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 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： The locations of nodes in a network are determined relative to the location of monitoring devices that collect trace information on the network. By appropriate sorting, filtering, and characterizing the trace information, nodes are identified as being local to or remote from each monitoring device that detects traffic to or from the node. If the trace information is insufficient to determine the relative location of a node, the node is identified as such. By identifying the nodes whose locations can be determined automatically by this analysis of the trace information, the number of nodes whose locations must be determined by more costly manual methods can be substantially reduced.
摘要翻译：网络中节点的位置是相对于在网络上收集跟踪信息的监控设备的位置确定的。通过适当地排序，过滤和表征跟踪信息，节点被标识为检测到或来自节点的流量的每个监控设备的本地或远程。如果跟踪信息不足以确定节点的相对位置，则节点被识别为如此。通过识别可以通过对跟踪信息的分析来自动确定其位置的节点，可以大大减少其位置必须由更昂贵的手动方法确定的节点数量。

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.
