Abstract
A Broadband ATM satellite Experiment (BASE) was carried out between the Communications Research Centre, Canada and Rome Laboratory, USA during the period of May 95 to March 96. The objective of the experiment was to perform a series of tests to characterize broadband ATM satellite bearers. This document reports on the second phase of the experiment that was conducted from December 95 to March 96 over the NASA ACTS satellite(Ka-band). Tests consisted in throughput measurements of TCp over a broadband ATM satellite link as a function of Bit Error Rate (BER). The throughput performance of TCP/IP was very poor due mostly to the (bandwidth * delay) product being limited by the TCP window size implementation. The results are presented along with the influence of others factors such as the MTU size and packet size. Finally, a performance comparison with a special implementation of TCP for network with large delays (TCP-LFN) is presented.
