Abstract

The transport control protocol (TCP) is one of the most heavily used protocols on the Internet, offering a reliable, connection oriented transport service. However, the quality of service (QoS) provided by the TCP protocol deteriorates when it is used over satellite IP networks. With the increased usage of Internet applications by the military in remote geographical regions, there is an increased need to address some of the shortcomings of TCP performance in satellite IP networks. In this research we describe our efforts at designing and testing a performance enhancing proxy (PEP) that can be used improve the QoS provided by the TCP service in large latency networks. We also show how one can use such a proxy to create a new transport service similar to the Available Bit Rate (ABR) service provided by ATM networks without needing ATM infrastructure, this new service offers a connection oriented, reliable, best effort transport service with minimal queuing delay, jitter and throughput variation.
