Data Compression

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. Enabling compression on a frame relay link also provides

reliability. Both sides of a link using compression maintain a history of data that

has already traveled across the network, and WCP (WAN Compression Protocol)

detects and retransmits dropped packets.

To use data compression with frame relay, the Compression Control attribute or

parameter must be set to Enable, the default value (see “Enabling Compression for

PVCs” on page 3-32 for information about how to access this attribute or

parameter). You must also select WCP from the protocols menu.

For a complete discussion of data compression, see Configuring Data

Compression Services.

Data Encryption

Bay Networks data encryption services enable you to protect sensitive traffic on

your network. Encryption for frame relay circuits works with direct mode PVCs

only. For information about and instructions for configuring data encryption, see

Configuring Data Encryption Services.

Protocol Prioritization

You can set priorities for the traffic sent across a synchronous line interface using

a process called protocol prioritization. The ability to prioritize traffic is important

for an application that is time-sensitive and that requires a fast response.

For example, a user at router A participating in a Telnet session with router B

requires a more immediate response than does a user at router A performing a file

transfer with router B.
