摘要： To evaluate a network's performance in processing communications related to a target transaction, a set of “reference” communications corresponding to the target transaction are compared to a larger set of communications in the network in a “production” environment, to identify the occurrence of the target transaction in the production environment. Preferably, the reference communications are recorded in a laboratory environment that models the production environment, or recorded from the production environment during a period of minimal other activities. A variety of filters are used to eliminate communications in the production environment that are apparently unrelated to the target transaction, including filters based on the time-order of communications among the nodes, the size of the packets being communicated, and the content of the communications. If necessary, after eliminating the apparently unrelated communications from consideration, the remaining production communications are compared to the reference communications to identify the most likely production communications corresponding to the reference communications.

摘要： A system/method searches a traffic stream for a sequence of “matching” packets that exhibit a high degree of correlation or similarity to a sequence of “reference” packets. The correlation between matching and reference packets is based on a degree of correspondence between individual packets, as well as the sequence-order of the corresponding packets. A variation of the Needleman-Wunsch algorithm is preferably used to select corresponding packets in the traffic stream that provide a sequence-order that best matches the sequence-order of the reference packets, based on a measure of the correspondence for each match, and a penalty associated with each non-match. The algorithm is further modified to reduce the required search-space for finding corresponding packets in the traffic stream.

摘要： Data representing application deployment attributes, network topology, and network performance attributes based on a reduced set of element attributes is utilized to simulate application deployment. The data may be received from a user directly, a program that models a network topology or application behavior, and a wizard that implies the data based on an interview process. The simulation may be based on application deployment attributes including application traffic pattern, application message sizes, network topology, and network performance attributes. The element attributes may be determined from a lookup table of element operating characteristics that may contain element maximum and minimum boundary operating values utilized to interpolate other operating conditions. Application response time may be derived using an iterative analysis based on multiple instances of one or more applications wherein a predetermined number of iterations is used or until a substantially steady state of network performance is achieved.

摘要： Application messages are segregated into message paths, and the delays of the transmitted packets associated with each message path are independently analyzed to distinguish propagation, bandwidth, congestion, and protocol delays. To further distinguish the congestion delays, all of the paths of the application messages are assessed to identify delays induced by the application, including self-congestion delay, corresponding to pre-congestion delays caused by attempting to send data from a source device faster than the bandwidth of the channel allows, and cross-congestion delay, corresponding to post-congestion delays caused by varying delays beyond a bottleneck link in the channel. The remaining congestion delay is identified as network congestion delay, corresponding to delays caused by network devices other than the source device. After identifying each of the components of delay, the effect of each component on the overall delay is determined to identify where improvements can best be made.

摘要： The embodiments facilitate the analysis of application delays, including delays that occur on multiple paths. A trace file of an application's network events is processed to categorize the causes of delays incurred in the propagation and processing of these events. The system identifies the amount of delay that can be eliminated by eliminating each of the components of delay individually, as well as the amount of delay that can be eliminated by eliminating combinations of the delay components. A user interface displays the amount of reduction that can be achieved by eliminating various delays alone or in combination. The interface also allows the user to view the individual delay components contained in combinations of delay components. In this manner, the user is provided a view of each of the delay components that would need to be addressed, either individually or in combination, to improve the overall application delay.

摘要： A first capture system that captures network communication events related to an application, and a second capture system that captures internal processing events related to the application. A visualization system analyzes the data captured by each of the capture systems, synchronizes and correlates the data, and presents an integrated display of these communication and processing events. In a preferred embodiment, the communicated messages include an identifier of the application, and the processing components also associate an identifier of the application to each recorded processing event. To facilitate the integrated display of the events, the visualization system synchronizes the recorded communication and processing events to a common time base.

摘要： A multi-functional graphical user interface facilitates the analysis and assessment of application delays, including delays that occur on multiple paths. A trace file of an application's network events is processed to categorize the causes of delays incurred in the propagation and processing of these events. The system identifies the amount of delay (‘component delay’) that can be eliminated by eliminating each of the components of delay individually, as well as the amount of delay (‘parallel delay’) that can be eliminated by eliminating combinations of the delay components. A user interface displays the amount of reduction that can be achieved by eliminating each component delay individually and the amount of reduction that can be achieved by eliminating combinations of the individual component delays. To facilitate the analysis and assessment of these potential reductions, the interface allows the user to ‘drill down’ to view the individual delay components contained in each combination forming the parallel delays. In this manner, the user is provided a view of each of the delay components that would need to be addressed, either individually or in combination, to improve the overall application delay.

摘要： A system and method for analyzing network traffic activity by displaying a collection of flow objects and receiving a user's selection of a traffic operation that is to be applied to a set of selected flow objects. Thereafter, the results of applying the traffic operation to the selected flow objects are displayed. The traffic operation may include a merge operation that provides statistics related to an aggregation of the flow objects. The traffic operation may also include a modification operation that modifies the selected flow objects, including, for example, a modification based on predicted traffic flow. Other traffic operations may also be provided, including providing access to plug-in traffic operation applications.
