1. A method of determining a state of a path in a network, the method comprising:

  • observing at a network node of the network a rate of throughput over a time interval for at least a portion of the path;

    determining, at the network node of the network, derivations associated with a characteristic of at least one of frames and traffic flows that are communicated over at least the portion of the path;

    determining a state of congestion of the path in response to the observed rate of throughput as compared to a bandwidth profile of the path and the derivations; and

    determining a dynamic bandwidth profile through the network node using the derivations.
