Data Compression over Frame Relay

You can conﬁgure both hardware- and software-based data compression over

WANs running Frame Relay.

Enabling compression improves bandwidth efﬁciency by eliminating redundant

strings in data streams. This, in turn, improves network response times and

reduces line costs.

To use data compression with Frame Relay, the Compression Control parameter

must be set to Enable, the default value (refer to Chapter 3 or Appendix A for

information about how to access this parameter). You must also select WCP

(WAN Compression Protocol) from the protocols menu.

For a complete discussion of data compression, refer to Conﬁguring Data

Compression Services.

Multiline

Frame Relay provides a link redundancy feature called multiline. Multiline lets

you group two or more physical lines that back each other up in case of a failure.

This ensures that information arrives at its destination on the network. In addition,

if both lines are up, the router uses both lines simultaneously. Two or more

physical lines must be available for a multiline conﬁguration.

Figure 2-7

illustrates a multiline conﬁguration.
