COMMUNICATION SYSTEM AND METHOD
First Claim
1. A communication system comprising:
- a first node including a first memory and a first processor coupled to the first memory; and
a second node including a second memory and a second processor coupled to the second memory, whereinthe first processor is configured to;
obtain first information indicating reachability of data to the second node in a case of transmitting the data to the second node;
specify a number of frames in a case of transmitting, to the second node, a file to be used for updating of software at the second node;
specify, based on the first information and the number of frames, a transmission method candidate to transmit the file from the first node to the second node; and
notify the second node of the specified transmission method candidate,the second processor is configured to;
generate updating information indicating whether the software can be updated based on the file to be transmitted by the transmission method candidate; and
notify the first node of the updating information, the first processor is configured to;
specify a transmission method of the file from the transmission method candidate, based on the updating information; and
transmit the file to the second node by using the specified transmission method, andthe second processor is configured to execute the updating of the software by using the file transmitted from the first node.

10. A method executed by a first node and a second node, the method comprising:
-
obtaining, by the first node, first information indicating reachability of data to the second node in a case of transmitting the data to the second node; specifying, by the first node, a number of frames in a case of transmitting, to the second node, a file to be used for updating of software at the second node; specifying, by the first node, based on the first information and the number of frames, a transmission method candidate to transmit the file from the first node to the second node; notifying, by the first node, the second node of the specified transmission method candidate; generating, by the second node, updating information indicating whether the software can be updated based on the file to be transmitted by the transmission method candidate; notifying, by the second node, the first node of the updating information; specifying, by the first node, a transmission method of the file from the transmission method candidate, based on the updating information; and transmitting, by the first node, the file to the second node by using the specified transmission method; and executing, by the second node, the updating of the software by using the file transmitted from the first node. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
