摘要：

Broadband ISDN (B-ISDN) offers new facilities for video transmission. Asynchronous Transfer Mode (ATM) is suitable for integrating different types of services (data, voice,video) and ensures a new flexibility of the network relatively to traffic control and resources utilization. As a drawback delays and losses of packets are to be considered. A basic step to valutate such performance parameters is the estimation of models of packet production of each data source contending network resources. In this paper a model, not strictly frame buffered, accounting of the bit rate generated by a compressed video source is proposed and its validity is assessed by fitting it to true bit rate data from a DCT video coder. Simulations of the modeled video source as input to an ATM multiplexer, together with other kinds of traffics, are presented to investigate the performance of the network.
