Definition

A formatted unit of data transmitted across a packet-switched network that combines a payload with control information (for example: source and destination addresses, length, sequencing and error-check fields) so that intermediate nodes can forward, queue, and, where needed, enable reassembly and delivery independent of a prior circuit.
