Abstract:
1. A method for routing content over a packet network, the method comprising: receiving a call request at a call control manager to communicate data packets including real-time content and non-real-time content over a packet network; determining at least one network node through which a call path for a call is to be routed; accessing network performance information associated with communications over the at least one network node, the network performance information including real-time bandwidth usage and non-real time bandwidth usage; automatically determining whether the at least one network node is impaired or congested; in response to a determination that the at least one network node is impaired or congested, determining the real-time bandwidth usage and the non-real time bandwidth usage from the network performance information, altering by the at least one network node, communications of the data packets including the non-real-time content to modify the real-time bandwidth usage by decreasing the non-real time bandwidth usage based on the network performance information; in response to a determination that the at least one network node is not impaired or congested, establishing the call through the at least one network node; determining priority of the call request; if the call request has a priority above a threshold value, establishing the call through the at least one network node; and if the call request has a priority below another threshold value, dropping the call through the at least one network node.
