   Internet community, and requests discussion and suggestions for
   improvements.  Please refer to the current edition of the "Internet
   Official Protocol Standards" (STD 1) for the standardization state

Abstract

   This document describes an option for negotiating the use of header
   compression on IP datagrams transmitted over the Point-to-Point
   Protocol (RFC 1661).  It defines extensions to the PPP Control
   Protocols for IPv4 and IPv6 (RFC 1332, RFC 2472).  Header compression
   may be applied to IPv4 and IPv6 datagrams in combination with TCP,
   UDP and RTP transport protocols as specified in RFC 2507, RFC 2508
   and RFC 3545.

1.  Introduction

   The IP Header Compression (IPHC) defined in [RFC 2507] may be used for
   compression of both IPv4 and IPv6 datagrams or packets encapsulated
   with multiple IP headers.  IPHC is also capable of compressing both
   TCP and UDP transport protocol headers.  The IP/UDP/RTP header
   compression defined in [RFC 2508] and [RFC 3545] fits within the
   framework defined by IPHC so that it may also be applied to both IPv4
   and IPv6 packets.
