V Glossary

VCO

Voltage Controlled Oscillator: An oscillator whose clock frequency is determined by the magnitude of the voltage presented at its input. The frequency changes 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 the 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 relays the cell of the VP.

VLAN

Virtual Local Area Network: Work stations connected to an intelligent device which provides the capabilities to define LAN membership.

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.
