Applications

Network Address Translation

Using private addresses on a network and NAT/NAPT for interactions over an internetwork connection hides the internal address from the rest of the world. Access is restricted to only those services that are specifically designated to be available. Please see section 2.4.2 for more information on Network Address Translation.

Filters

The programmable filtering functions available on the router provides a very powerful means of controlling traffic flow to and from a network.

Compression

Compressing data allows data throughput rate considerably greater than the physical line rate. The actual rate achieved will depend on how compressible the specific data is. Generally, graphics and databases compress up to 600%, text 400 to 500%, binary codes about 200%.

At line rates above 256 Kbps, compression is not effective as it takes more time to perform the compression than to transmit the raw data.
