- virtual circuitsearch for term
A type of circuit that provides a connection-oriented service similar to that of circuit switching, but with the following exceptions:
- It is limited to a connection between two end points.
- It has the advantage of economical statistical multiplexing for establishing a logical path through the network.
This logical path can be provided either on a permanent basis by a permanent virtual circuit (PVC), which is equivalent to a leased circuit, or on a request basis by an switched virtual circuit (SVC). Once the logical path is established, the packets are transferred between connected ends, as desired.
