MEANS OF TRANSPORTING DATA OVER A PACKET-SWITCHED NETWORK SO AS TO EMULATE A DEDICATED PHYSICAL LINK BETWEEN NODES

Permanent virtual circuit; Virtual call capability; Virtual circuit capability; Virtual call facility; Switched virtual circuit; Private virtual circuit; Virtual circuits; Virtual circuit switching; Virtual connection; WAN Virtual Circuits; Switched virtual circuits; Permanent virtual circuits; Virtual Circuit; Virtual channel (computer networking)

A virtual circuit (VC) is a means of transporting data over a packet-switched network in such a way that it appears as though there is a dedicated physical link between the source and destination end systems of this data. The term virtual circuit is synonymous with virtual connection.

virtual circuit

MEANS OF TRANSPORTING DATA OVER A PACKET-SWITCHED NETWORK SO AS TO EMULATE A DEDICATED PHYSICAL LINK BETWEEN NODES

<networking> A connection-oriented network service which is implemented on top of a network which may be either connection-oriented or connectionless (packet switching). The term "switched virtual circuit" was coined needlessly to distinguish an ordinary virtual circuit from a {permanent virtual circuit}. (One of the perpetrators of this confusion appears to be ["Networking Essentials", 1996, Microsoft Press, ISBN 1-55615-806-8], a book aimed at people preparing for the MCSE exam on LANs and WANs). Not to be confused with switched virtual connection. (2001-10-26)

Permanent Virtual Circuit

MEANS OF TRANSPORTING DATA OVER A PACKET-SWITCHED NETWORK SO AS TO EMULATE A DEDICATED PHYSICAL LINK BETWEEN NODES

<networking> (PVC, or in ATM terminology, "Permanent Virtual Connection") A virtual circuit that is permanently established, saving the time associated with circuit establishment and tear-down. (1997-10-06)
