Abstract

A method, computer program product, and data processing system for establishing high-availability of network resources through automatic failover, while cooperating with existing telecommunications equipment management and other systems is disclosed. Events are filtered through a series of software modules, each having a particular role to play with respect to the event. External systems may register with a 'Notification Dispatcher' module, included within the series of modules, to receive notifications when particular events occur. In this way, conflicts between the high-availability system and other systems are avoided through well-defined sharing of information and delegation of responsibilities. Other modules may include 'Resource Agents' and a 'Resource Agent Adapter' for performing monitoring and control functions with respect to individual resources through a unified interface, a 'Node Failover Manager' for actually performing an automatic failover, and a 'Failover Rules Engine' for intelligently deciding when a given resource should experience a failover.
