A system for determining packet quality on an Internet protocol-based (IP-based) network includes a packet test device that traces multiple paths on the IP-based network to obtain node identifiers corresponding to nodes on each path, and an Internet quality monitor (IQM) that associates a quality metric with each path, and associates an identified link between nodes in a path with one of the quality metrics. A method for monitoring quality of data on an Internet protocol (IP)-based network includes deriving a network topology corresponding to a portion of the IP-based network, determining a quality metric associated with a path in the network topology, deriving a link in the path, and determining a quality metric associated with the link based on the quality metric associated with the path.
