A service interworking unit for accommodating multimedia communications with quality of service between ATM and Internet

Much has been written about the potential of quality of service (QoS) and the Internet. The integration of voice, data and video services modified the target of networking technologies. Networks must have some capabilities for integration of various services and also for QoS support as required by each of those services. The EAGIS (Efficient ATM Gateway for real time Internet Service) consists of the interworking unit and the service broker to provide seamless multimedia service between the ATM network and the Internet. The authors explain the design of the interworking unit of the EAGIS. For a real time delivery of multimedia service between the ATM network and the Internet, the interworking unit of the EAGIS performs the following functions: protocol conversion, data format conversion, traffic monitoring and bit-rate control. It 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
