TCP Extensions for High Performance
RFC 1323, “TCP Extensions for High Performance”, is a Proposed Standard document published in May 1992 by V. Jacobson, R. Braden, D. Borman. It obsoletes RFC 1072, RFC 1185. It has been obsoleted by RFC 7323 — refer to the newer document for the authoritative version. The canonical text is published by the RFC Editor.
Abstract
This memo presents a set of TCP extensions to improve performance over large bandwidth*delay product paths and to provide reliable operation over very high-speed paths. It defines new TCP options for scaled windows and timestamps, which are designed to provide compatible interworking with TCP's that do not implement the extensions. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
