Abstract
A method for detecting and isolating domain specific faults includes comparing a first media quality report for a communication from a first node with a second media quality report for the communication from a second node. The first node comprises an ingress node of a first domain for the communication and the second node comprises an egress node of the first domain for the communication. The method also includes determining that the difference between at least one aspect of the first media quality report and at least one corresponding aspect of the second media quality report exceeds a first threshold. The method further includes, upon determining that the difference exceeds the first threshold, determining a first path between the first node and the second node used by the communication. The method additionally includes isolating at least one source causing the difference between the first media quality report and the second media quality report.
