In such a management method, the tenants are divided in units of the network nodes 3 to 7, so that one network node cannot be shared by a plurality of tenants. Can not. That is, it is not possible to manage one network node into tenants in units of a plurality of packages 31 to 40 mounted in the network node. For example, the packages 33 and 34 of the network node 4 can be used only for the tenant A and cannot be used for the tenant B.

Also, a plurality of NSPs 8 and 9 equipped with a network management system are required for each tenant. INDUSTRIAL APPLICABILITY According to the present invention, in a network management system in which one network system is used by a plurality of tenants, it is possible to perform management by dividing tenants by a package in a network node, and clarify the demarcation of responsibility such as network management and monitoring. Another object of the present invention is to provide a network management system capable of properly operating a network system.

In the illustrated example, a part of the package 33 of the network node 4 and the network nodes 3, 6 and 7 form an asset of the tenant A, and a part of the package 34 of the network node 5 and the network node 4 forms the asset of the tenant B. Is forming.

The NSP 11 having the network management system common to the tenants A and B is connected to the common network node 4. FIG. 1 shows the details of the integrated network management system. The network management system 12 mounted on the NSP 11 is connected to the network node 4. In the network node 4,
A supervisor 43 is provided. Supervisor 43
Is a management interface, which transfers change information, accident information, and the like to the network management system 12 when the configuration of the network system is changed or an accident occurs.

A package for connecting a terminal is installed in the slot of the network node 4. In the example of FIG. 1, the package 33 for tenant A and the package 34 for tenant B are mounted on the network node 4. The network management system 12 includes an interface 21, a CPU 22, a common network definition data file 23, and network definition data 2 for each tenant.
4, 25, and network management programs 26, 27 for each tenant. In the illustrated example, the number of tenants is two, but this number can be any number of two or more. Further, the monitor 13 and the input device 14 common to the tenant A and the tenant B are connected to the network management system 12.

The CPU 22 controls the entire network management system 12. The common network definition data file 23 stores network definition data in units of packages of the network nodes 3 to 7 that are managed by the network system. The definition data stored in the common network definition data file 23 is composed of configuration information, failure information, performance information and the like. This information is sent to the supervisor 43 of the network node 4.
It is rewritten by the data transferred from.

In the network definition data files 24 and 25 for each tenant, of the network definition data,
Network definition data belonging to each tenant is stored. When the data in the common network definition data file 23 is changed, the data in the corresponding tenant network definition data files 24 and 25 are rewritten, and the common network definition data file 23 and the tenant network definition data files 24 and 25 are rewritten. And are always synchronized.

Network management programs 26, 27
Displays the configuration information, failure information, and performance information of the network system on the monitor 13 by accessing the user (administrator) for each tenant, or notifies the user when a failure occurs in the network system.
