RObust Header Compression : A Profile for TCP/IP

Overview

RFC 6846, “RObust Header Compression : A Profile for TCP/IP”, is a Proposed Standard document published in January 2013 by G. Pelletier, K. Sandlund, L-E. Jonsson, M. West. It obsoletes RFC 4996. The canonical text is published by the RFC Editor.

Abstract

This document specifies a RObust Header Compression (ROHC) profile for compression of TCP/IP packets. The profile, called ROHC-TCP, provides efficient and robust compression of TCP headers, including frequently used TCP options such as selective acknowledgments (SACKs) and Timestamps.

ROHC-TCP works well when used over links with significant error rates and long round-trip times. For many bandwidth-limited links where header compression is essential, such characteristics are common.

This specification obsoletes RFC 4996. It fixes a technical issue with the SACK compression and clarifies other compression methods used. [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.
