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.
