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.

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 [RFC2507] 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 [RFC2508] and [RFC3545] fits within the

   framework defined by IPHC so that it may also be applied to both IPv4

   and IPv6 packets.

RFC 3544             IP Header Compression over PPP            July 2003

   In order to establish compression of IP datagrams sent over a PPP

   link each end of the link must agree on a set of configuration

   parameters for the compression.  The process of negotiating link

   parameters for network layer protocols is handled in PPP by a family

   of network control protocols (NCPs).  Since there are separate NCPs

   for IPv4 and IPv6, this document defines configuration options to be

   used in both NCPs to negotiate parameters for the compression scheme.
