Abstract

PURPOSE:To prepare a network management application rich in extensionality and flexibility by providing a network resource managing means to manage information such as the attribute, etc., of a managing object in an integrated network management system(INMS) and a sub network management system (SNMS). CONSTITUTION:An INMS 1 and an SNMS 4 are connected by an OSI protocol. A management application 11 accesses an object retrieval service application 14 and an network resource management mechanism (NRM) kernel 13 as the element of an NRM. The management application 11 requires information concerning a managing object 2. In the other case, an NRM server 19 or 41 to be accessed is specified as well and an NRM cliant 15 accesses the NRM server by the system managing function of an OSI. The NRI server 19 and 41 manage the dynamic information of managing objects 21 and 22. Thus, the management application with high general usefulness can be prepared to be flexible to the extension and change, etc., of a network.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a network management method for an integrated network in which sub-networks composed of one or several types of network devices are intricately intertwined as a whole. Regarding.

[Conventional technology]

In this type of integrated network management, network management is generally performed by providing multiple subnetwork management systems (SNMS) that manage subnetworks and an integrated network management system (INMS) that integrates and manages these multiple SNMS. It is true. In traditional network management methods, devices defined by modeling.

When checking management targets such as circuits from INMS, I
In the application (program) in the NMS, it is necessary to consider all information such as the route to the subnetwork to which the managed target belongs, the type of the subnetwork concerned, and the type of the managed target.

[Problem to be solved by the invention]

In the conventional integrated network management method mentioned above,
In the INMS network management application, it was necessary to create a separate application that takes into consideration the attributes of the managed object. For this reason, applications have to be re-created every time the network is expanded or changed, and this also causes an increase in the processing amount of the INMS.

[Means to solve the problem]

An object of the present invention is to provide an integrated network management method that allows creation of highly expandable and flexible network management applications in an integrated network composed of a plurality of subnetworks. For this reason, the present invention provides network resource management (NRM) for managing information such as attributes of managed objects in INMS and SNMS.
Setting the means and achieving the goal.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing the functional configuration of an integrated network management system (INMS) 1 and a subnetwork management system (SNMS) 4 used in the integrated network management method of the present invention.

In this embodiment, a case where there is one SNMS 4 is shown for simplicity of explanation. INMSI and SNMS4 are O3I
Connected by flotcol.

In addition, the managed object 2 in network management is abstracted (encapsulated) by object-oriented modeling,
Furthermore, the first management target 21 managed by INMSI and S
It is distributed to the second management target 22 managed by the NMS 4. The management application 11 is written in an object-oriented language such as Cf1h using abstracted management objects and the contents of their management. That is, in the management application 11, there is no need to consider the route, attributes, etc. to the managed object. The management application 11 uses an object search service application (OR8) 1 via a high-level language interface (HLLIF) 12.
4 and the NRM Kernel 13, which is an element of the Network Resource Management Mechanism (NRM). The OR314 directly accesses the database 16 from the management application 1■.
When a search request is made, the corresponding information is searched from the database 16 and returned to the management application 11.

On the other hand, when the management application 11 requests information about the managed object 2, the NRM kernel 13 follows the request, that is, the object, and determines whether the object is data existing in the database 16 or information about the managed object 21 in the INMSI. If the data exists in the database 16, it is searched and the result is returned to the management application 17. On the other hand, in other cases, the NRM server 19 or 41 to be accessed is also specified, the database 16 is searched as necessary, and the data is passed along with the search data to the controlling NRM client 15. The NRM client 15 uses the system management function (manager function) of the O8I to access the NRM server to be accessed by first and second SI network management protocol entities (SI-NMPE) 17.
and 18, or the first and third O8I-NMPEs
Access via l7 and 42.

The first and second NRM servers 19 and 41 manage dynamic information (information that changes depending on the network status, such as line and route information) of the corresponding managed targets 21 and 22, and the system management function (agent function)
have. NRM server is the corresponding O3I-NMP
Execute the request from the NRM client 15 given via E, and send the information to be managed to the NRM client 15.
Return to.

Thus, NRM kernel 13. By providing an NRM consisting of an NRM client 15 and an NRM server 19 or 41, the management application 11 does not need to consider the attributes, routes, etc. of each managed object, and is a general-purpose system that is flexible and adaptable to network expansion and changes. This makes it possible to create highly flexible management applications.

〔Effect of the invention〕

As explained above, according to the integrated network management method of the present invention, an application does not need to be aware of where the managed target is managed, and even if the managed target is based on different modeling, the same INMS model can be used. can be managed.

Furthermore, only applications are manufactured for each system,
This has the effect of allowing the NRM portion to be used in other management systems.
