Abstract:
Provided are a PCIe switch provided with a bandwidth control function, and a computer system using the same. The PCIe switch has: input ports to which are connected initiators that generate packets; output ports to which are connected targets that are the transmission destinations of the packets; and an output port adjustment section intervening between the input ports and the output ports, for adjusting the output of packets from the input ports to the output ports. The input ports further have a bandwidth control section that establishes bandwidth limit values beforehand for each of a plurality of divided groups; classifies packets transmitted from the initiators into any of the plurality of groups according to a predetermined rule; and outputs the classified packets to the output port adjustment section, on the basis of the bandwidth limit values.
