NETWORK SYSTEM, NODE DEVICE, AND METHOD OF CONTROLLING NETWORK SYSTEM

摘要

A node device which is provided in a network and for transmitting a packet including a first header portion, a second header portion, a payload data portion, the node device includes: a memory and a processor coupled to the memory. The processor is configured to: calculate a first value that is a first logical relationship for payload data set in the payload data portion and first header information including a transmission destination address set in the first header portion, and transmit a packet including the payload data, the first header information, second header information including a final transmission destination address set in the second header portion, the first value and a second value that is a second logical relationship to the payload data and the second header information to outside of the node device.

主权项

1. A network system which includes a plurality of node devices and in which a packet including a first header portion, a second header potion, and a payload data portion is transferred, the network system comprising:
a first node device that is one of the plurality of nodes device and includes a first processor; and a second node device that is one of the plurality of node devices and includes a second processor, wherein the first processor is configured to:
calculate a first value that is a first logical relationship for payload data set in the payload data portion and first header information including a transmission destination address set in the first header portion, andtransmit a packet including the payload data, the first header information, second header information including a final transmission destination address set in the second header portion, the first value, and a second value that is a second logical relationship to the payload data and the second header information to outside of the first node device, the second processor is configured to perform, when a value that is to be the first logical relationship to information stored in the payload data portion in the packet received from outside of the second node device and information stored in the first header portion does not match the first value and a value that is the second logical relationship to information stored in the payload data portion in the received packet and information stored in the second header portion matches the second value, control that causes transmission of a packet based on the received packet to a third node device that is one of the plurality of node devices.
