Analysis and Optimisation of CODE Protocols

European Space Agency (ESA) (TE)

This project investigated the performance of TCP/IP over a VSAT LAN-interconnection system, including successful demonstration of the system with other European sites. This project was a part of the European Co-operative Data Environment (CODE) network. Aberdeen carried out a detailed analysis of the performance of the TCP/IP protocols, including well known application protocols such as RPC, NFS, X-windows, ftp and telnet. Data from simulation was supplemented with measurements made over live satellite links using the CODE VSAT terminals at Aberdeen University.It has shown that these protocols provide performance comparable to that observed on most European terrestrial connections operating at similar speeds, but that optimisation of the protocols is possible by a careful analysis and that very substantial improvements in performance may result from proper selection of key parameters.
