摘要： A user interface to a network simulator facilitates the use of application layer parameters and application layer logic. The user interface is configured to allow the user to define the input in a graphic form, or a text/programming form, or a combination of both. The user interface provides common graphic forms for both inputting the data to the simulator as well as for displaying the resultant data from the simulator. In response, the simulator and user interface may provide updated information to reflect the impact of changes made to application layer parameters and logic.

摘要： Individual network activities are correlated to interactions with a target web page to facilitate an analysis of the performance of the web page. This correlation is preferably performed using a combination of heuristics and rules developed to filter network activities into those activities that are likely to have been caused by the particular transaction, and those that are unlikely to be associated with that transaction. The activities that are identified as being associated with the transaction are subsequently organized to identify a time-flow of these activities within the transaction, from which performance statistics can be determined and presented to a user. Because the individual activities within the transaction are identified and time-ordered, an analysis of the effects of each activity on the overall performance of the web page can be performed to identify potential problem areas, or to diagnose reported problems.

摘要： A network analysis system provides for a user-definable display of information related to messages communicated on the network. The network analysis system includes one or more display formats that provide a display of message exchanges between nodes of a network, and a display augmenter that provides additional information on the display based on a user-defined visualization. The user defined visualization includes augmenting the display based on user-defined coloring characteristics and/or augmenting the display with user-defined labels. To further facilitate user control of the augmentation of the display, the system accepts user-defined programs for discriminating among messages, for controlling the labeling of messages, and for controlling the coloring of messages and labels. Commonly used user-defined characteristics and labels are stored in a library, for use via a selection from among the library entries.

摘要： A system and method for managing captured network traffic data is provided. The invention comprises a plurality of capture agents, each being configured to capture the network traffic associated with one or more applications. Each application is associated with one or more capture agents according to an application profile that is stored and maintained in a capture server. When analysis of an application's network traffic is required, the capture server contacts the corresponding capture agents according to the application profile. The capture server then effects the identification and archiving of the network traffic that corresponds to a user-defined capture condition. A database at the capture server maintains a record that associates the corresponding network traffic with the user-defined capture condition such that the corresponding network traffic can later be retrieved and analyzed using an analysis engine.

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 determines correlations within multi-tier communications based on repeated iterations/episodes of executions of a target application. Content-based correlations are determined by encoding the content using a finite alphabet, then searching for similar sequences among the multiple traces. By encoding the content to a finite alphabet, common pattern matching techniques may be used, including, for example, DNA alignment algorithms. To facilitate alignment of the traces, structural and/or semantic breakpoints are defined, and the encoding in each trace is synchronized to these breakpoints. To facilitate efficient processing, a hierarchy of causality among tier-pairs is identified, and messages at lower levels are ranked and temporally filtered, based on activity intervals at higher levels of the hierarchy.

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： Time-varying latency is estimated based on the round-trip time between the time of sending a message and the time of receiving an acknowledgement of receipt of the message. The round-trip time relative to a transmitter is modeled as a combination of known, or determinable, delays, plus an unknown latency, plus a processing/acknowledgement delay at the receiver. The estimated time-varying latency is further refined to give more weight to estimates based on fewer unknowns or a lesser magnitude of unknowns, and to impose physical constraints, such as assuring that the estimate does not imply an unrealizable event. TCP-specific constraints and assumptions are also applied to further refine the latency estimates.

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： Performance metrics related to the processing and propagation of messages related to select applications are collected during a simulation of a network. Each message associated with an application is tagged, and each simulated packet that contains some or all of a tagged message is correspondingly tagged to facilitate the creation of transmit records and receive records. A post processor is configured to collate transmit and receive records of each tagged message to identify delays associated with each node that processes the message, and each link that propagates the message from node to node within the network. The processed timing information is provided to the user via an interactive user interface that allows the user to view the timing information from an application layer perspective.
