Cisco internetworking devices use the Stacker and Predictor data compression algorithms. The Compression Service Adapter (CSA) only supports the Stacker algorithm. The Stacker method is the most versatile, because it runs on any supported point-to-point layer-2 encapsulation. Predictor only supports PPP and LAPB.

Cisco IOS Data Compression These compress data on a per-connection basis or at the network trunk level. Compression can take place on an entire-packet, header-only, or payload-only basis. The success of these solutions are easy to measure via compression ratio and platform latency.

What is a compression ratio?

The efficiency and effectiveness of a compression scheme is measured by its compression ratio, the ratio of the size of uncompressed data to compressed data.
A compression ratio of 2:1 (which is relatively common) means that the compressed data is half the size of the original data.

What is data compression?

Data compression provides a coding scheme at each end of a transmission link that allows characters to be removed from the frames of data at the sending side of the link and then replaced correctly at the receiving side.
Because the condensed frames take up less bandwidth,we can transmit greater volumes at a time.
