Abstract

   This document contains requirements for the 0-byte IP/UDP/RTP
   (Internet Protocol/User Datagram Protocol/Real-Time Transport
   Protocol) header compression scheme to be developed by the Robust
   Header Compression (ROHC) Working Group.  It also includes the basic
   assumptions for the typical link layers over which 0-byte compression
   may be implemented, and assumptions about its usage in general.

1.  Introduction

   The goal of the Robust Header Compression (ROHC) Working Group 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, using technologies such as WCDMA,
   EDGE, and CDMA-2000.  However, the schemes should also be applicable
   to other future link technologies with high loss and long roundtrip
   times.

   ROHC RTP has become a very efficient, robust and capable compression
   scheme, able to compress the IP/UDP/RTP headers down to a total size
   of only one octet.  This makes ROHC RTP an excellent solution for
   future cellular environments with new air interfaces, such as WCDMA,
   making even speech services possible over IP with an insignificantly
   lower spectrum efficiency compared to existing circuit switched
   solutions.
