Abstract
A CPU executes a process including determining a core node among plural relay nodes on a basis of route information, acquiring a first and a second packets flowing between a server and a terminal apparatus, the second packet being transmitted on a basis of the first packet, calculating a first delay time on a basis of the first and the second packets, the first delay time relating to packet transmission between the server and the terminal apparatus, transmitting a third packet to the core node, receiving a response to the third packet from the core node, calculating a second delay time on a basis of the third packet and the response, the second delay time being a delay time of the core node, and calculating a third delay time being a delay time of an end node on a basis of the first and the second delay times.
