System and method to enable fairness on multi-level arbitrations for switch architectures

A switch comprising:

• a first flow counter circuitry associated with a first input port, the first flow counter circuitry to count input streams flowing through the first input port to generate input stream counts;
• a weighted arbiter circuitry to pass input streams from the first input port to an output port, wherein fairness is to be calculated based on a weight derived from the count of input streams from first flow counter circuitry.

A system for switch arbitration, comprising:

• a subswitch of a plurality of subswitches, the subswitch coupled to a plurality of input ports and an output port;
• an input port of the plurality of input ports coupled to an associated flow counter, the associated flow counter to increment when an input flows through the input port;
• a first weighted arbiter switch coupled to the plurality of subswitches, the first weighted arbiter to receive a weight value from the subswitch, the weight value of the subswitch being dependent on at least one flow counter value associated with the subswitch, the first weighted arbiter to receive an additional weight value from an additional subswitch, the additional weight value of the additional subswitch being dependent on at least one flow counter value associated with the additional subswitch, wherein the first weighted arbiter switch enables flow from the plurality of input ports to the output port based on the respective weights for the subswitch and additional subswitch.
