Real time Delivery and Control Mechanism of Multi een ATM Network and Internet

This paper proposes the middleMEN(midd1emen for Multimedia Environment) approach for a real time delivery and control mechanism of multimedia service between the ATM network and the internet. MiddleMEN consists of the interworking unit and the service broker to provide seamless multimedia service between the ATM network and the internet. For a real-time delivery of multimedia service between the ATM network and the internet, the intenvorking unit of the middleMEN does the following functions: protocol conversion, data format conversion, traffic monitoring and bit-rate control. The interworking unit of the middleMEN converts the protocols of the ATM network to the internet protocols for real-time delivery. Also, it does data format conversion, traffic monitoring and bit-rate control to overcome bandwidth difference between the ATM network and the internet.
