There are many types of Performance Enhancing Proxies (PEPs). Different types of PEPs are used in different environments to overcome different link characteristics which affect protocol performance [1]. The main examples concerns satellite and wireless networks, which represent the most challenging environments. In the following, the main concepts representing the state of the art of the PEP wi...
