SatERN: A PEP-Less Solution for Satellite Communications
In networks with very large delay like satellite IP-based networks, standard TCP is unable to correctly grab the available resources. To overcome this problem, Performance Enhancing Proxies (PEPs), which break the end-to-end connection and simulate a receiver close enough to the sender, can be placed before the links with large delay. Although splitting PEPs does not modify the transport protocol at the end nodes, they prevent the use of security protocols such as IPsec. In this paper, the authors propose solutions to replace the use of PEPs named SatERN.
