  • System, method, and computer-readable medium for determining a layer 2 path trace in a heterogeneous network system
    Patent number: 7742426
    Abstract: A system, method, and computer-readable medium for performing network system diagnostics is provided. The method includes obtaining a respective identification of a first target device and a second target device deployed in a network; iteratively querying neighbor devices of at least one node in a communications path between the first and second target devices, wherein the neighbor devices and the first and second target device may comprise heterogeneous network nodes; and generating a layer 2 path trace that comprises identification of network devices interconnected on a physical path between the first and second target devices. A computer-readable medium includes instructions for execution by a processing system, wherein the instructions are configured to perform the foregoing method. A system includes a data processing system including a processor device for executing a diagnostics engine implemented as a set of computer-executable instructions configured to perform the foregoing method.

  • Methods, systems and computer program products for evaluating network performance using diagnostic rules identifying performance data to be collected
    Patent number: 7680920
    Abstract: A path of a communication connection between a first node and a second node is determined. The path includes at least one connecting node. A first set of network performance data associated with the communication connection is obtained. Ones of a plurality of diagnostic rules is automatically evaluated based on the obtained first set of network performance data to identify a second set of network performance data to be collected.
