摘要：One or more nodes on a communication network are selected and set as onenode group. In each of the nodes, group identification information representing the nodegroup to which the node belongs is stored in advance. The group identification
information is attached to the header of a data packet to be transmitted, so that nodesconstituting a node group that should commonly receive data can be readily identified bycomparing the group identification information imparted to the transmitted data packetand the group identification information stored in each receiving node. Given node canchoose to become a node of a particular function, such as a clock master node, in whichcase control is performed to delete, from the node group, a node having so far playedthe role of the node of the particular function in such a manner that there exists only onenode of the particular function per node group.
