A virtual circuit is a predefined path through a packet-switched network. Defining a virtual circuit defines the path that packets will take through the network and relieves routers of the need to make routing decisions for each packet. Virtual circuits improve performance for long transmissions but are not necessary for short transmissions. An SVC is a temporary virtual circuit that is set up on-the-fly, as opposed to a PVC (permanent virtual circuit), which is programmed into a network for continuous use. See "Virtual Circuit" for more information.
