The value of a network lies in the business services that it provides. The goal of network management is ensuring the availability of these services. While the physical management task entails examination and repair of physical components, it is impossible to effectively maintain these components without explicit representation of services provided and consumed.We present a layered architecture for managing network value. The heart of this architecture is a service model based on a dependency graph whose nodes represent managed objects and edges represent service relationships. Events generated at lower layers of the architecture identify operational state changes in managed objects. These state changes may give rise to alarms that can be viewed at higher (presentation) layers.States propagate from one managed object to another where the service dependency graph identifies a behavioral dependency. Events and alarms representing impacts of a fault elsewhere correlate to the faulty component, focusing attention on root cause faults. Common semantics for expressing managed object state and service dependency allow the use of shared fault management techniques for all levels of abstraction.The presentation layer employs both linear and planar views, facilitating shifting between narrow preoccupation and contextual exploration. A rich filtering capability facilitates effective presentation to different audiences. This architecture has been partially implemented in the commercial Trinity product.

Abstract. Reported in this paper is the developed PMS, a PVC management system for ATM networks. PMS provides a scalable, end-to-end path management solution required for managing today's complex ATM networks. It aims to assist the network operators to perform PVC operations with simplified procedures and automatic optimum route selection. It also aims to provide effective decision-making support for PVC fault identification and prevention to the network operators.

“…The event correlation model described in the previous sections is implemented in IMPACT, a general-purpose telecommunication network alarm correlation system (Jakobson and Weissman, 1993;Jakobson, Weihmayer, and Weissman, 1994). As an example of a specific implementation of the correlations discussed in Section 2.3, we will refer to the event counting correlation.…”

Event correlation is becoming one of the most central techniques in managing the high volume of event messages. Practically, no network management system can ignore network surveillance and control procedures which are based on event correlation. The majority of existing network management systems use relatively simple ad hoc additions to their software to perform alarm correlation. In these systems, alarm correlation is handled as an aggregation procedure over sets of alarms exhibiting similar attributes. In recent years, several more sophisticated alarm correlation models have been proposed. In this paper, we will expand our knowledge-based event correlation model to capture temporal constraints.
