A first communication apparatus receives, from a second communication apparatus, information indicating the number of relays from a first supplying apparatus to the second communication apparatus. The first communication apparatus receives, from a third communication apparatus, information indicating the number of relays from a second supplying apparatus to the third communication apparatus. The first communication apparatus transmits, to the third communication apparatus, information indicating the number of relays from the first supplying apparatus to the first communication apparatus. The first communication apparatus transmits, to the second communication apparatus, information indicating the number of relays from the second supplying apparatus to the first communication apparatus. The first communication apparatus selects the second communication apparatus, which has a smaller number of relays among the second and the third communication apparatuses. The first communication apparatus synchronizes a clock thereof with a clock of the second communication apparatus.
A communication apparatus that selects any one clock from among clocks supplied through a plurality of paths from supplying apparatuses of a master clock and that synchronizes a clock of the communication apparatus with the clock selected, the communication apparatus comprising:
