    摘要： A system for collecting and aggregating data from network entities for a data consuming application is described. The system includes a data collector layer to receive network flow information from the network entities and to produce records based on the information. The system also includes a flow aggregation layer fed from the data collection layer and coupled to a storage device. The flow aggregation layer receiving records produced by the data collector layer and aggregates received records. The system can also include an equipment interface layer coupled to the data collector layer and a distribution layer to obtain selected information stored in the storage device and to distribute the select information to a requesting, data consuming application.

    摘要： A data collection system includes a plurality of node host computers. Each node host computer has a node manager, at least one processing node and a data manager. The data manager delivers network records between processing nodes. The processing nodes include an input queue and an output queue. In some embodiments at least one of the nodes has a plurality of output queues. The processing nodes are arranged in configurable chains of processing nodes. The chains are disposed across one or more of the plurality of host computers to process network records. The at least one processing node having the plurality of output queues can couple records from the plurality of output queues to input queues of corresponding processing nodes, based on a selected distribution method and/or selected content of records. The system can include an administrative client that displays a graphical user interface and an administrative server communicating with the node host computers and the administrative client. The administrative server stores files of executable code that can be dynamically downloaded from the server to configure the client and change the graphical user interface dynamically while the graphical user interface is running. A node deletion process is also described.

    摘要： Apparatus and method for learning current network behavior and predicting future behavior which utilizes a state transition graph. The graph includes nodes which represent network states, and arcs which represent trends in observable network parameters that result in a transition from a current state to another state. For example, a watch service may be instituted on multiple ports of a router, and the observed network traffic on the ports over time may be transformed into a state transition graph that represents network behavior. The network states may be labeled such as "good", or "bad", etc., according to a predetermined performance criteria. Once a state transition graph is constructed, the system may then monitor the current state and current trends of the network parameters in order to predict and display future network states. The system may include an automatic warning signal for alerting a user that the network is headed in the direction of a problematic state. The prediction of future network behavior may be made from the state transition graph, the current state of the network, and the current network trends.

    摘要： In a communications network, a request manager simultaneously dispatches a number of requests to servers corresponding to at least one domain of interest that is specified by a client. Multiple responses are received and a single collated response is sent back to the client that initiated the request. A request context table is provided which includes an anchor context and dependent contexts corresponding to each of the servers, and a session count for tracking receipt of all responses for each server. An internal cache of server addresses is also maintained.
