Um Serviço Ativo de Distribuição de Video Multiponto

Paulo Andre da Silva GonçalvesJose Ferreira de RezendeOtto Carlos Muniz Bandeira Duarte

This paper proposes a service for multicast video distribution based on the active network paradigm. Active nodes can provide soft-state and perform customized computations on a per-user or per-application basis. These functionalities allow the deployment of an efHcient and flexible service that can dynamically adjusts itself to the bandwidth availability. The source learns about the supported transmission rate of the video by receiving feedback messages from receivers. A fusion mechanism isused to prevent feedback-message implosion. Simulation results show that a capsule filtering levei of 96% can be reached by using the fusion mechanism.
