Polling response selection using request monitoring in a network switch apparatus

摘要

A switch node includes arbiter logic configured to gather global information regarding switching requests within the switch node and to control switching of one or more packets through the switch node. The arbiter logic may include a bus snooping interface configured to detect the switching requests within the switch node. The bus snooping interface includes a plurality of switching request destination registers configured to store switching request destination information from the detected switching requests. In addition, the arbiter logic includes a packet switching request array configured to transmit a next switching request within the switch node according to prior switching request destination information stored in the switching request destination registers. The switching of the one or more packets may be through a cross-point switch matrix in the switch node.
