virtual circuit - Free On-line Dictionary of Computing (26 May 2007) :

  virtual circuit
  switched 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.
