摘要： A clustered network may include a plurality of switch boxes where a master switch box may communicate and control hardware devices in remote switch boxes. The switch boxes in the network may each include a multiplexer, for example, a field programmable array (FPGA) that may process message requests related to hardware devices of a switch box. If the hardware device is in a remote switch box, then the FPGA of the master switch box may process the status data from the remote switch box so that a local processor in the master switch box can read the status data.
