<P>PROBLEM TO BE SOLVED: To reduce the load on user traffic by identifying a fault section effectively and reducing an unnecessary fault notification. <P>SOLUTION: A terminal device which can terminate OAM signals such as a CCM frame is installed at a user's site so as to enable normality monitoring between sites of End-End and a control unit which controls the termination device is installed in a VLAN network used by the user. The remote control of the termination device is performed from a controller, and the table information which the controller holds is collectively managed by being led by an operator, and the information of the termination device under connection is notified to the operator based on the outcomes of MAC learning performed by the controller, and the ID managed by an undertaker is designated to the connectivity monitoring section by the operator, so as to enable connectivity monitoring per section unit. <P>COPYRIGHT: (C)2013,JPO&INPIT |
