  • Patent number: 7197040
    Abstract: A system for, and method of, configuring border gateway selection for transit traffic flows in a computer network. In one embodiment, the system includes: (1) a border gateway modeler that builds a model of cooperating border gateways, the model including capacities of the border gateways and (2) a traffic flow optimizer, associated with the border gateway modeler, that initially assigns traffic to the border gateways in accordance with a generalized assignment problem and subsequently reassigns the traffic to the border gateways based on cost until the capacities are respected.
    Type: Grant
    Filed: July 1, 2002
    Date of Patent: March 27, 2007
    Assignee: Lucent Technologies Inc.
    Inventors: Thomas C. Bressoud, Rajeev Rastogi, Mark A. Smith

  • Publication number: 20010056492
    Abstract: The present invention provides a system, method and apparatus for maintaining a connection between a server and a client by receiving a message, determining whether to store one or more elements of the message, storing the one or more elements of the message when the one or more elements of the message are to be stored, transmitting the message, and determining whether the server has failed and when the server has failed, restoring the server to a pre-failure connection state using the one or more stored message elements.

  • Patent number: 5968185
    Abstract: In a fault-tolerant computer system, a primary replica supervisor is interposed between an operating system and a primary replica of an application program being executed by a primary processor. An object-code editor locates calls to the operating system and loops in the application program and inserts instruction sequences that enable the replica supervisor to intercept the calls to the operating system, results returned by the operating system as a result of the calls and asynchronous events delivered by the operating system to the replica. A backup replica supervisor is similarly interposed between an operating system and a backup replica of the application program being executed by a backup processor. The primary replica interacts with an environment.
