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： 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： 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： Multiple parent-dependencies are identified for messages that are received on a network that includes nodes that are configured to avoid the conventional strictly-sequential communications techniques and protocols, in order to accelerate network performance. If a network is known, or assumed, to include intermediate/proxy nodes that are configured to provide acceleration, access control, and other services, the system that analyzes traffic on the network is configured to assume that these nodes may/will provide such features, and thereby introduce multiple dependencies among the messages communicated across the network. For each message transmitted from a forwarding node, messages received at the forwarding node are assessed to distinguish messages from the destination node and messages from an other node, and a dependency is defined for each.
摘要翻译：为在网络上接收的消息识别多个父依赖关系，该消息包括被配置为避免传统的严格顺序通信技术和协议的节点，以便加速网络性能。如果网络已知或假设为包括被配置为提供加速，访问控制和其他服务的中间/代理节点，则分析网络上的流量的系统被配置为假设这些节点可以/将提供这样的特征，从而在通过网络传送的消息之间引入多个依赖关系。对于从转发节点发送的每个消息，评估在转发节点处接收的消息以区分来自目的地节点的消息和来自其他节点的消息，并且为每个消息定义依赖关系。

摘要： In a network that includes intermediary nodes, such as WAN accelerators, that transform messages between nodes, an end-to-end path of the messages is determined. The determined end-to-end path is used in subsequent analyses of message traces, to identify timing and other factors related to the performance of the network relative to the propagation of these messages, including the propagation of the transformed messages. A variety of techniques are presented for determining the path of the messages, depending upon the characteristics of the collected trace data. Upon determining the message path, the traces are synchronized in time and correlations between the connections along the path are determined, including causal relationships. In a preferred embodiment, a user identifies an application process between or among particular nodes of a network, and the system provides a variety of formats for viewing statistics related to the performance of the application on the network.
