Abstract
Examples relate to hierarchical switching devices comprising a plurality of sub-switches forming a fully interconnected all-to-all network. The sub-switches comprise internal input ports and internal output ports to exchange packets with other sub-switches within the fully interconnected all-to-all network. The internal input ports of the sub-switches have exclusive access to a queue partition for each external output port of the respective sub-switch. A switch controller receives a packet at a first sub-switch of the plurality of sub-switches that is to be routed to a particular external output port of a second sub-switch of the plurality of sub-switches. The switch controller routes the packet directly from the first sub-switch to the second sub-switch using an internal output port of the first sub-switch and a queue partition of the second sub-switch that is for the particular external output port of the second sub-switch.
