摘要： PROBLEM TO BE SOLVED: To provide a distribution management network system, capable of suppressing the deviation of a data amount managed by a node.SOLUTION: A bootstrap node Pb overwrites a portion of the top of the node ID with a uniquely allocated fixed-length prefix.

The bit length of the prefix of the non-bootstrap node Pn is defined shorter as there comes to be a longer distance between a position of the bootstrap node Pb, located nearest to the non-bootstrap node Pn in the network, mapped on a virtual circumference and a position of the bootstrap node Pb mapped to sandwich the non-bootstrap node Pn on the virtual circumference with the bootstrap node Pb.
