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： The present invention relates to a system and method for assessing application performance and user satisfaction. In one embodiment, the system and method calculates an Operational Index (OPdex) representing user satisfaction with an application. The OPdex may be a number quantifying user satisfaction with an application, such as a web application, and system performance. The OPdex may be based on one or more measurable metrics having a range of values that may affect user satisfaction or performance of an application. The OPdex may comprise calculating the index based on a soft threshold, a hard threshold, and measurements indicating a perceived application response time. The OPdex calculation may also account for sensitivity of user satisfaction to response time. Based on the OPdex, the system and methods also provide information indicating the relationship among application response time thresholds set by the users, the user satisfaction level, and the mean response time.

摘要： A hybrid approach to populating forwarding tables in a virtual network obtains forwarding data both by simulating routing protocol behavior in the virtual network to build forwarding tables, and by importing operational forwarding data from corresponding physical nodes in a physical network. The use of operational forwarding data improves the fidelity of the simulation by closely conforming forwarding behavior in the simulation to that which occurs in the physical network.

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： 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： The present invention relates to a system and method for assessing application performance, in some embodiments, the analysis considers external factors, such as business hours, time zone, etc., to identify or recognize distinctive intervals of application performance. These distinctive intervals correspond to different periods of activity by an enterprise or business and may occur in a cyclical manner or other type of pattern. The distinctive intervals defined by external factors are employed in the analysis to improve aggregating of statistics, setting of thresholds for performance monitoring and alarms, correlating business and performance, and the modeling of application performance. The metrics measured can include, among other things, measures of CPU and memory utilization, disk transfer rates, network performance, queue depths and application module throughput. Key performance indicators, such as transaction rates and round-trip response times may also be monitored.
