Patent ID: 8588063

Claim:
A method of providing resource admission control to packet flows associated with sessions in a communication network, the communication network handling packets according to priority levels assigned to the packets and the priority levels including at least a first and a second priority level, the method comprising: identifying a packet flow associated with a new session when packets of the packet flow enter the communication network; assigning the second priority level to the identified packet flow upon identifying the packet flow and handling said identified packet flow according to the second priority level, the first priority level being associated with an established session and the first priority level being of a higher priority level than the second priority level; measuring a congestion level in the communication network, the measuring the congestion level being based on monitoring congestion levels associated with all packet flows on the second priority level and the first priority level; if the measured congestion level stays below a threshold, upgrading the priority level of said identified packet flow associated with the new session from the second priority level to the first priority level; and handling said identified packet flow according to the first priority level within the communication network until the packet flow is terminated.
