Abstract

This document describes a compression method based on the LZS compression algorithm. This document defines the application of the LZS algorithm to the IP Payload Compression Protocol [IPCOMP]. [IPCOMP] defines a method for applying lossless compression to the payloads of Internet Protocol datagrams.

1. Introduction

1.1 General

This document specifies the application of LZS compression, a lossless compression algorithm, to IP datagram payloads. This document is to be used in conjunction with the IP Payload Compression Protocol [IPCOMP]. This specification assumes a thorough understanding of the IPComp protocol.

1.2 Background of LZS Compression

Starting with a sliding window compression history, similar to [LZ1], Hi/fn developed a new, enhanced compression algorithm identified as LZS. The LZS algorithm is a general purpose lossless compression algorithm for use with a wide variety of data types. Its encoding method is very efficient, providing compression for strings as short as two octets in...
