System and method for port arbitration in a switch network for dataflow computing systems, particularly in computer systems having a plurality reconfigurable processing units interconnected using switches. A switch network comprises a switch, a plurality of nodes coupled to the switch, and a Dynamic Equality of Service (DEoS) arbiter. The DEoS arbiter may perform operations to arbitrate among input ports of the switch to make a through-connection. Based on the port DEoS metrics, the arbiter selects an input port of the switch to make a through-connection to an output port of the switch. DEoS metrics may include DES counters, and/or quantization ranges of DEoS counters, associated with the source nodes.
A switching apparatus of a computing system, the switching apparatus comprising:
A computer-implemented method for arbitrating among input ports in a switch having a plurality of input ports for allocating through-connections to an output port, the method comprising:
The computer-implemented method 18, wherein the DEoS arbiter uses a round robin pointer (RRP) to indicate a particular input port currently using, last using, or next to use a through-connection to an output port;
