Abstract
The Point-to-Point Protocol (PPP) [1] provides a standard method for
transporting multi-protocol datagrams over point-to-point links.
The PPP Compression Control Protocol [2] provides a method to
negotiate and utilize compression protocols over PPP encapsulated
links.
This document describes the use of the Gandalf FZA data compression
algorithm [3] for compressing PPP encapsulated packets.

RFC 1993 Gandalf FZA August 1996
1. Introduction
FZA is a high performance LZ [4] derivative that maximizes
compression at the expense of memory and CPU. Compression
performance can be adjusted based on CPU and memory available.
Multiple PPP packets can be combined in a single compressed frame, or
a single PPP packet can be spread across multiple frames.
1.1. Licensing
Source and object licenses are available on a non-discriminatory
basis for either a royalty or fixed price arrangement. Patent
indemnity is included with the license.
