Abstract: A path diagnosis method and system for a VoIP network includes obtaining information on VoIP calls from the VoIP network using either Call Data Records (CDRs) or active testing, or both. A VoIP call that has a problem is determined between a source and a destination device on the VoIP network, based on the obtained information. Likely call paths between the source and destination devices on the VoIP network are determined. The VoIP network is queried to obtain network data with respect to all devices that exist between the source and destination devices along the likely call paths. A path diagnostics chart is displayed that shows the devices that exist between the source and destination devices along the likely call paths, along with any call issues that exist for each of the devices.

Abstract: Network functional components made up of a set of network elements (routers, switches and other infrastructure devices) communicating and cooperating to implement a network service such as a routing protocol or the spanning tree used to implement VLANs, are assigned performance and/or health metrics, which are communicated through a communications device, such as a display or speaker. A “Correct” performance metric for each network functional component of the network indicates that functional network component's conformance to a set of programmed configuration standards, which typically represent best practices for the network. A “Stable” performance metric for each network functional component indicates the degree to which that network functional component is operating efficiently and effectively. By combining these performance metrics for the individual network functional components, for instance by averaging them, one can arrive at a single performance metric for the entire network.
