Data Compression Overview

114061 Rev. A 2-5

The only difference between the 32-contexts and 128-contexts Bay Networks

compression daughterboards and net modules is that the 128-contexts

daughterboard and net module have more memory: 2 MB compression/1 MB

decompression, as opposed to 512 KB compression/256 KB decompression for

the 32-contexts daughterboard and net module.

For more information, see the “History Size” section later in this chapter.

How Data Compression Works

The following sections describe how Bay Networks data compression works. As

you read these sections, refer to Figure

2-1, which illustrates CCP and WCP

initialization on a PPP link.

Note: You should plan your network to use hardware compression on the VCs

most important to you within the limits of your equipment. If you conﬁgure

more VCs for hardware compression than your daughterboard or net module

can support, you have no way of controlling which VCs will in fact use

hardware compression. By default, all VCs that exceed the hardware context

limit use software compression.
