RESUMO

In this work the Anticipated Traffic Allocation Protocol (ATAP) for Video sources in ATM (Asynchronous Transfer Mode) networks is analyzed. The ATAP is an anticipated bandwidth allocation proposal for periodic variable bit rate (VBR) sources, which has the ability to handle application with QoS requirements equivalent to CBR (Costant Bit Rate) class services with the advantage of higher statistical gain. In order to achieve this, ATAP is based on traffic admission control at its input local node and on bandwidth source requirement prediction which done dinamically though resource reservation provided by the fast reservation protocols. In the evaluation models we used sequences from different video encoders (H.261 and TV/HDTV) combined with fast reservation protocols. FRP/DT - Fast Reservation Protocol with Delayed Transmission and FBM - Fast Buffer Management). Simulation results are presented and analyzed.
