METHOD AND SYSTEM FOR MAINTAINING/MANAGING NETWORK

摘要

PROBLEM TO BE SOLVED: To provide a method and a system for maintaining/managing a network in which a trouble alarm can be monitored accurately during actual maintenance work. SOLUTION: A trouble alarm being generated from each unit 106, 107, 108 constituting a network during maintenance work is determined by simulation 110. An alarm comparator 111 compares a trouble alarm generated during actual maintenance work with a trouble alarm determined by simulation 110 thus distinguishing an actually occurred trouble alarm.
