virtual circuit
<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.
