A method of determining the state of a path in a network. A rate of throughput is observed at a node of the network over an interval for at least a portion of the path. Derivations associated with a characteristic of the frames or traffic flows communicated over at least the portion of the path are determined at the node. A state of congestion of the path is determined in response to the observed rate of throughput as compared to a bandwidth profile of the path and the derivations.
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 a
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; anddetermining a dynamic bandwidth profile through the network node using the derivations. 2. The method of claim 1, wherein the traffic flows are determined for a number of devices. 3. The method of claim 2, wherein the number of devices are being monitored. 4. The method of claim 1, wherein the derivations includes an average packet size. 5. The method of claim 1, wherein the derivations include an average amount of non-payload bits of the frames received during the time interval. 6. The method of claim 1, wherein the derivations are an observed overall throughput in bits per second less a determined amount of non-payload bits per second. 7. The method of claim 1, wherein the state of congestion is used to control traffic over the network. 8. The method of claim 1, wherein the state of congestion is used by a call control manager to route telephone calls. 9. The method of claim 1, wherein the state of congestion is used by a call control manager to perform call set-up for telephone calls. 10.
