Patent Number: 
Section: abstract

A method, apparatus and computer product for modeling and analyzing performance of a Voice-over-IP (VoIP) configuration, composed of a plurality of components, is disclosed. The method comprises the step of representing selected ones of the plurality of components and relationships among the selected components, wherein said component representations are selected from the group of configuration non-specific representations consisting of: VoIP-DHCP Service, VoIP-CallOperation Service, VoIP_Signaling Service, VoIP_MediaGateway Service and VoIP_SIP Service, and wherein the representations of relationships are selected from the group of configuration non-specification representations consisting of: Hostedby/HostsServices and Integrates/IntegratedIn, providing a mapping between a plurality of first events and a plurality of second events occurring in the selected components, the mapping representing the relationships along which the first events propagate among the selected components, and determining at least one first event based on at least one of the plurality of second events by determining a measure between each of a plurality of relationship values associated with the plurality of first events and the plurality of second events.
