Patent ID: 7898970

Claim:
A method for determining one-way path performance in a network that includes a source route control device and a destination route control device, wherein the source route control device is connected to at least two source network service providers and the destination route control device is connected to at least one destination network service provider, so that there are a plurality of outbound paths from the source route control device to the destination route control device via the at least two source network service providers, comprising: determining an inbound path from the destination route control device to the source route control device, wherein the inbound path is associated with a selected one of the source network service providers and a selected one of the destination network service providers; probing each of the outbound paths to determine performance associated with each of the outbound paths by traversing each of the outbound paths from the source route control device to the destination route control device and traversing the inbound path, so that the inbound path is traversed for all outbound paths.
