Packet Compression
Packet compression can increase throughput and shorten the times needed for data transmission.
You can enable packet compression for Frame Relay VCs and for PPP ports, however, both ends of
a link must be configured to use packet compression.
Enabling compression on WAN serial links should be decided on a case by case basis. Important
factors to consider include:
• average packet size
• nature of the data
• link integrity
