This document is a survey of Performance Enhancing Proxies (PEPs)
often employed to improve degraded TCP performance caused by
characteristics of specific link environments, for example, in
satellite, wireless WAN, and wireless LAN environments.  Different
types of Performance Enhancing Proxies are described as well as the
mechanisms used to improve performance.  Emphasis is put on proxies
operating with TCP.  In addition, motivations for their development
and use are described along with some of the consequences of using
them, especially in the context of the Internet.

This document is a product of the Performance Implications of Link
Characteristics Working Group of the IETF.
