  • Publication number: 20100217773
    Abstract: In accordance with the teachings of the present invention, a method of data drilling is presented. A network database is deployed in a network, such as the Internet, for broad-based user access. Network information is stored in the network database and is organized in layers. A graphical user interface with data objects is presented to an end user. Selecting a data object generates a query performed by a server. Each query produces more details on an initially selected data object.
    Type: Application

  • Publication number: 20080239991
    Abstract: A method and apparatus for provide highly efficient traffic routing for a wide range of possible traffic matrices (TM) in an intra-domain network. That routing optimally balances the traffic loads over a range of traffic matrices so as to minimize the deviation for any particular traffic matrix from the optimal routing. Such a routing provides a guaranteed performance ratio against the best possible network routing. The invention utilizes a method of optimally configuring a traffic network based on solving a linear program to obtain the optimal routing, and then configuring the routing on the network accordingly.
