmissão de tráfego. Este artigo também sugere um esquema que realiza balanceamento de carga entre canais de dados para padrões de tráfego arbitrários entre estações. Uma vez que este esquema de balanceamento de carga diminui a influência que os padrões de tráfego têm no desempenho do protocolo MAC proposto, o sistema proposto é apropriado para sistemas que possuem intensidade de tráfego assimétrica entre estações. O throughput e o atraso médio das mensagens do protocolo MAC são analisados usando um processo Markov de tempo discreto e uma fila D/G/1 com chegadas em lote. Os resultados numéricos mostram que o desempenho melhora à medida que o comprimento da mensagem aumenta, o atraso máximo de propagação de ida e volta diminui e o número de canais de dados aumenta.

Abstract: This paper proposes a medium access control (MAC) protocol for single-hop WDM star-coupler networks, in which the number of stations is larger than the number of channels and the stations have arbitrary distances to the star coupler. The proposed protocol has one control channel for reserving the slots of data channels and several data channels which are used to transmit traffic. This paper also suggests a scheme that accomplishes load balancing among data channels for arbitrary traffic patterns between stations. Since this load balancing scheme diminishes an influence that traffic patterns have on the performance of the proposed MAC protocol, the proposed system is appropriate for systems which have asymmetric traffic intensity between stations. Throughput and mean message delay of the MAC protocol are analyzed using a discrete time Markov process and a D/G/1 queue with batch arrivals. The numerical results show that the performance is improved as the message length increases, the maximum round-trip propagation delay decreases, and the number of data channels increases.

The proposed protocol has one control channel for reserving the slots of data channels and several data channels which are used to transmit traffic.

Since this load balancing scheme diminishes an influence that traffic patterns have on the performance of the proposed MAC protocol, the proposed system is appropriate for systems which have asymmetric traffic intensity between stations. Throughput and mean message delay of the MAC protocol are analyzed using a discrete time Markov process and a D/G/1 queue with batch arrivals. The numerical results show that the performance is improved as the message length increases, the maximum round-trip propagation delay decreases, and the number of data channels increases.
