Description of Working Group:
The Robust Header Compression (ROHC) Working Group was formed to develop
new header compression protocols, designed to suit today's and future
target link technologies. Most specifically, the ROHC protocols were to
take into account typical needs presented by various wireless link
technologies, and perform well for cellular links built using
technologies such as WCDMA, EDGE, and CDMA-2000. Protocol development
has thus focused on coping with issues such as high loss rates and long
round trip times.
The WG has specified a common compression protocol platform, the ROHC
framework, along with a number of compression protocols (profiles). Most
focus has been on compression of the Real-time Transport Protocol (RTP)
headers, but profiles have also been specified for compression of UDP,
ESP, IP-only, UDP-Lite, and TCP headers. The WG has further produced a
ROHC link integration specification for PPP, an optimized RTP
compression scheme for "0-byte compression", a ROHC MIB, as well as
various informational documents related to ROHC header compression
and/or header compression in general.
In addition to the work on header compression, the ROHC WG has also
developed the SigComp (Signaling Compression) protocol for end-to-end
compression of text-based signaling protocol messages.
The working group maintains connections with other standardization
organizations developing cellular technology for IP, such as 3GPP and
3GPP-2, to ensure that its output fulfills their requirements and will
be put to good use.
The current aims of the working group are:
- to carry out a re-work of the ROHC framework and profiles
specifications, hereafter referred to as the ROHCv2 project. The purpose
of the ROHCv2 project is to generate a separate framework specification
as well as a set of revised compression profiles. One specific goal with
the ROHCv2 profiles is to improve tolerance to packet reordering between
compressor and decompressor.
- to update and correct the original profile specifications through
publication of the "Corrections and Clarifications to RFC 3095"-
document.
- to finalize the ROHC profile work for TCP header compression.
- to develop and/or document proper protocol solutions to apply ROHC
over IPsec tunnels.
- to finalize the "SigComp implementer's guide" and "SigComp for SIP"
documents.
The longer term goal of the working group is to advance all its
specifications to Draft Standard status (with an exception for the
original profiles being revised as part of the ROHCv2 activity).
