Us Patents

  • System And Method For Multipoint-To-Multipoint Multicasting

    view source
  • US Patent:
    6353596, Mar 5, 2002
  • Filed:
    Apr 12, 1996
  • Appl. No.:
    08/631869
  • Inventors:
    Matthias Grossglauser - Balsthal, CH
    Kadangode K. Ramakrishnan - Berkeley Heights NJ
  • Assignee:
    Lucent Technologies Inc. - Murray Hill NJ
  • International Classification:
    H04L 1256
  • US Classification:
    370256, 370390, 370409
  • Abstract:
    A system and method are provided for a scalable and efficient multipoint-to-multipoint multicast in packet and sub-packet based communications networks. The methodology of the invention incorporates an additional switching feature called cut-through forwarding, which enables the mapping of several incoming virtual channels into one or several outgoing virtual channels. The inventive methodology further provides a shared tree spanning all senders and receivers of the multicast group. Centrally initiated group setup as well as dynamic group membership changes are incorporated into the invention. An additional feature of the invention, designated “short-cutting”, allows for the transmission of a packet to follow the shortest path along the shared tree. A methodology is also provided for achieving interoperability among switching nodes in a network which are capable of fully implementing the multipoint-to-multipoint multicast method of the invention and other switching nodes which lack that capability.
  • Method And Apparatus For Managing Congestion Within An Internetwork Using Window Adaptation

  • US Patent:
    6438101, Aug 20, 2002
  • Filed:
    May 27, 1998
  • Appl. No.:
    09/085954
  • Inventors:
    Lampros Kalampoukas - Eatontown NJ
    Kadangode K. Ramakrishnan - Berkeley Heights NJ
    Anujan Varma - Santa Cruz CA
  • Assignee:
    ATT Corp. - New York NY
    The Regents of the University of California - Oakland CA
  • International Classification:
    G01R 3108
  • US Classification:
    370229, 370235, 37039543, 370401
  • Abstract:
    Congestion is controlled in an internetwork having at least two segments coupled by a router where at least one connection between communication devices passes through the router. Each connection is assumed to use a window-based flow control protocol between its source and destination. On receiving an acknowledgment from a connection in the router, where the acknowledgment contains a window size set by the destination, the router adaptively determines a second window size for the connection based on the routers average buffer occupancy and its instantaneous buffer occupancy. If the window size in the acknowledgment exceeds this second window size, the window size in the acknowledgment is overwritten to select the second window size. The router then forwards the acknowledgment to the source, thereby controlling the window size available to the source as a function of the congestion in the router.

  • International Classification:
    H04M 700
  • US Classification:
    379219, 37920201, 37922001
  • Abstract:
    Network resources for a call between a calling party and a called party are allocated. The network resources for the call are reserved based on a reservation request. The network resources are reserved before any one network resource from the reserved network resources is committed. The reserved network resources for the call are committed when a called party indicates acceptance for the call.

  • Filed:
    Dec 22, 1999
  • Appl. No.:
    09/468902
  • Inventors:
    William Todd Marshall - Chatham NJ
    Partho Pratim Mishra - Millbrae CA

  • Assignee:
    ATT Corp. - New York NY
  • International Classification:
    H04M 300
  • US Classification:
    379386, 379418, 379372, 379 8812, 379 2702
  • Abstract:
    A ring back signal for a call between a calling party and a called party can be simulated. A ring back message associated with the call is received. The calling party is associated with a first network. The called party is associated with a second network. A prestored ring back signal is selected from a set of prestored ring back signals based on the ring back message and/or a called number for the call. The selected prestored ring back signal is associated with the second network and is different from a second prestored ring back signal associated with the first network. The prestored ring back signal is sent to the calling party.

    H04M 1500
  • US Classification:
    37911422, 37911401, 37911421, 37911423
  • Abstract:
    A call is forwarded by connecting the call between an originating location and a forwarding location without connecting the call through a terminating location. The originating location is associated with a calling party. The terminating location is associated with a dialed number. The terminating location and the forwarding location is associated with the called party. A bill for the call is apportioned between the calling party and the called party. The bill portion for the calling party is a function of the originating location and the terminating location. The bill portion for the called party is a function of the terminating location and the forwarding location.
  • Traffic Control System Having Distributed Rate Calculation And Link Flow Control

  • US Patent:
    6615271, Sep 2, 2003
  • Filed:
    Oct 19, 1999
  • Appl. No.:
    09/421021
  • Inventors:
    Anthony G. Lauck - Wellesley MA
    Anna Charny - Sudbury MA
    Kadangode K. Ramakrishnan - Maynard MA
  • Assignee:
    Enterasys Networks, Inc. - Andover MA
  • International Classification:
    G06F 1516
  • US Classification:
    709232
  • Abstract:
    A rate based, end to end flow control system is disclosed for a communications network. The disclosed rate based flow control system includes each source end station selecting its transmission rate from a set of permitted discrete transmission rates. The set of permitted discrete transmission rates is based on a logarithmic encoding. The disclosed rate based traffic control system further requires each source end station to send one end to end control cell every time period T. The time period T is also known by switches in the communications network and is used to periodically calculate an available allocation (“fair share”) of bandwidth at a switch for a given virtual circuit.
