A network management system includes a fault diagnosis engine, a topology mapper, an impact analyzer and a help desk system. The topology mapper includes a discovery module, a memory, and a presentation module. The discovery module is constructed and arranged to discover network elements in a communications network. The memory constructed and arranged to store topology data received from the discovery module. The presentation module constructed and arranged to present data related to topology of the communication network.

Systems and methods for constructing multi-layer topological models of computer networks

A system () for analyzing a fault includes a fault object factory () constructed and arranged to receive fault data and create a fault object (), and a fault diagnosis engine () constructed and arranged to perform root cause analysis of the fault object. The system may further include a fault detector () constructed and arranged to detect the fault data in a monitored entity, a fault repository () constructed and arranged to store and access the fault object; and a fault handler () constructed and arranged to be triggered by the fault diagnosis engine to analyze the fault object.

Systems and methods for managing and analyzing faults in computer networks

A network management system () includes a fault diagnosis system () connectable to a communications network (). The fault diagnosis system includes a fault object factory, a path determination module, and a fault diagnosis engine. The fault object factory is constructed and arranged to receive fault data and create fault objects. The path determination module is constructed to determine, in a communications network, a path related to the fault data. The fault diagnosis engine is constructed to perform, using the determined path, a fault analysis on the fault data to diagnose a fault related to the communications network. The network management may also include a help desk system (), a topology mapper () or an impact analyzer ().

Systems and methods for diagnosing faults in computer networks

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.
