RObust Header Compression : A Link-Layer Assisted Profile for IP/UDP/RTP
RFC 3242, “RObust Header Compression : A Link-Layer Assisted Profile for IP/UDP/RTP”, is a Proposed Standard document published in April 2002 by L-E. Jonsson, G. Pelletier. It has been obsoleted by RFC 4362 — refer to the newer document for the authoritative version. The canonical text is published by the RFC Editor.
Abstract
This document defines a ROHC (Robust Header Compression) profile for compression of IP/UDP/RTP (Internet Protocol/User Datagram Protocol/Real-Time Transport Protocol) packets, utilizing functionality provided by the lower layers to increase compression efficiency by completely eliminating the header for most packets during optimal operation. The profile is built as an extension to the ROHC RTP profile. It defines additional mechanisms needed in ROHC, states requirements on the assisting layer to guarantee transparency, and specifies general logic for compression and decompression making use of this header-free packet. [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.
