SVC (Switched Virtual Circuit) Related Entries Web Links New/Updated Information Note: Many topics at this site are reduced versions of the text in "The Encyclopedia of Networking and Telecommunications." Search results will not be as extensive as a search of the book's CD-ROM. 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. Copyright (c) 2001 Tom Sheldon and Big Sur Multimedia.
