摘要： Application messages are segregated into message paths, and the delays of the transmitted packets associated with each message path are independently analyzed to distinguish propagation, bandwidth, congestion, and protocol delays. To further distinguish the congestion delays, all of the paths of the application messages are assessed to identify delays induced by the application, including self-congestion delay, corresponding to pre-congestion delays caused by attempting to send data from a source device faster than the bandwidth of the channel allows, and cross-congestion delay, corresponding to post-congestion delays caused by varying delays beyond a bottleneck link in the channel. The remaining congestion delay is identified as network congestion delay, corresponding to delays caused by network devices other than the source device. After identifying each of the components of delay, the effect of each component on the overall delay is determined to identify where improvements can best be made.

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： 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 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.

The system identifies the amount of delay that can be eliminated by eliminating each of the components of delay individually, as well as the amount of 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 various delays alone or in combination.

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 analysis 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.
