System and method for routing data on a packet network

A system for routing non-real-time content over a packet network, said system comprising:

• an input/output (I/O) unit in communication with a packet network and configured to receive a call request to communicate data packets including non-real-time content over a packet network;
• a processing unit in communication with said I/O unit and configured to:
• determine at least one network node over which a call path for a call to be established for the call request is to be routed;
• access network performance information associated with communications over the at least one network node, the network performance information includes real-time bandwidth usage and non-real time bandwidth usage;
• determine whether the at least one network node is impaired or congested;
• if the at least one network node is determined to be impaired or congested, determined the real-time bandwidth usage and the non-real time bandwidth usage from the network performance information;
• and
• if the at least one network node is determined to be impaired or congested then the at least one network node alters communication of the data packets including the non-real-time content and modifies the real-time bandwidth usage by decreasing the non-real time bandwidth usage based on the network performance information, service level agreements, and quality of service guarantees with each of a plurality of customers;
• otherwise, establish the call on the at least one network node.
