Sharing user-network interfaces between networked multimedia applications

The effective use between these applications of the limited bandwidth at the User-Network Interface (UNI) has raised increasing interest from both end-system and telecommunication networks researchers. This paper addresses the structure of higher layer traffic controls at the end-systems. A session scheduling priority scheme is proposed which reflects the user specified service priority and the importance of the minimum quality. A stream level traffic control device (`stream filter´) is proposed at the end-system, which may restrain a traffic stream in response to cell level connection status. The interactive mechanism between the session scheduler and the stream filters has been investigated
