RFC 1072: TCP extensions for long-delay paths

This RFC has been replaced. Do not implement against it for new work — it was formally obsoleted by RFC 1323, RFC 2018, RFC 6247.

Current document in this lineage: RFC 2018 — TCP Selective Acknowledgment Options; RFC 6247 — Moving the Undeployed TCP Extensions RFC 1072, RFC 1106, RFC 1110, RFC 1145, RFC 1146, RFC 1379, RFC 1644, and RFC 1693 to Historic Status; RFC 7323 — TCP Extensions for High Performance

In plain English — editorial summary, not part of the RFC

This RFC proposes a set of extensions to the TCP protocol to provide efficient operation over a path with a high bandwidth*delay product. These extensions are not proposed as an Internet standard at this time. Instead, they are intended as a basis for further experimentation and research on transport protocol performance.
