   Switched Virtual Circuit - SVC

A switched virtual circuit is an automatically and temporarily created virtual connection that is used for a communication session.

This diagram shows how a switched virtual circuit (SVC) uses an address provided by the user to establish a logical (virtual) path through a communications network. In this example, a SVC is created by using the destination address to determine the required programming of routing tables in switches within the data network. These routing tables assign data transfer connections between input and output channel on each switch. For example, as data from the sending computer (portable computer) is sent into input channel 3 of the first switch, it is transferred to the output channel 4. This process will repeat for any data that is sent from the sending computer to the destination computer during the switched connection.
