Differentiate switched virtual circuit and Permanent virtual circuit.

Differentiate switched virtual circuit and Permanent virtual circuit.
by

1 Answer

Answer :

Switched virtual circuit format is comparable conceptually to dial-up line in circuit switching. In  this method, a virtual circuit is created whenever it is needed and exits only for the duration of specific  exchange.  
Permanent virtual circuits are comparable to leased lines in circuit switching. In this method, the  same virtual circuit is provided between two uses on a continuous basis. The circuit is dedicated to the  specific uses.
