Abstract:
1. A method of operating a networked computer connected to a wide area network through a local network to determine a source of network performance degradation, the method comprising: tracking, during an interval of time, average network performance information for communications on a plurality of paths, wherein each path is between the networked computer and a device on the wide area network; obtaining network communication information from at least one other networked computer on the local area network; providing an indication that the performance degradation is caused by network cross traffic when the network communication information indicates that traffic on the local network is above a first threshold; providing an indication that a source of the performance degradation is access to the wide area network when the network communication information does not indicate that traffic on the local network is above the first threshold and the average network performance information indicates a performance degradation with communications associated with a number above a second threshold of the plurality of paths; and providing an indication that a source of the performance degradation is a device that is an endpoint of a path of the plurality of paths when the network communication information does not indicate traffic on the local network above the first threshold and the average network performance information indicates a performance degradation with a percentage of the plurality of paths that is below a third threshold.
