Abstract
Each chip arranged in each crossbar switch creates and issues, if a packet is input, a log collection packet for collecting a log of the packet. Each chip collects a log related to a transfer of the input packet. Each chip embeds, in the issued log collection packet or a log collection packet transferred from a crossbar switch in a previous stage, the collected log. If a transfer destination of the packet is other than the crossbar switches, each chip stores, in a storage space, the log embedded in the log collection packet and then transfers, to the transfer destination, only an original packet in which the log is deleted. In contrast, if the transfer destination is a crossbar switch, each chip transfers the log collection packet to a crossbar switch in a next stage.
