COMMUNICATION SYSTEM, COMMUNICATION METHOD, AND COMMUNICATION PROGRAM

Document Type and Number:

WIPO Patent Application WO/2016/002367

Kind Code:

A1

Abstract:

The present invention addresses the problem of reducing the influence of fluctuations in the delay of a synchronization packet by a simple configuration when a network is configured using a relay device. To solve this problem, the present invention is characterized by comprising: processing in which a first communication control device gives first time information relating to a time when a synchronization packet has been received or a time when the received synchronization packet is transmitted to a relay device to a packet to be transmitted to the relay device; processing in which a second communication control device obtains information relating to communication delay between the first and the second communication control device of the synchronization packet from second time information relating to a time when the synchronization packet transmitted via the relay device has been received or a time when the received synchronization packet is transmitted to another communication device, and the first time information; and processing in which the obtained information relating to the communication delay is given to a packet to be transmitted to the other communication device.
