Experiments with dynamic multiplexing and UPC renegotiation for video over ATM

In this paper we present an experimental approach for QoS-aware and bandwidth-efficiency transmission of multimedia sources over ATM networks. VBR video sources are statistically multiplexed at the application level and the UPC parameters of a single connection for the aggregate traffic are dynamically renegotiated with the network during the session lifetime. A statistical multiplexer computes the required ban...
