INFORMATION PROCESSING DEVICE THAT GENERATES PACKET INCLUDING FIRST AND SECOND IDENTIFIERS, TRANSMISSION AND RECEPTION DEVICE, AND CONTROL METHOD OF INFORMATION PROCESSING DEVICE

摘要

A first communication device included in an information processing device stores, for each first identifier that is allocated for identifying a first packet, situation information indicating a second identifier that is allocated along with the first identifier, and updates the situation information on the basis of a reception result of a second packet indicating an execution result of processing that is requested by the first packet. Then, the first communication device determines the first identifier and the second identifier that are allocated to the first packet on the basis of the situation information and generates and transmits the first packet storing the first identifier and the second identifier that. A second communication device included in the information processing device transmits the second packet after storing the second identifier stored by the first packet in the second packet when transmitting the second packet as a response to the first packet.

主权项

1. An information processing device comprising:
an arithmetic operation processing device; a plurality of input/output devices; and a plurality of communication devices configured to perform communication between the arithmetic operation processing device and the plurality of input/output devices, wherein a first communication device that belongs to the plurality of communication devices and that transmits a first packet includes:
a storage circuit configured to store, for each first identifier that is allocated for identifying the first packet, situation information indicating a second identifier that is allocated along with the first identifier;a reception circuit configured to receive a packet that is addressed to the first communication device;an updating circuit configured to update the situation information stored in the storage circuit on the basis of a reception result by the reception circuit of a second packet indicating an execution result of processing that has been requested by the first packet;a determination circuit configured to determine the first identifier and the second identifier that are allocated to the first packet on the basis of the situation information stored in the storage circuit; anda first transmission circuit configured to generate and transmit the first packet storing the first identifier and the second identifier that have been determined by the determination circuit, and a second communication device that belongs to the plurality of communication devices and that is a transmission destination of the first packet includes a second transmission circuit configured to transmit the second packet after storing the second identifier stored by the first packet in the second packet when transmitting the second packet as a response to the first packet that has been transmitted by the first communication device.
