Abstract

This document contains requirements on the TCP/IP header compression scheme (profile) to be developed by the RObust Header Compression (ROHC) Working Group. The document discusses the scope of TCP compression, performance considerations, assumptions about the surrounding environment, as well as Intellectual Property Rights concerns. The structure of this document is inherited from RFC 3096, which defines IP/UDP/RTP requirements for ROHC.

RFC 4163              Requirements on ROHC TCP/IP            August 2005


1.  Introduction

   The goal of the ROHC WG is to develop header compression schemes that
   perform well over links with high error rates and long link roundtrip
   times.  The schemes must perform well for cellular links that use
   technologies such as Wideband Code Division Multiple Access (W-CDMA),
   Enhanced Data rates for GSM Evolution (EDGE), and CDMA2000.  However,
   the schemes should also be applicable to other link technologies with
   high loss and long roundtrip times.

   The main objective for ROHC has been robust compression of IP/UDP/RTP
   [5], but the WG is also chartered to develop new header compression
   solutions for IP/TCP [1], [2].  Because TCP t...
