Abstract
A communication system that is constituted by a plurality of communication apparatuses, and performs time synchronization using a time synchronization frame, wherein one of the communication apparatuses is set as a starting point node, at least one of the communication apparatuses is set as a terminal point node, the starting point node generates a time synchronization frame in an outward-route direction and transmits the generated time synchronization frame in the outward-route direction, the terminal point node generates a time synchronization frame in a return-route direction and transmits the generated time synchronization frame in the return-route direction, and an intermediate node relays a received time synchronization frame when receiving a time synchronization frame transmitted in an outward-route direction and a return-route direction.
