1. Introduction

In order to establish communications over a PPP link, each end of the

link must first send LCP packets to configure and test the data link

during Link Establishment phase. After the link has been

established, optional facilities may be negotiated as needed.

One such facility is data compression. A wide variety of compression

methods may be negotiated, although typically only one method is used

in each direction of the link.

A different compression algorithm may be negotiated in each

direction, for speed, cost, memory or other considerations, or only

one direction may be compressed.

2. Compression Control Protocol (CCP)

The Compression Control Protocol (CCP) is responsible for

configuring, enabling, and disabling data compression algorithms on
