Connecting Compression Network Modules
This chapter describes the compression network module for Cisco 3600 series routers and contains the following sections:
•
Compression Network Module LEDs
This module provides hardware assistance to protocols that use compression and decompression, reduces the load on the CPU caused by software compression, and improves router performance.
Tip
Compression Network Modules
The compression network module (NM-COMPR) does not provide network interfaces of its own, but instead compresses and decompresses data passing through interfaces on other network modules or WAN interface cards in the router. (See Figure 14-1.)
Hardware compression is supported only over Point-to-Point Protocol (PPP) links. The compression network module supports only the Stacker compression algorithm.
Cisco IOS Release 11.3 and later releases allow Frame Relay compression support using the FRF.9 compression algorithm.
