    • 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.
    • 个人网络活动与与目标网页的交互相关联,以便于分析网页的性能。 该相关性优选地使用启发式和为了将网络活动过滤到可能由特定交易引起的那些活动而开发的规则以及不太可能与该交易相关联的那些活动的组合来执行。 被识别为与事务相关联的活动随后被组织以识别事务内的这些活动的时间流,从中可以确定并呈现性能统计信息给用户。 由于事务中的各项活动被识别并且被定时,因此可以对每个活动对网页整体性能的影响进行分析,以识别潜在的问题领域,或者诊断报告的问题。

    • 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.
    • 网络分析系统提供与在网络上传送的消息有关的信息的用户可定义的显示。 网络分析系统包括提供网络节点之间的消息交换的显示的一个或多个显示格式,以及基于用户定义的可视化来在显示器上提供附加信息的显示增强器。 用户定义的可视化包括基于用户定义的着色特征增强显示和/或用用户定义的标签来增加显示。 为了进一步促进用户对显示器增加的控制,系统接受用户定义的程序,用于区分消息,用于控制消息的标注,以及控制消息和标签的着色。 通常使用的用户定义的特征和标签存储在库中,以便通过库条目中的选择使用。

    • 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.
    • 提供了一种用于管理捕获的网络流量数据的系统和方法。 本发明包括多个捕获剂,每个捕获剂被配置为捕获与一个或多个应用相关联的网络流量。 每个应用程序根据存储和维护在捕获服务器中的应用程序配置文件与一个或多个捕获程序相关联。 当需要分析应用程序的网络流量时,捕获服务器将根据应用程序配置文件与相应的捕获代理进行联系。 然后,捕获服务器对与用户定义的捕获条件相对应的网络流量进行识别和归档。 捕获服务器上的数据库维护一个记录,将相应的网络流量与用户定义的捕获条件相关联,以便随后可以使用分析引擎检索和分析相应的网络流量。

    • 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.
    • 多功能图形用户界面便于分析和评估应用程序延迟,包括在多条路径上发生的延迟。 对应用程序的网络事件的跟踪文件进行处理,以分类这些事件的传播和处理所引起的延迟的原因。 该系统通过消除单独的延迟的每个分量以及可以通过消除延迟的组合来消除的延迟量(“并行延迟”)来识别可以消除的延迟量(“分量延迟”) 组件。 用户界面显示通过单独消除每个组件延迟可以实现的减少量以及通过消除单个组件延迟的组合可以实现的减少量。 为了便于分析和评估这些潜在的减少,界面允许用户“向下钻取”以查看形成并行延迟的每个组合中包含的各个延迟组件。 以这种方式,向用户提供需要单独地或组合地需要寻址的每个延迟组件的视图,以改善整体应用延迟。

    • 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.
    • 网络捕获元件体现在虚拟机上,并且效用函数体现在实际设备上,优选地在虚拟机管理器内。 效用功能和流量捕获元件都配置为监视通信事件。 为了最小化所施加的开销,效用函数被配置为仅存储事件在实际机器上发生的时间,对应于事件的标识符。 另一方面,网络捕获元件执行过滤通信的耗时任务,选择性地存储通信的一些或全部数据内容,表征数据内容等等。 网络捕获元件不是存储通信事件在虚拟机中发生的虚拟时间,而是使用通信事件的标识符来检索在实际机器上发生通信事件的实际时间。

    • 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.
    • 系统/方法在业务流中搜索与“参考”分组的序列呈现高度相关性或相似性的“匹配”分组序列。 匹配和参考分组之间的相关性基于各个分组之间的对应程度以及相应分组的顺序。 Needleman-Wunsch算法的变体优选地用于基于每个匹配的对应度的度量来选择提供与参考分组的序列顺序最佳匹配的序列顺序的业务流中的相应分组,以及 与每个不匹配相关的罚款。 该算法被进一步修改以减少用于在流量流中找到相应分组的所需搜索空间。
