Configuration management of managed objects is performed based upon performance data. Configuration management is performed on varying levels according to the amount of interpretation of the performance data that is required. A new configuration for an object is determined based upon the performance data, and the object is reconfigured according to the new configuration. Analysis may be performed at varying levels by a reactive analyzer and a deliberative analyzer.

Apparatus and method for distributed object filtering of objects transferred between a client and server. The objects may be alarms transferred between a network management server and one or more network management applications. The apparatus and method further includes applying a plurality of policy-based filters to the alarms. The filters may be named and stored in a database, and application of the policy-based filters may be scheduled for different times. The same policy-based filters may be applied to one or more multiple network management applications. The system and method provides increased performance and reliability of passing objects from a server to a client application.

A system and method is provided for managing information. Information is aggregated from multiple data sources into a data warehouse wherein the information can be provided to software applications. Disparate information from multiple sources is processed and stored in the data warehouse. Processing may include filtering, collation, compression, and mapping information into database fields of the warehouse. In one aspect, information stored in the warehouse may be network management data.

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 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.

Network capacity evaluation and planning is performed based upon the traffic across the links of the network. Once a link's traffic volume has been measured, it is compared with the link's traffic capability, and the resulting parameters compared with the traffic and capability of other links of the network to create measures of network capacity and balance. Then, simulated changes to the network configuration may be made by substituting simulated traffic volume amounts and capabilities for selected link traffic measurements and capabilities, and the resulting measures of network capacity and balance may then be compared to determine whether the simulated changes represent a preferred network configuration.

Buffer element for communication network, including a first buffer memory to store communication units corresponding to a first quality of service (QOS) level, and a second buffer memory to store communication units corresponding to a second quality of service level. A buffer manager selectively stores communication units from the first and second buffers based on the corresponding quality of service level, and retrieves communication units from the first and second buffer memories. The buffer manager includes a sorter unit for selectively storing based on the quality of service level. The buffer element may further include a depth adjuster to adjust the depth of the first and second buffer memory.

Fault management and recovery in a distributed network accounting system includes classifying nodes in the system according to complexity of processing in the node. For nodes of relatively low processing complexity, context check-pointing a state of processing in the nodes to permit automatic recovery of the node to the nodes' most recent processing context checkpoint; and for nodes of relatively high complexity, producing a directed graph of the programmable nodes that controls a flow of data and control of processing through the system, and producing a dynamic modification of the directed graph to automatically fail-over to redundant back-up nodes based on thresholds established for the component hosts.
