Transmission Control Protocol (TCP) is widely used for the transport layer protocol in most Internet and Intranet applications. The link characteristics of a specific link environment such as satellite has been limited and degraded by its link characteristics. To address such limitations Performance Enhancing Proxies (PEPs) have been designed and introduced to improve the operation of internet and intranet protocols in certain environments where a link or subnet suffers performance degradation with high error rates and with low bandwidths. This paper discuss the overview of PEPs together with the problems and drawbacks of such technologies to improve the degraded performance of TCPs.
