  • Characterizing application performance within a network
    Patent number: 7574504
    Abstract: A system and method are described for analyzing the performance of a network while processing an application. The method involves measuring and calculating the amount of time nodes are active processing and sending frames, as well as the amount of time that frames spend traversing the network. Graphical user interfaces are provided to effectively present significant measurements and calculations.

  • System and method of active latency detection for network applications
    Patent number: 7366790
    Abstract: A system and method of active latency detection for network applications that allows network latency to be calculated from a single host system. Periodic requests are generated from the host system and directed to a remote system in a way that requires minimal processing by the remote system. Latencies are calculated from the timing information associated with the periodic requests and can be combined with timing information associated with application packets to generate a latency trace for one or more network applications.
