Abstract: A virtual domain management system is provided which associates application, physical and virtual domains to enable propagation of events, symptoms and other information across the domains. The virtual domain manager collects events and symptom information across multiple domains by correlating domain topology models. Using a causality matrix and codebook technology the virtual domain manager uses the information to perform root cause and impact analysis across domains. Information from the analysis may be fed back into the domains to enhance domain management.

Abstract: A method and apparatus for logically representing and performing an analysis on a home network is disclosed. The method comprising the steps of representing selected ones of a plurality of components and the relationship among the components associated with the home network, providing a mapping between a plurality of events and a plurality of observable events occurring among the components, wherein the mapping is represented as a value associating each event with each observable event, and performing a system analysis based on the mapping of events and observable events. In another aspect of the invention, the home network is included in a larger system logically represented as a plurality of domains, wherein at least one of the plurality of components in the network is associated with at least two of the domains.
