VCO
Voltage Controlled Oscillator: An oscillator whose clock frequency is determined
by the magnitude of the voltage presented at its input. The frequency change s when
the voltage changes.
VD
Virtual Destination. Refer to VS/VD.
VF
Variance Factor: VF is a relative measure of cell rate margin normalized by th e
variance of the aggregate cell rate on the link
Virtual Channel Switch
A network element that connects VCLs. It terminates VPCs and translates VCI
values. It is directed by Control Plane functions and relays the cells of a VC.
Virtual Path Switch
A network element that connects VPLs. It translates VPI (not VCI) values and is
directed by Control Plane functions. It re lays the cell of the VP.
VLAN
Virtual Local Area Network: Work stations connected to an intelligent device
which provides the capabilities to define LAN memb e rship.
VMEBUS
VEASA Module European Bus: A 32-bit bus developed by Motorola, Signetics,
Mostek, and Thompson CSF. Used widely in industrial, commercial, and military
applications with over 300 manufacturers of VMEbus products worldwide.1
VP
Virtual Path: A unidirectional logical association or bundle of VCs.
VPC
Virtual Path Connection: A concatenation of VPLs between Virtual Path
Terminators (VPTs). VPCs are unidirectional.
