Summary of Bay Networks Data Compression Features

You can configure both software- and hardware-based compression on a circuit or

line basis. Features specific to software and hardware compression follow.

Software-Based Data Compression

There are two Bay Networks software compression protocols:

• WAN Compression Protocol (WCP) -- for Point-to-Point Protocol (PPP),

frame relay, and X.25 links

• Stac LZS -- for PPP links only

These two protocols use different Lev-Zimpel algorithms to implement

compression and they provide different levels of interoperability between Bay

Networks routers and routers made by other vendors.

If both ends of the connection are Bay Networks routers, use WCP as the

compression protocol. If the connection is a PPP link and only one end of the

connection is a Bay Networks router, use Stac LZS.

Software-based data compression works over WAN links. Specifically, WCP

works with PPP, frame relay, and X.25 links, while Stac LZS works only with PPP

links. Both WCP and Stac LZS work with PPP multilink. WCP also works with

PPP multiline.

Software compression includes the following features:

• Compression for a Bay Networks Fast Routing Engine (FRE

) module at

4 x 128 KB/s compressed throughput, full duplex; or 512 KB/s aggregate

compressed throughput

• Compression on a Bay Networks Access Node (AN

) platform at

2 x 64 KB/s compressed throughput, full duplex; or 128 KB/s aggregate

compressed throughput

Note:

The Hi/fn

™

Stac LZS

Compression Option is not included with your

initial purchase of Bay Routing Software (BayRS). Bay Networks Stac LZS

compression software incorporates LZS

licensed from Hi/fn

™

and therefore

must be separately purchased.
