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. Preferably, 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, thereby easing the progression from the analysis of output from one simulation to the generation of new input for a subsequent simulation.

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.

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： 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： Transactions within a transmission stream are identified that are related to an activity. The transactions are classified utilizing characteristics that identify the activity. Packets of the transaction are extracted from the transmission stream that corresponds to the activity. The extracted packets are presented in a visualization that identifies the packets and source and sink devices of the packets. The packets may be identified from a network trace. Classifying transactions includes identifying patterns present in packets to identify related transactions and/or packets that are temporally correlated. The characteristics may include heuristics related to a communication protocol of the transactions, examining temporal relationships of the packets, and/or identifying DNS requests related to the packets. The extracted packets may be presented as a tier pair circle wherein related devices are presented around a circumference of the tier pair circle and packet traffic between devices is indicated by a joining line.

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 system and method for determining a common time base among nodes in a network by iteratively propagating timing constraints among the nodes, and determining a time-shift to apply to the time base of each node that conforms to these constraints. “Trace” files record the time of transmission or reception of packets at each node, based on the time base at the node. A fundamental constraint in a common time-based system is that the time of reception of a packet at a destination node cannot be prior to the time of transmission of the packet from a source node. A further constraint in a common time-based system is that the time of reacting to an event cannot be prior to the time of the event. By concurrently tracing traffic among multiple nodes in a network and subsequently processing the trace files to assure that each packet's transmission occurs prior to its reception, and that each reaction packet occurs after its corresponding causal packet, a correspondence between each node's time base and the common time base can be determined.
摘要翻译：一种用于通过在节点之间迭代地传播时序约束来确定网络中的节点之间的公共时基的系统和方法，并且确定适用于符合这些约束的每个节点的时基的时移。 “跟踪”文件根据节点的时基记录在每个节点发送或接收数据包的时间。在通常的基于时间的系统中的基本约束是在目的地节点处接收分组的时间不能在来自源节点的分组传输时间之前。在通常的基于时间的系统中的进一步约束是对事件作出反应的时间不能在事件发生之前。通过同时跟踪网络中的多个节点之间的流量，随后处理跟踪文件，以确保每个数据包的传输在其接收之前发生，并且每个响应数据包在其相应的因果包之后发生，每个节点的时基与公共时基可以确定。

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.
