Data-driven intelligent networking systems and methods are provided. The system can accommodate dynamic traffic with fast, effective congestion control. The system can maintain state information of individual packet flows, which can be set up or released dynamically based on injected data. Each flow can be provided with a flow-specific input queue upon arriving at a switch. Packets of a respective flow can be acknowledged after reaching the egress point of the network, and the acknowledgement packets can be sent back to the ingress point of the flow along the same data path. As a result, each switch can obtain state information of each flow and perform flow control on a per-flow basis.

Methods and systems are provided to facilitate network egress fairness between applications. At an egress port of a network, an arbitrator can provide fairness-based traffic shaping to data associated with applications. The desired fairness-based traffic shaping can be provided based on bandwidth, traffic classes, or other parameters. Consequently, the egress link's bandwidth can be allocated with fairness among the applications.

Embodiments relate to the management of data traffic congestion in a network communication node, the network communication node comprising a queue buffer configured to respectively enqueue packets at an input and dequeue packets at an output, and an Active Queue Management (AQM) module configured to determine a drop or a mark decision for a packet based on control parameters, wherein values for the control parameters are derived based on values of queue parameters weighted with respective weight factors and their associated target values, values of queue parameters and their associated target values weighted with respective weight factors, or a combination thereof.

A switch is provided, which can receive a data communication at an edge of a network. The network may be made up of a plurality of switches. The switch may generate a flow channel based upon an identified source and destination for the data communication. The data communication can be routed across the plurality of switches based on minimizing a number of hops between a subset of the plurality of switches and in accordance with the flow channel.

A network interface controller (NIC) capable of efficient packet injection into an output buffer is provided. The NIC can be equipped with an output buffer, a plurality of injectors, a prioritization logic block, and a selection logic block. The plurality of injectors can share the output buffer. The prioritization logic block can determine a priority associated with a respective injector based on a high watermark and a low watermark associated with the injector. The selection logic block can then determine, from the plurality of injectors, a subset of injectors associated with a buffer class and determine whether the subset of injectors includes a high-priority injector. Upon identifying a high-priority injector in the subset of injectors, the selection logic block can select the high-priority injector for injecting a packet in the output buffer.
