Abstract: Methods, apparatuses and systems for diagnosing network anomalies and allocating repair resources in a computer network receive network anomaly reports (NARs) from a group of customers. Each NAR specifies a network anomaly observed by a customer at a network endpoint. Each NAR is entered into a database and associated in the database with attributes including at least one customer attribute associated with the sender of that NAR or network attribute associated with the network anomaly specified in that NAR. A time period is detected during which the difference between an aggregate number of NARs received within that time period and a baseline number of NARs received during prior time periods of substantially identical duration exceeds a threshold. The attributes associated with the NARs received during the time period are analyzed to identify a network anomaly specified in those NARs. Repair resources are further preferentially allocated to the identified network anomaly.

Abstract: A method for analyzing performance of a network, e.g., a communications network, is provided. In one embodiment, the method includes measuring detailed information relating to packet delays in routers and reporting the gathered information, for instance, using Simple Network Management Protocol (SNMP). The method hereof provides insight into through-router delays, such insights being particularly useful, for instance, for network providers who may have to comply with allowable delay statistics values across the domains they control.
