virtual circuit (VC), frame relay networking

In frame relay networking, the equivalent of a physical connection to a

destination address using shared facilities. Virtual circuits can be permanent

(PVC) or switched (SVC). The virtual circuit is anchored in the function

processors that are connected to the end user devices.

Virtual Circuit System (VCS)

The software system that allows Nortel Multiservice Switch networks to offer

virtual circuits.

virtual interface

In ATM networking, an interface that is configured under a virtual path

terminator, permitting multiple virtual interfaces under a single port. This

configuration contrasts with actual or real interfaces that have a one-to-one

correspondence with a physical port. Virtual interfaces, like their actual

interface counterparts, can be any of UNI, IISP, AINI, or PNNI interfaces. Also

known as virtual UNI or VUNI, virtual IISP or VIISP, virtual AINI or VAINI, and

virtual PNNI or VPNNI.

virtual IP router (VIPR)

Virtual IP router (VIPR) is an IP service that provides basic IP routing in a flat

IP network.This service is also referred to as Basic IP.

virtual LAN (VLAN)

IEEE 802.1Q Ethernet virtual LAN (VLAN) is a subset of the active topology

of a Bridged LAN. A VID is associated with each VLAN.

virtual link (VL)

An IMA virtual link refers to the combination of multiple physical links that use

the inverse multiplexing process to transmit traffic across these links. A virtual

link is presented as a single link to the ATM layer. A VL originates on one FP

running the IMA feature and terminates on another FP running the IMA

feature. Typically, these two FPs are on two different Nortel Multiservice

Switch nodes. Any virtual link can consist of a maximum of eight DS1/E1

physical links on an FP running IMA.

Virtual Media (VM)

Virtual Media (VM) is a Nortel Networks proprietary, hardware independent

broadcast medium. VM is not associated with a physical port but rather a

logical interface.

virtual path (VP)

In frame relay, the equivalent of a physical connection to a destination address

using shared facilities. Virtual paths can be permanent (PVP) or switched

(SVP). The virtual path is anchored in the function processors that are

connected to the end user devices.
