Os avanços nos serviços que utilizam a Internet actual significam que haverá uma procura crescente de Vídeo on Demand (VoD) na Internet num futuro próximo. Contudo, devido às características de melhor esforço da Internet, é importante suprimir a degradação da qualidade da comunicação causada pela queda de pacotes quando o tráfego da Internet está congestionado. Este artigo enfoca a transmissão MPEG pela Internet, e mecanismos de controle adequados são estabelecidos para uma melhoria aceitável da Qualidade de Serviço (QoS) através de avaliação detalhada. Os pacotes são classificados usando um esquema baseado em quadros. O servidor aplica o esquema de controle ponta a ponta proposto e embaralha a ordem dos pacotes para evitar a queda em rajadas, podendo omitir pacotes selecionados pertencentes a determinados quadros antes do encaminhamento. Nos roteadores intermediários, os pacotes transferidos são transmitidos de acordo com o agendamento Round Robin (RR) ou Weighted Round Robin (WRR) e são descartados estatisticamente usando Random Early Detection (RED) seletivo correspondente aos atributos do quadro quando há congestionamento. Avaliamos o desempenho proposto do método de transmissão usando simulações computacionais e medições empíricas de qualidade de imagem. Os resultados mostram que quando o volume de tráfego não pode ser estimado nos roteadores intermediários, o uso combinado de RR, embaralhamento e RED condicional é eficaz, e quando o volume de tráfego pode ser estimado, a combinação de WRR, controle de taxa e RED é eficaz.

Abstract: The advances in services using the present Internet mean that there will be increasing demand for Video on Demand (VoD) on the Internet in the near future. However, because of the best-effort characteristics of the Internet, it is important to suppress the degradation of communication quality caused by packet dropping when Internet traffic is congested. This paper focuses on MPEG transmission over the Internet, and suitable control mechanisms are established for an acceptable Quality of Service (QoS) improvement through detailed evaluation. Packets are classified using a frame-based scheme. The server applies the proposed End-to-End control scheme and shuffles the order of packets to avoid burst dropping, and may omit selected packets belonging to certain frames prior to forwarding. At the intermediate routers, transferred packets are transmitted according to Round Robin (RR) or Weighted Round Robin (WRR) scheduling, and are dropped statistically using selective Random Early Detection (RED) corresponding to frame attributes when there is congestion. We evaluate the proposed performance of transmission method using both computer simulations and empirical measurements of picture quality. The results show that when the traffic volume cannot be estimated in the intermediate routers, the combined use of RR, shuffling and conditional RED is effective, and when the traffic volume can be estimated, the combination of WRR, rate control and RED is effective.
