ABSTRACT:
A plurality of nodes are connected to one another so as to form a ring network. A pseudo master node blocks relay of user data on one side, and transmits in the ring network a health packet that contains information about a priority order in which the pseudo master node is to be set as a master node. If the pseudo master node receives the health packet transmitted by it, or receives a health packet transmitted by another node, the pseudo master node judges whether the pseudo master node is to be set as a master node based on the priority order contained in the received health packet.
