摘要： 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.

摘要： The present invention relates to managing data generated by software transactions, such as event tracing software. In one embodiment, data generated by event tracing software is monitored. The throughput of the data generated may then be modulated based on various criteria, such as a target data rate. The throughput target may be specified on a per-system basis or individual basis. Based on the throughput, the level of detail recorded is modulated. Individual processes may determine a limit or quota depending on their contribution to the throughput. In one embodiment, the method calls for a trace are modified with different property specifications to meet a desired throughput of event tracing data.

摘要： The present invention relates to correlating requests between a client and a server to a particular transaction. In one embodiment, transactions in a system of clients and servers are monitored and traced. From this information, a context comprising sets or groupings of transaction call sequences are determined. For example, a sequence of method calls on a client process is traced to a socket carrying data for transmission of a request message to a server. In response to this request message, the server then executes a set of method calls that can be correlated to the request message and the socket. This set of actions is considered part of a causally related grouping, and thus, associated together. In one embodiment, HTTP requests from a client may be comprise a unique custom header that is readily identified and traced. For other protocols, a client socket is associated with a corresponding server socket or to data received over a socket receive call.

摘要： A network capture element is embodied on a virtual machine, and a utility function is embodied on the actual device, preferably within the virtual machine manager. Both the utility function and the traffic capture element are configured to monitor communication events. To minimize the overhead imposed, the utility function is configured to merely store the time that the event occurred on the actual machine, corresponding to an identifier of the event. The network capture element, on the other hand, performs the time consuming tasks of filtering the communications, selectively storing some or all of the data content of the communications, characterizing the data content, and so on. Instead of storing the virtual time that the communication event occurred at the virtual machine, the network capture element uses the identifier of the communication event to retrieve the actual time that the communication event occurred on the actual machine.

摘要： An interactive system and method automates the control and management of routing changes that are focused on specific routes or particular network hot spots. Based on the premise that the user is aware of a particular problem that needs to be solved, the system leads the user through an end-to-end process from the identification of the problem to the generation of configuration instructions for effecting a selected solution. A graphic user interface provides a visualization of the current routing and alternative routings, to facilitate the analysis and selection of an improved routing, if any. Throughout the process, the effect of each proposed routing change on the overall network performance is determined, so that the selection of a preferred solution can be made in the appropriate context, and globally sub-optimal solutions can be avoided.

摘要： Traffic flows through an administered network from an off-network source and/or to an off-network destination are simulated and analyzed by selecting an ingress and/or egress node within the administered network, the ingress node capable of collecting traffic from an off-network source, and the egress node capable of routing traffic to an off-network destination. Traffic flow is mapped from the source or ingress node through the administered network to the egress node. The traffic flow may be simulated and analyzed. The ingress and/or egress nodes may be selected in a variety of ways.

摘要： Embodiments provide systems, methods, and computer program products for inferring the switch port connectivity of discovered but. unmanaged devices in a network without direct access to the devices. Embodiments operate by generating a physical address-to-port map based on collected operational data and then pruning the generated map based on switch port connectivity information and/or inferred link connectivity information. The switch port connectivity of discovered unmanaged devices is then generated or updated based on the pruned map. The switch port connectivity information can be used by various other tools to enable diagramming, asset inventory, and network planning, design, and optimization workflows.

摘要： Embodiments for quick network path discovery are provided. Embodiments may be used by a user (e.g., network administrator) in troubleshooting a performance/communication problem in the network. M an embodiment, path information, including Layer-3 and/or Layer-2 path information, can be requested between any pair of devices in the network and presented to the user. In an embodiment, path information is provided to the user in an iterative (or gradual) manner as soon as resolved. This allows the user quick access to path information, which both reduces troubleshooting time and enhances the user experience. In addition, in an embodiment, the path information may be provided without any live interaction with any device in the network.
