<P>PROBLEM TO BE SOLVED: To provide a network time synchronizing method in which a tree form seen from a root is considered to shorten a synchronizing focusing time. <P>SOLUTION: The network time synchronizing method includes a step of synchronizing the clock of a slave with the synchronizing clock of a master in which the function of a communication unit of opposed one node is the master and the function of the communication unit of the other node is as the slave, and a step of synchronizing the clock of the master with the clock of the slave in the node that the master and the slaver are contained. The network time synchronizing method further includes a first step of acquiring the number of subordinate clock synchronizing under the master and the slave by the master and the slave, and a second step of synchronizing the clock of the master with the clock of the slave having the maximum number of the subordinate clock for the node containing the master and the slave. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
