Implementation of an Available Bit Rate Service for Satellite IP Networks using a Performance Enhancing ProxyReddy, Pavan K 29 April 2004 (has links)
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.

A Performance Analysis of TCP and STP Implementations and Proposals for New QoS Classes for TCP/IPHoll, David J. 01 May 2003 (has links)
With a new United States Army initiative to exploit commercially developed information technology, there is a heightened interest in using Internet protocols over the military's geosynchronous satellite links. TCP is the dominant Internet protocol used for reliable data exchange, but its own design limits performance when used over long delay network links such as satellites. Initially this research set out to compare TCP with another proposed protocol, the Satellite Transport Protocol (STP). However through a series of tests, we found that STP does not fulfill its claims of increased throughput over TCP and uncovered a flaw in STP's founding research. In addition, this thesis proposes and demonstrates novel performance enhancing techniques that significantly improve transport protocol throughput.
