  • System and method for detecting status changes in a network using virtual coordinate mapping
    Patent number: 7979537
    Abstract: A system and method for scalable status change detection in a network of nodes includes embedding node coordinate positions into a virtual map environment. A cluster of nodes are represented with a representative node to form a hierarchy of nodes and clusters where changes in a status of the representative node imply a status change in the nodes of the cluster. By selectively monitoring the representative nodes for the changes in status, the representative nodes create a capability for scalable monitoring of the network.
    Type: Grant

  • Method for generating an annotated network topology
    Patent number: 7782796
    Abstract: A method of generating an annotated network topology of a network is described. The method includes; deriving a network topology by performing a route tracing utility between each pair of endpoints to determine the route taken by packets; initially annotating each network path with an initial value; determining the available bandwidth of a path connecting a pair of endpoints by performing Transfer Control Protocol (TCP) flows between the pair of endpoints; identifying a bottleneck link in the network path, and annotating all edges to generate an annotated network topology wherein available bandwidth annotation of links inside the network is determined using end-to-end network measurements.
