Xpress transfer protocol over the BERKOM B-ISDN network

The Xpress Transfer Protocol (XTP) is a typical example of a protocol with new mechanisms and functionality specifically designed for new high-speed network environments and applications. XTP can provide the full range of services needed to support distributed processing systems. A software implementation of XTP has been completed to run over the BERKOM broadband ISDN. The software architecture of the implementation is presented. Performance measurements of XTP over the BERKOM network are reported and compared to those of TCP/IP protocol. XTP has been found to perform about as well as and in some situations better than TCP/IP.
