Executive Summary

Broadband satellites enable Internet access for remote communities and niche markets such as ships and airplanes. However, their inherent characteristics, such as long delays and limited resources, significantly degrade the user quality-of-experience. In this paper, the authors propose a novel HTTP Performance Enhancing Proxy (PEP) that accelerates web-browsing and improves the utilization of satellite resources. They describe TCP and HTTP optimizations, which enable this acceleration. Their performance evaluation shows an average reduction in Web page-load latency of up to 27%.
