Quality of service based transport architecture using XTP

The RACE 2060 project CIO (Coordination, Implementation and Operation) uses a quality of service (QoS) based multimedia architecture supported by XTP (Xpress Transfer Protocol) XTP covers the OSI transport and network layer and is designed for high-speed communication. It has flexible mechanisms, such as connection-oriented mechanisms and selective retransmission, for QoS provision of multimedia and distributed applications in heterogeneous internetwork environments. Combining the flexibility of XTP's mechanisms with service- and QoS-dependent resource-reservation schemes, the authors discuss the concepts of the XTP prototype implementation, which is providing resource control especially on ATM networks. The authors also compare related multimedia platforms, like the Internet Stream (ST-II) protocol, which they use in the BERKOM project.<
