A network analysis system invokes an application specific, or source-destination specific, path discovery process. The application specific path discovery process determines the path(s) used by the application, collects performance data from the nodes along the path, and communicates this performance data to the network analysis system for subsequent performance analysis. The system may also maintain a database of prior network configurations to facilitate the identification of nodes that are off the path that may affect the current performance of the application. The system may also be specifically controlled so as to identify the path between any pair of specified nodes, and to optionally collect performance data associated with the path.

Network path discovery and analysis

The embodiments improve the results of an auto-detection of network devices responsive to the causes of detection failures in preceding runs of the auto-detection process. The network may comprise various devices that are believed to be in the network. If a device that is believed to be in the network, but is undiscovered, the embodiments identify the device and information regarding the cause or causes of non-discovery. In response, the discovery parameters are modified, based on the causes associated with the undiscovered devices. The extent to which the discovery parameters are modified is based various criteria, such as the characterization of the network, or upon the detection of changes to the network.

Incrementally improved auto-discovery of network devices

A method and/or system is configured to improve the results of an auto-detection of network devices based on the causes of detection failures in preceding runs of the auto-detection process. As each device that is believed to be in the network is found to be undiscovered, the identification of the device and information regarding the cause(s) of non-discovery are stored. Prior to the next auto-detection run, one or more of the discovery parameters are modified, based on the causes associated with the undiscovered devices. The extent to which the discovery parameters are modified is preferably based on the apparent stability of the network, or upon the detection of changes to the network.
