High speed and robust event correlation

The authors describe a network management system and illustrate its application to managing a distributed database application on a complex enterprise network.

Semantic Modeling of Managed Information

This paper presents a preliminary report on a semantic model of managed information, ERC. This model enriches the traditional Entity-Relationship (E-R) model with object oriented abstractions, constraints and event-correlation information. The model has much more expressive power than the CMIP management information model, (which in turn is more expressive than SNMP’s model), yet is simpler overall, and is more efficient to implement. It is thus particularly suitable for supporting complex event management systems. The paper presents the model, illustrates it through example applications, and briefly describes an efficient, protocol-independent implementation of the model used in a distributed management system.
