<p>According to the present invention, if an EMS110 needs to conduct control over a prescribed group of nodes 120 in the IP network 140 to exert a predetermined function, that is, to change the control mode, it creates, according to a control program, an active program AP which stores a control-subject address table and control contents of that group and then transfers it through a control network 150. At each node 120, if the active program executed by itself has normally ended, records this normal ending in the control-subject address table of the active program AP and also, based on this control-subject address table, transmits the active program to such a node 120 in the control-subject group that has not executed that program yet. If the active program AP has abended, on the other hand, it records this abending in the control-subject address table of the active program AP and also transmits the active program AP to the EMS110, thus suspending the control processing. <IMAGE></p> |
