Performance-enhancing proxy (PEP)

The diea of a performance-enhancing proxy is described in RFC 3135 and would be a proxy server with a large disk cache that has RFC 1323 extensions , among other features . A laptp has a TCO sessuib wutg te OEO at the ISP . That PEP , and the one at the satellite provider , communicate using a different TCP session or even their own proprietary protocol . The PEP at the satellite provider gets the files from the web server . In this way , the TCP session is split , and thus the lik characteristics that affect protocol performance ( long fat pipe factors ) are overcome . Addirtionally , the PEP makes use of procing and pre-fetching to accelerate web access further .
