Abstract:
1. A method for routing a call, said method comprising: receiving from a first network a call request from a calling party to call a called party at a network address of a second network; determining a potential call path to connect the calling party from the first network to the called party at the network address of the second network; determining, using performance information packets (“PIP packets”) generated by network nodes along the potential call path, that the potential call path is impaired; accessing network performance information associated with a plurality of potential call paths, the network performance information gathered from PIP packets generated by network nodes along each of the plurality of potential call paths; determining a value associated with the potential call path by determining values representative of a slowest communication speed over each of the network nodes along the potential call path; in response to a determination that the value associated with the potential call path is indicative of performance issues related to the network nodes along the potential call path, determining a second potential call path over the packet network over which a call associated with the call request may be placed; accessing network performance information associated with each node segment on the second potential call path; determining a second value associated with the second potential call path, the second value being indicative of communications operations of network nodes along the second potential call path; assigning the second potential call path to the call based on the determined value in response to a determination that the determined second value is below a threshold value indicative of the second potential call path being unimpaired and uncongested; and routing the call over the second call path to enable the calling party to communicate with the called party at the network address of the second network.
