摘要

A connection uploading unit (405) uploads path information about a PVC established in a network from each NE (101) at a desired time point, and reflects the uploaded path information as the data of an NMS (201). A connection diagnosing unit (406) detects an inconsistency between the PVC data stored in the network and that stored in the NMS (201). A connection re-establishing unit (407) provides the path information for correcting the contents of the inconsistency to the NMS (201) itself or each NE (101), and re-establishes the PVC, when the inconsistency is detected.
