Abstract
A packet switch including input ports and output ports allocates an output bandwidth of each output port among virtual channels based on bandwidth allocations values corresponding to the virtual channels and a bandwidth precision value of the output port. The bandwidth precision value indicates a number of bandwidth precision bits, which may be outside a bandwidth reservation precision range specified in a serial RapidIO standard. The packet switch receives data packets compliant with the serial RapidIO standard at the input ports, identifies an output port for each data packet, and selects input ports based on the output ports of the data packets. Further, the packet switch routes a data packet from each selected input port to the output port of the data packet, and the output port outputs the data packet by using the output bandwidth of the output port allocated to the virtual channel identified by the data packet.
