Abstract: A method for data flow rate detection useful with data flow rate control is introduced into a TCP packet communication environment which does not have data rate supervision by computing presumed speed based on latency between packets during initial interchange of synchronization (SYN) packet and the acknowledgement (ACK) packet, presuming to know the initial length of each. This information may be utilized to determine potential rate of data flow for further use in making bandwidth allocation and rate enforcement decision.

Abstract: In a packet communication environment, a method is provided for classifying packet network flows for use in determining a policy, or rule of assignment of a service level, and enforcing that policy by direct rate control. The method comprises applying individual instances of traffic objects, i.e., packet network flows to a classification model based on selectable information obtained from a plurality of layers of a multi-layered communication protocol, then mapping the flow to the defined traffic classes, which are arbitrarily assignable by an offline manager which creates the classification. It is useful to note that the classification need not be a complete enumeration of the possible traffic. 00000

Abstract: A data and control plane architecture for network devices. An example system architecture includes a network processing unit implementing one or more data plane operations, and a network device operably coupled to the network processing unit that implements a control plane. In a particular implementation, the network processing unit is configured to process network traffic according to a data plane configuration, and sample selected packets to the network device. The network device processes the sampled packets and adjusts the data plane configuration responsive to the sampled packets.

Abstract: A method for explicit data rate control is introduced into a packet communication environment (10) which does not have data rate supervision by adding latency to the acknowledgement (ACK) packet and by adjusting the size of the flow control window associated with the packet in order to directly control the data rate of the source data at the station (12 or 14) originating the packet.
