  • Managing switched virtual circuits in a network
    Patent number: 6549533
    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.
