Abstract

In a network management operation system connected via a communication line to a network having a plurality of object instances to be managed, the management information database stores management information of the containment relationship between object instances in the form of table. When an operator designates some object instances and enters a control command for the designated object instances, the management information of the designated object instances is retrieved from the management information database and a containment tree (management information having a containment structure) corresponding to the containment relationship between the designated object instances is generated, respectively within the network management operation system. In accordance with the generated containment tree, a scope pattern of Common Management Information Service (CMIS) of Open Systems Interconnection (OSI) is automatically generated.

Claims

1. A network management operation system connected to a network via a communication line, the network having a plurality of object instances to be managed, said network management operation system, comprising:

a plurality of input/output processing units each having input means and a display screen to be operated by an operator;

a management information database for storing management information including a containment relationship between plurality of object instances of said network to be managed and data of each of said object instances; and

a network management unit connected to said plurality of input/output processing units and said management information data base, said network management unit including;

means for generating a new integrated control command from a control command group for object instances having a same attribute independently inputted by a plurality of operators from said plurality of input/output processing units;

means for retrieving said management information of an object instance group in said network designated for said integrated control command, from said management information database, and generating a containment tree (management information having a containment structure) corresponding to the containment relationship between the object instances of said designated object instance group;

means responsive to said integrated control command for determining a scope pattern of Common Management Information Service (CMIS) of Open Systems Interconnection (OSI) in accordance with said containment tree;

means for generating a service message including said determined scope pattern, and transmitting said service message via said communication line to said network; and

means for distributing execution results of said service message from said network to each of said input/output processing units in accordance with said object instance group inputted by said plurality of operators.

2. A network management operation system according to claim 1, wherein said network management unit includes:

means for judging whether an occurrence frequency of control commands of said control command group entered by said plurality of operators from said plurality of input/output processing units exceeds a predetermined threshold value; and

means for inhibiting an integration operation by said means for generating said new integrated control command if said means for judging judges that the occurrence frequency does not exceed said threshold value.

3. A network management operation system according to claim 1, wherein said management information database further stores attribute information for each of said plurality of object instances within the network,

said scope pattern determining means being responsive to a designation of said attribute information by said operator, and determines a filter parameter for selecting an object instance, said filter parameter being determined by a scope parameter determined by said designated control command, and by said designated attribute information, and

said means for generating a service message generates a service message including said determined scope parameter and filter parameter, and transmits said service message via said communication line to said network.

4. A network management operation method for a network management operation method connected to a network via a communication line, the network having a plurality of object instances to be managed, said network management operation system, comprising:

a plurality of input/output processing units each having input means and a display screen to be operated by an operator;

a management information database for storing management information including the containment relationship between a plurality of object instances of said network to be managed and data of each said object instance; and

a network management unit connected to said plurality of input/output processing units and said management information data base, said network management unit executing the following steps;

(a) generating a new integrated control command from a control command group for object instances having the same attribute independently inputted by a plurality of operators operating said plurality of input/output processing units;

(b) retrieving said management information of an object instance group in said network designated for said integrated control command, from said management information database, and generating a containment tree (management information having a containment structure) corresponding to a containment relationship between the object instances of said designated object instance group;

(c) in response to said integrated control command, determining a scope pattern of Common Management Information Service (CMIS) of Open Systems Interconnection (OSI) in accordance with said containment tree;

(d) generating a service message including said determined scope pattern, and transmitting said service message via said communication line to said network; and

(e) distributing execution results of said service message from said network to each of said input/output processing units in accordance with said object instance group inputted by said plurality of operators.

5. A network management operation method according to claim 4, wherein said network management unit further executing the following steps of:

(f) judging whether an occurrence frequency of control commands of said control command group entered by said plurality of operators from said plurality of input/output processing units exceeds a predetermined threshold value; and

(g) inhibiting an integration operation if a result of said judging indicates that the occurrence frequency does not exceed said threshold value.

6. A network management operation method according to claim 4, wherein said management information database further includes storing attribute information for each of said plurality of object instances within the network, and wherein

in step (c), in response to a designation of said attribute information by said operator, determining a filter parameter for selecting an object instance, said filter parameter being determined by a scope parameter determined by said designated control command, and by said designated attribute information, and

in step (d), a service message including said determined scope parameter and filter parameter is determined and transmitted via said communication line to said network.
