Abstract
A system and method for managing switched virtual circuits in a virtual circuit switched network. A preferred embodiment method for managing switched virtual circuits comprises determining that a switched virtual circuit has been established in a virtual circuit switched network by a network access device, monitoring the switched virtual circuit while the switched virtual circuit is active, and storing bandwidth and duration information for the switched virtual circuit upon termination of the switched virtual circuit. Another preferred embodiment method comprises receiving a request for establishing the switched virtual circuit from a network access device, generating connection parameters for establishing the switched virtual circuit in the virtual circuit switched network, and sending a reply including the connection parameters to the network access device. A preferred embodiment network management system comprises a network access device gateway having an interface to a network access device in the virtual circuit switched network, a network administrator database connected to the gateway, the database including rules and objects representing characteristics of the virtual circu…
