Optical Burst Switching (OBS) é uma das tecnologias de comutação mais promissoras para redes ópticas de próxima geração. Como aplicações sensíveis a atrasos, como Voz sobre IP (VoIP), tornaram-se recentemente populares, as redes OBS devem garantir requisitos rigorosos de Qualidade de Serviço (QoS) para tais aplicações. Assim, este artigo propõe um esquema Adaptive Loss-aware Flow Control (ALFC), que decide adaptativamente o tempo de deslocamento do burst com base nas informações de taxa de perda entregues pelos nós principais para atribuir uma alta prioridade ao tráfego de aplicativos sensíveis a atrasos. O esquema ALFC proposto também controla os limites superiores dos fatores que induzem atraso e jitter para garantir os requisitos de atraso e jitter do tráfego de aplicações sensíveis a atrasos. Além disso, um método de piggybacking usado no esquema proposto acelera a garantia dos requisitos de perda, atraso e jitter porque o tempo de resposta para controle de fluxo pode ser extremamente reduzido em até um quarto do tempo de ida e volta (RTT) em média, minimizando ao mesmo tempo o sobrecarga de sinalização. Os resultados da simulação mostram que nosso mecanismo pode garantir 10-3 taxa de perda sob qualquer carga de tráfego, oferecendo níveis satisfatórios de atraso e jitter para aplicações sensíveis a atrasos.

Abstract: Optical Burst Switching (OBS) is one of the most promising switching technologies for next generation optical networks. As delay-sensitive applications such as Voice-over-IP (VoIP) have recently become popular, OBS networks should guarantee stringent Quality of Service (QoS) requirements for such applications. Thus, this paper proposes an Adaptive Loss-aware Flow Control (ALFC) scheme, which adaptively decides on the burst offset time based on loss-rate information delivered from core nodes for assigning a high priority to delay-sensitive application traffic. The proposed ALFC scheme also controls the upper-bounds of the factors inducing delay and jitter for guaranteeing the delay and jitter requirements of delay-sensitive application traffic. Moreover, a piggybacking method used in the proposed scheme accelerates the guarantee of the loss, delay, and jitter requirements because the response time for flow control can be extremely reduced up to a quarter of the Round Trip Time (RTT) on average while minimizing the signaling overhead. Simulation results show that our mechanism can guarantee a 10-3 loss-rate under any traffic load while offering satisfactory levels of delay and jitter for delay-sensitive applications.
