Abstract:
Packet network node and method of operating packet network node. Conventional packet network nodes react to congestion in packet network by dropping packets in a manner which is perceived by users to be indiscriminate. In the described system, indiscriminate packet discards are prevented by causing packets to be discarded on lower priority flows and flow aggregates. Further action is taken to reduce the likelihood of packet discards through: (1) classification of flows that are not observable at the point in the network where flow-based packet discards are deployed, but are consuming bandwidth and signaling classification information to flow-based packet discard function or a flow-based monitoring function or network management function; (2) classification of flows making use of extended monitoring functions that are not co-located with a flow-based packet discard function, where extended monitoring functions may perform monitoring of a flow or a group of flows over a period of time.

Claim (Index 11):
A packet network node comprising:\n a) an input for receiving one or more packets; b) means to store a packet flow identifier corresponding to a packet flow, such that packets detected at the input are associated with a stored packet flow identifier or are determined to be a new packet flow; c) means to measure a packet flow rate or byte rate in the packet network node, relating to a packet flow or group of packet flows, and means to detect an excessive packet flow rate or the byte rate, including the use of any associated limits of the packet flow rate or jitter in the packet flow rate assigned to the packet flow or the group of packet flows; d) means to detect excessive bursts or jitter in the packet flow rate or the byte rate in the packet network node relating to the packet flow or the group of packet flows including the use of associated limits of burstiness or jitter assigned to the packet flow or the group of packet flows; e) means to retrieve policy information and QoS treatment determination associated with the packet flow identifier corresponding to a latest arriving packet, and determined through policy information and monitored information; and f) means to forward signals to, or receive signals from, Flow State Aware network functions via a packet subnet or through dedicated links, where the signals include the identity of the packet flow or the group of packet flows or packet flow aggregate together with the monitored information related to the identity of the packet flows or the groups of packet flows or the packet flow aggregate.
