Abstract: A network switch includes multiple data crossbars and multiple header planes for controlling the data crossbars. In an example implementation, a device includes: a plurality of header planes, each of the header planes including an input queue, an output queue, a request crossbar connected to the input queue and the output queue, and a grant crossbar connected to the input queue and the output queue; a receiver; and a header plane selector. The header plane selector is configured to: receive a transfer request for a packet from the receiver; select a header plane of the header planes based on a header of the packet; and queue the transfer request at the input queue of the header plane.

Abstract: The efficient storage of transformation information in a switch is provided. A respective port of the switch can include a memory device capable of storing transformation information. During operation, the switch can apply a selection mechanism to the transformation information learned at the switch for identifying a target port. The switch can then store the information in the memory device of the target port. Upon receiving a packet, the ingress port can apply the selection mechanism to the header information of the packet for determining a location of a first piece of transformation information associated with the packet. The ingress port can obtain the first piece of transformation information by looking up the header information in the location and storing it in a local memory device. The ingress port can then transform the packet based on the first piece of transformation information for determining an egress port for the packet.

Abstract: A network switch has a packet pulling architecture, and also supports packet pushing. In an example implementation, a device includes: an output buffer; a data crossbar connected to the output buffer; an input buffer connected to the data crossbar; an input queue; a request crossbar connected to the input queue; and an output queue. The input queue is configured to transfer a packet from the input buffer to the output buffer over the data crossbar in response to the packet being eligible for packet pushing, and to send a push request in parallel with transferring the packet to the output buffer. The output queue is configured to receive the push request from the input queue over the request crossbar, and to control reading of the packet from the output buffer in response to granting the push request

Abstract: A switch architecture for a data-driven intelligent networking system is 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 are acknowledged after reaching the egress point of the network, and the acknowledgement packets are 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.
