Compression  

Definition:

There are many types of compression (see CODEC). This tutorial explains IP compression. Payload Compression reduces the size of the data (content). There are many compression techniques which reduce file sizes by eliminating spaces, redundant characters and phrases and repetitive sequences. Payload Compression leaves the IP Header unchanged allowing the packet to be switched (routed) by X.25, Frame Relay, SMDS-Switched Multi-megabit Data Services, and ATM-Asynchronous Transfer Mode. Link Compression reduces the size of the IP Header and the data. Link Compression is encapsulated with PPP-Point-to-Point Protocol and LAPB-Link Access Protocol Balanced. Header Compression reduces the size of the IP Header. Header Compression does not reduce the data size only the header information and is used with HDLC-High-level Data Link Control and X.25.
