Abstract
This document describes a protocol intended to provide lossless
compression for Internet Protocol datagrams in an Internet
environment.
1. Introduction
IP payload compression is a protocol to reduce the size of IP
datagrams. This protocol will increase the overall communication
performance between a pair of communicating hosts/gateways ("nodes")
by compressing the datagrams, provided the nodes have sufficient
computation power, through either CPU capacity or a compression
coprocessor, and the communication is over slow or congested links.
IP payload compression is especially useful when encryption is
applied to IP datagrams. Encrypting the IP datagram causes the data
to be random in nature, rendering compression at lower protocol
layers (e.g., PPP Compression Control Protocol [RFC-1962])
ineffective. If both compression and encryption are required,
compression MUST be applied before encryption.
