Abstract: A virtual network map view of all nodes is provided in a network which is representative of VoIP utilization of the network. As VoIP packets traverse elements of the network, information is stored or logged for use by a network management service. Combined with knowledge of the physical manifestation of the network, the virtual network map is created and used to manage the network as it relates to VoIP traffic. Other modeled devices such as routers, frame relay access devices (FRADs) and switches complete the picture by representing the logical virtual connections between nodes. A virtual link between communicating ICS devices is modeled, managed and configured independent of actual multiple and complex real interfaces or links.
