摘要： The invention is directed to techniques for monitoring and testing publish/subscribe network systems. For example, an enterprise network that has a number of geographically dispersed network devices and interconnected sub-networks may be configured to operate as a publish/subscribe network system in which each of the dispersed network devices sends and receives messages for specific groups of the network devices. The techniques described herein enable data object capture and analysis in the application layer of a publish/subscribe network system using shim adapters. The techniques also enable network packet capture and analysis in the network layer of a publish/subscribe network system. Furthermore, the techniques include integrated analysis of testing results from the application layer and the network layer to determine performance characteristics, such as latency, across both of the layers. In this way, the techniques provide more accurate measurements of performance characteristics in publish/subscribe network systems.

摘要： A system is described for monitoring and testing computer networks, such as enterprise networks that tend to have a number of geographically dispersed devices and interconnected sub-networks. The system includes a plurality of distributed agents coupled to a computing network. The system further includes a replay module coupled to the network that has a storage medium to store replay data. The replay module communicates respective portions of the replay data to the agents, and issues commands to the agents to control introduction of the network packets on the computing network by the agents. In this way, the system recreates network activity in order to test the computer network. The replay data stored by the storage medium may define a conditional flow for introduction of the network packets by the agents. Accordingly, the replay module may issue commands to the agents in accordance with the conditional flow.

摘要： A system is described for monitoring and testing enterprise networks that tend to have a number of geographically dispersed devices and interconnected sub-networks. The system includes a plurality of distributed agents to capture packets from a network. The system further includes an aggregation module coupled to the network to receive and aggregate the captured packets. During the aggregation process, the aggregation module identifies duplicate packets that were captured by different agents as an originating packet traverses the network. A display is coupled to the aggregation module, presents the non-duplicate network packets, giving a user a clear illustration of network activity. For the duplicate packets, the aggregation module presents a representative packet, such as the originating packet, that may be expanded by the user to view the details of the duplicate packets.
