Communication Control Device and Communication Quality Measurement Method

A communication quality measurement method for use in a communication control device that includes a first processor, a first memory connected to the first processor, and a first network interface connected to the first processor, and connects a first network to a second network, the first network being connected to a delivery server that includes a second processor, a second memory connected to the second processor, and a second network interface connected to the second processor, and delivers data packets containing plural pieces of content, the second network being connected to a plurality of computers that each include a third processor, a third memory connected to the third processor, and a third network interface connected to the third processor, and acquire the data packets from the delivery server, the method comprising the steps of:

• causing the communication control device to acquire control information, which is to be transmitted to the delivery server in order to let the computers acquire the data packets from the delivery server;
• causing the communication control device to extract computer identification information, which identifies the computers targeted for measuring the delivery quality of the data packets to be transmitted, and data packet identification information, which identifies the data packets to be measured and transmitted to the identified computers, from the acquired control information;
• and
• causing the communication control device to measure the delivery quality of the data packets targeted for measurement, which are to be transmitted to the identified computers, in accordance with the extracted computer identification information and the extracted data packet identification information.
