摘要： A system for controlling topology views for operators in network management includes a data-storage unit which stores data of a base topology view, a security-management unit which controls access-authorization information with respect to each of the operators, the access-authorization information for a given operator defining network elements accessible by the given operator, and a topology-view-management unit which generates data of a dependent topology view by making a partial copy of the data of the base topology view only with respect to the network elements accessible by the given operator, thereby providing the dependent topology view to be presented to the given operator.

摘要： The present invention relates to a method of rerouting a PVC route on an ATM network by previously defining an alternate route for the PVC route and by switching the PVC route to a previously defined alternate route when a fault occurs in a network element forming the PVC route. Further, the present invention relates to a network management system connected to a plurality of network elements, and includes an ATM network resource managing unit for managing resources included in the ATM network; a PVC connection managing unit connected to the element data collecting unit through the LAN or WAN for managing situation of connection of the PVC route; a PVC route searching unit for searching the PVC route; a fault event analyzing unit for receiving a fault from the fault notifying unit through the communication network when the fault occurs at any one of network elements, and analyzing the fault; an alternate route defining unit for previously defining the alternate route for the PVC; and an alternate route processing unit for switching a faulty route to the alternate route defined by the alternate route defining unit when the fault occurs at any one of network elements.
摘要翻译：本发明涉及一种在ATM网络上重新路由PVC路由的方法，通过预先为PVC路由定义备用路由，并且在形成PVC路由的网络元件中发生故障时将PVC路由切换到先前定义的备用路由。此外，本发明涉及连接到多个网络元件的网络管理系统，并且包括用于管理包括在ATM网络中的资源的ATM网络资源管理单元; PVC连接管理单元，通过LAN或WAN连接到元件数据收集单元，用于管理PVC路由的连接状态; PVC路由搜索单元，用于搜索PVC路由; 故障事件分析单元，当故障发生在任何一个网络元件时，通过通信网络从故障通知单元接收故障，并分析故障; 用于先前定义PVC的替代路由的备用路由定义单元; 以及备用路由处理单元，用于当故障发生在任何一个网络元件时，将故障路由切换到由备用路由定义单元定义的备用路由。

摘要： A network management device for managing a plurality of network elements has a network element management data acquisition unit for acquiring, in stages, various management data possessed by the network elements when a session with a network element is resumed and when the network management device itself is started up, a rule management table for storing a dependence relationship between an operation and management data necessary to execute the operation, a feasible operation decision processing unit which, when an operation has been specified, refers to the dependence relationship to determine whether management data necessary to execute the operation has been acquired. If the necessary management data has been acquired, a network management execution unit executes network management conforming to the operation.
