Interworking unit function for real time delivery and control of multimedia service between ATM and internet

摘要

We propose the middleMEN(middlement for Multimedia EN vironment) platform for realizing the interworking between the ATM network and the Internet. The middleMEN consists of the interworking unit and the service broker to provide seamless multimedia service between the ATM network and the Internet. This paper proposes the function of the interworking unit of the middleMEN for a real time delivery and control of multimedia service. For a real-time delivery of multimedia service between the ATM network and the Internet, the interworking unit of the middleMEN does the following functions: protocol conversion, and bandwidth adaptation (data format conversion, and bit-rate control). The interworking unit of the middleMEN converts the protocols of the ATM network to the Internet protocols for real-tiem delivery. Also, it does data format conversion, and bit-rate control to overcome bandwidth difference between the ATM network and the Internet.
