A Design Methodology of Advanced-PEPs Architecture for TCP Satellite Connection and Bandwidth Management

In the network environment of the Internet and Intranet, Transmission Control Protocol (TCP) is Representative application of transport layer protocols. TCP based network specific environment and other upper-layer protocol performance should be limited according to link feature. To solve these problems for typical techniques is Enhanced-TCP based which use PEP. PEPs is placed between the degraded network segment complementary problems, and efficiently manage developed for efficient network environment. Because of these characteristics, PEPs in the satellite communications environment good solution has been Level rised. PEPs system is typical for a satellite-based network. However, because of the feature satellite network, has the disadvantage of high packet loss ratio and Long Return Trip Time (RTT). In addition, many problems remain, and various solutions are discussed. in this paper to solve these problems, an 'Advanced-PEP Architecture' based methodology of the new technique is proposed.
