Data Compression Overview

Data Transmission

For PPP links using WCP, Network Control Protocol (NCP) negotiations and

WCP negotiations occur simultaneously. When PPP, NCP, and WCP negotiations

are complete, data transmission using compression begins.

For PPP links using Hi/fn LZS, data transmission using compression begins when

CCP and NCP negotiations are complete.

For frame relay and X.25 links, data transmission using compression begins when

WCP negotiations are complete.

Compression Features for Specific Protocols

Bay Networks data compression services vary in some details according to the

WAN protocols that you configure. Read the following sections to learn about

how Bay Networks implements data compression for PPP, frame relay, and X.25

services.

PPP Services

You can use software or hardware data compression on all PPP circuits, including

multiline and multilink, bandwidth-on-demand, dial-on-demand, and dial backup

lines. When you use compression on a bandwidth-on-demand, dial-on-demand, or

dial backup circuit, WCP automatically configures or deletes compression as lines

are added to or removed from the circuit.

PPP Multiline

Multiline

enables you to configure a single circuit consisting of one or more WAN

data paths. A

data path

is a logical point-to-point channel; it can be a permanent

or dial-up physical line, or it can be a virtual circuit connection. Multiline

provides both increased fault tolerance and greater bandwidth between two sites.
