Frame Relay Overview
308624-14.10 Rev 01
1-21
To use data compression with frame relay, ensure that compression control is
enabled (the default) and select WCP as one of the protocols for the interface. For
more information about enabling compression, see “Disabling and Reenabling
Data Compression for PVCs” on page 4-26. For more information about data
compression, see Configuring Data Compression Services.
Data Encryption
Nortel 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
protocol prioritization, also called priority queueing. 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.
When you select frame relay on a circuit, the router enables protocol prioritization
automatically. It does so because the DLCMI packets must have a higher priority
than any other packets you are sending across the network.
Enabling frame relay multiline affects protocol prioritization. For more
information, see “Protocol Prioritization and Multiline Incompatibility
” on
page 1-37
.
For information about configuring protocol prioritization, see Configuring Traffic
Filters and Protocol Prioritization.
