Jose Carlos Pinheiro has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Methods and devices for providing fast and robust overload control
    Patent number: 7729252
    Abstract: Techniques are provided for controlling overload conditions using two values; an acceptance rate fraction allowed value and an occupancy fraction allowed value. The inventive techniques allow quick response to the sudden onset of overload conditions, are robust enough to be used when processor speeds are increased and compare favorably to known techniques.
    Type: Grant
    Filed: May 30, 2003
    Date of Patent: June 1, 2010
    Assignee: Alcatel-Lucent USA Inc.
    Inventors: Adiseshu Hari, Mehmet Karaul, Sneha Kasera, Thoma F. La Porta, Catherine R. Loader, Jose Carlos Pinheiro, Robert A. Latimer
  • METHODS AND DEVICES FOR PROVIDING EARLY DETECTION, CONTROLLED ELIMINATION OF OVERLOAD CONDITIONS AND THE RETURN OF A CONTROLLED LEVEL OF TRAFFIC AFTER SUCH CONDITIONS HAVE BEEN SUBSTANTIALLY ELIMINATED
    Patent number: 6907115
    Abstract: Overload conditions affecting a processor of a network switch or the like are substantially eliminated, and the processing of traffic is gradually allowed to increase, by inserting, and then monitoring one or more probes which are placed into a queue of the processor. During a given measurement interval, if the number of probes exceeds a threshold then an overload condition exists. This condition is subsequently reduced using “multiplicative decrease” techniques. Conversely, if the threshold is not exceeded and there is little or no chance an overload condition can quickly reappear, traffic is allowed to once again be processed gradually using “additive increase” techniques.
