UDP
User Datagram Protocol. A simple, datagram-oriented transport-layer protocol. A TCP/IP
protocol describing how messages reach applications programs within a destination computer.
This protocol is normally bundled with IP layer software. UDP is a transport layer,

- V -
VC
Virtual circuit. Network facilities that give the appearance to the user of an actual end-to-end
circuit. A communications link set up on a per-call basis of either voice or data that appears to
the user to be a dedicated point to point circuit.
VCC
Virtual circuit connection. Same as permanent virtual connection (PVC).
VCI
Virtual circuit identifier. A unique numerical tag, defined by a 16 bit field in the ATM cell
header, that identifies a VC over which a stream of cells is to travel during the course of a
particular session between devices.
VC-
MUX
Virtual circuit multiplexing. Encapsulation method that performs multiplexing of higher-layer
protocols using ATM virtual circuits.
VJ
Van Jacobson. Abbreviation for a compression standard documented in RFC 1144.
VP
Virtual path.
