The technologies and standardization of ATM, Internet and satellites have been developed independently. Each discipline has its own QoS (Quality of Service) problems. These problems are compounded when systems consider combinations of all three disciplines. In this presentation the incompatibilities and challenge issues are first addressed. Next, the QoS problems are identified. Third, potential solutions and opportunities are highlighted.
For ATM, the discussion will center on the new QoS methods of ATM cell based transmission. Both the simulation and hardware (semiconductor chip sets) results provide the optimal solutions. These solutions are fully compatible with ITU-T and the ATM Forum Specifications.
For Internet, in addition to reliability it will be brought forth that transmission delay, efficiency, signalling speed, and channel utilization of the TCP/IP can be significantly improved. These improvements are obtained without a single bit change from the TCP/IP standard formats, which have been established by the Internet Engineering Task Force (IETF). ATM over IP is within reach.
For satellite communications, the existing international standards are recommended to be changed in order to be truely compatible with ATM and Internet with sufficent justifications.
