<p><P>PROBLEM TO BE SOLVED: To provide a network system for solving the problem that the congestion of user data can not be accurately detected. <P>SOLUTION: The generation part of the network node 1 generates congestion state confirmation signals, and the transmission part of the network node 1 transmits the congestion state confirmation signals generated by the generation part as user data. When the reception part of the network node 3 receives the congestion state confirmation signals, the control part of the network node 3 determines whether the congestion of the user data occurs on the passing route of the user data on the basis of the congestion state confirmation signals received by the reception part. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
