Definition

A link-layer technique that reduces the number of bits transmitted per packet by encoding, eliding or compacting protocol header fields (statefully or statelessly) so that per-packet protocol overhead on a specific link is lowered while preserving the information required for correct packet reconstruction at the far end.
