ABSTRACT:
First, second and third communication control apparatus are arranged in a logic ring, with management information, such as address information, being transmitted in a data packet transmitted around the ring. When the received packet data includes management information of the apparatus that has just received it, that information is deleted. On the other hand, when the received packet data does not include management information of the receiving apparatus, management information of the receiving apparatus is added to the packet data. In this way, the management information can be updated for all the apparatus in a simple fashion and in a short amount of time.
