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.
