What is Data Compression?
To establish communications over a PPP link, each end of the connection must first send packets to configure and test the data link. After the link has been established, optional facilities may be negotiated as needed. One such facility is data compression. A wide variety of compression methods may be negotiated, although typically only one method is used for both directions of the link.
Data compression is a process where the effective throughput is increased by encoding data in such a way that fewer bits are required to represent it. For example, a text file might be compressed by representing common words with single characters; thus if the word “the” is represented by the character “@”, it will be transmitted three times faster. Popular compression algorithms typically reduce the size of the data by 50%, effectively doubling the rate at which it is transmitted.
The Compression Control Protocol (CCP) works with MLPPP and is responsible for configuring, enabling, and disabling data compression algorithms on both ends of the
