Abstract
This paper will discuss current deployment scenarios for Performance Enhancement Proxies (PEP) technologies in broadband satellite access systems from the perspective of one PEP technology provider. Recent improvements such as DVB-S2 can provide substantial gains at the link layer. In order to achieve further efficiency gains, the satellite industry is now forced to look elsewhere – namely other layers in the data communications network stack. Satellite terminal manufacturers are now moving beyond basic TCP acceleration techniques to more comprehensive optimization techniques that incorporate advances in data compression and flexibility for more deployment scenarios. Some of the advances for PEP technology are in part due to CPU and memory technology advances, resulting in increasingly affordable access to computing power, allowing PEP manufacturers deliver substantial performance and bandwidth savings gains.
