packet
A group of bits that is used in packet switching and that is transmitted as a discrete unit. A packet includes a message
element and a control information element (IE). The message element is the data. The control information element is the
header. In each packet, the message element and the control IE are arranged in a specified format. See also
element (IE) packet switching
;
packet assembly/disassembly (PAD)
The process of packetizing control data and user data from a transmitting device before the data is forwarded through the
packet network.The receiving device disassembles the packets, removes the control data, and then reassembles the
packets, thus reconstituting the user data in its original form.
packet bus
A wide-bandwidth bus that transmits packets.
packet switching
A data-transmission technique that segments and routes user information in discrete data envelopes that are called
packets. Control information for routing, sequencing, and error checking is appended to each packet. With packet
switching, a channel is occupied only during the transmission of a packet. On completion of the transmission, the channel
is made available for the transfer of other packets. See also
