Abstract

Operation of a network which comprises a plurality of mutually connected subordinate-networks is performed. Operation information is unitarily managed transmitted and received in the entirety of the network. An information storing unit stores operation management information used for the network operation management. A communications unit transmits and receives the operation information. Control is performed so that when the operation information is received from a subordinate-network, updating processing is performed if the contents of the operation information should be affected in the operation management information, and, operation information for reporting is produced and distributed to needing subordinate-networks based on the operation management information if reporting processing should be performed.

Claims

1. A network operation managing system, for operation of a network which comprises a plurality of mutually connected subordinate-networks, said system being connected with the whole network and operation information transmitted from said whole network being unitarily managed by said system, said system comprising:

information storing means for storing operation management information used for the network operation management; and

communication means for transmitting and receiving the operation information;

wherein control is performed so that when the operation information is transmitted from a subordinate-network, updating processing is performed when the contents of said operation information is determined to be reflected in said operation management information, and, operation information for reporting is produced and distributed to necessary subordinate-networks based on said operation management information when reporting processing is performed.

2. The network operation managing system according to claim 1, further comprising problem monitoring means for monitoring problem occurrence in said network;

wherein control is performed so that said operation management information includes problem diagnosis information used as problem diagnosis reference; and

a problem being diagnosed based on said problem diagnosis information when said problem monitoring means detects said problem, the operation information for reporting information concerning said problem is produced based on a result of the diagnosis and said operation management information and is distributed to necessary subordinate-networks, and updating processing is performed on said operation management information when a result of said problem is affected in said operation management information.

3. The network operation managing system according to claim 1, wherein:

said operation management information includes target extent information for defining a network extent on which the operation management is performed; and

contents of said operation management information are determined and managed wherein said network extent defined by said target extent information is treated as a target of the operation management.

4. The network operation managing system according to claim 1, wherein said operation management information is configured such that a plurality of information units for respective items of the network operation management are independent of each other.

5. The network operation management system according to claim 1, wherein:

said operation management information includes reporting scope information which defines a correspondence relationship between sending origins and reporting destinations of the operation information transmitted and received in said network; and

when reporting processing is performed for the currently received operation information, a reporting destination is determined depending on the sending origin of said operation information based on said reporting scope information, the operation information for reporting being then transmitted to said reporting destination.

6. The network operation managing system according to claim 5, wherein;

said reporting scope information further defines a corresponding relationship between problem occurrence locations and reporting destinations in said network; and

when reporting processing relating to occurrence of a problem is performed, a reporting destination is determined depending on location of said problem based on said reporting scope information, the operation information for reporting being then transmitted to said reporting destination.

7. The network operation managing system according to claim 5, wherein each correspondence relationship defined by said reporting scope information can be altered in response to a receiving an alteration request from a respective sending origin or a respective reporting destination.

8. The network operation managing system according to claim 1, wherein:

said information storing means records sending order information of the operation information which updates an information unit when said information unit of said operation management information is updated; and

when updating processing is performed on said operation management information in response to received operation information, the sending order information of said received operation information is compared with the sending order information recorded for the information unit to be updated, whether updating of said information unit can be performed being determined based on a result of the comparison.

9. The network operation managing system according to claim 1, wherein:

said operation management information includes access level information which defines accessing allowance levels for information classifications and information request origins; and

when accessing which request information is accepted, information disclosure is controlled according to the access allowance level defined for the information classification of the requested information and the requesting origin based on said access level information.

10. A computer-implemented network operation managing method, for operation of a network which comprises a plurality of mutually connected subordinate-networks, said system being connected with the whole network and operation information transmitted from said whole network being unitarily managed by said system, said method comprising steps of:

a) storing operation management information used for the network operation management;

b) transmitting and receiving the operation information; and

c) performing a control so that when the operation information is transmitted from a subordinate-network, updating processing is performed when the contents of said operation information is determined to be reflected in said operation management information, and, operation information for reporting is produced and distributed to necessary subordinate-networks based on said operation management information when reporting processing is performed.

11. A computer program product, for operation of a network which comprises a plurality of mutually connected subordinate-networks, said system being connected with the whole network and operation information transmitted from said whole network being unitarily managed by said system, said product comprising a computer usable medium having computer readable program code means embodied in said medium, said computer readable program code means comprising:

program code means for storing operation management information used for the network operation management;

program code means for transmitting and receiving the operation information; and

program code means for performing control so that when the operation information is transmitted from a subordinate-network, updating processing is performed when the contents of said operation information is determined to be reflected in said operation management information, and, operation information for reporting is produced and distributed to necessary subordinate-networks based on said operation management information when reporting processing is performed.
