Abstract
Apparatuses, methods and storage medium associated with routing data in a switch are provided. In embodiments, the switch may include route lookup circuitry determine a first set of output ports that are available to send a data packet to a destination node. The lookup circuitry may further select, based on respective congestion levels associated with the first set of output ports, a plurality of output ports for a second set of output ports from the first set of output ports. An input queue of the switch may buffer the data packet and route information associated with the second set of output ports. The switch may further include route selection circuitry to select a destination output port from the second set of output ports, based on updated congestion levels associated with the output ports of the second set of output ports. Other embodiments may be described and/or claimed.
