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.

� � 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.
