The present invention relates to a management information conversion device that can be operated from a management device that performs management using another management protocol.

[0002]

2. Description of the Related Art There are various types of protocols for managing a group of information communication devices. Typically, CMIP (Common Management Information Protocol) is used as a management protocol for open system management (OSI management).
And SNMP as a management protocol for Internet management
(Simple Network Managemant Protocal) is known. If the management protocols are different, the contents of the management information of the managed devices managed by the management protocols are different from each other, and mutual connection cannot be easily made. Therefore, in addition to the protocol conversion of the management protocol, it is necessary to convert the management information.

Conventionally, in the case of OSI management and Internet management, instead of converting management information, the management information of a managed device of SNMP is defined in a management information format that can be understood by OSI management, and the Internet is understood. A method of cross-referencing by defining the management information of the managed device of CMIP in the form of management information that can be used has been adopted.

[0004]

In the case of the above method, the OS
When an SNMP managed device is to be managed by an I-managed network management device, it is necessary to add new management information to the network management device and change the management scenario or the like used by the application program on the management device. , When the management information about the managed device of SNMP increases, or when managing the managed device that uses a different management protocol, the definition and addition of new management information are always performed, and the management scenario used by the application program of the network management device, etc. There was a problem that it was necessary to change.

Next, the operation of this embodiment will be described with reference to the drawings.

First, a CMIP event is transmitted from the OSI network management device 1 by the CMIP protocol.
In the management information conversion device 10, the CMI event data received by the CMIP processing unit 11 is passed to the conversion rule processing unit 16 and the conversion process starts. FIG. 8 shows a flowchart of the conversion rule process. The event receiving unit 21 understands the content of the CMIP event data and determines the operation to be processed (event receiving 81). The MIB access means 22 performs operations such as reading and writing of data that becomes an event target in the MIB 13 (MIB access 82). When there is no information in the MIB 13 and conversion processing is necessary (conversion judgment 83), the rule interpretation means 23 is operated (rule interpretation 84). In the rule interpretation, the conversion rule file 15a is read and the processing content 31 of the conversion rule corresponding to the CMIP event is analyzed (rule content analysis 87). In the case of a CMIP get operation (managed device instance access judgment 88, MIB access judgment 90), according to the behavioral description 34 of the content of the conversion rule, the information of the managed device 2 is read and (managed access 8
9), by reading data on the MIB 13 (MIB
Access 91), data is acquired, and necessary data is repeatedly created according to the processing of the conversion rule. In the case of a CMIP set operation, it is necessary to write information on the managed device 2 (managed access 89) or write data on the MIB 13 (MIB access 91) according to the behavior description 35 in the conversion rule. The writing process is repeatedly performed. In the case of the CMIP action operation, necessary data is first created in the behavior description 37 according to the action description 33 in the conversion rule, and the application or the like in the action description 33 is repeatedly executed using the data as a parameter. The response information generation means 24 generates response information (response information generation 85) from the result of the MIB access means 22 or the result of the rule interpretation means 23 (rule interpretation end determination 92), and the CMIP event is sent to the CMIP processing unit 11. The response information that is the result of is sent (response information transmission 86). In the CMIP processing unit 11, the operation result is C
It is sent to the network management device 1 by MIP.

When the notification information from the SNMP managed device 2 is received, the SNMP processing unit 12 passes the notification information data to the notification information processing means 17, and the notification information conversion processing is performed. FIG. 9 shows a flowchart of the notification information processing means. The content of the notification information received from the SNMP processing unit 12 is passed to the notification information handling rule interpretation means 41 (notification information reception 101), the notification information handling rule 15b is read, and the contents of the notification information are understood (notification information rule. Content analysis 102). In order to specify the CMIP management target that is the source of the notification information, the CMIP that is the source of the notification from the address information or the like of the SNMP managed device 2 that is the source of the notification information according to the description of the notification information correspondence rule 15b.
The management target of is searched (management target search 103). CMI
The conversion into the P notification information is processed by the rule interpreting means 23 according to the notification conversion description 32 of the contents of the conversion rule 15a (rule interpretation 84). By this processing, necessary data is collected / created, the CMIP notification is generated from the data by the notification generation means 42 (notification information generation 104), and the CMIP notification is passed to the CMIP processing unit 11 by the notification issuing means 43 (notification information). Send 105). CMIP processing unit 11
Then, CMIP notification information is transmitted to the OSI network management device 1 using the CMIP protocol. The status change processing unit 18 monitors the status of the SNMP managed device 2. FIG. 10 shows a flowchart of the state changing process. When the management information converting apparatus 10 is started up, the managed device monitoring means 61 reads the monitoring rule 15c to search the managed device of the managed device 2 to be monitored and collect the information of the managed device 2 (monitoring rule). Interpretation 111), managed device 2
State management table 64 is created (state management table creation 11
2). When the managed device 2 uses the SNMP management protocol, the managed device monitoring means 61 uses the monitoring rule 15
The get operation is periodically performed on the management target of the managed device according to the interval of c (state monitoring of managed device 11
3). The state change is detected by comparing the result of the get operation with the value in the state management table (state change detection 114). When there is a state change, the CMIP management target is searched from the address information of the SNMP managed device that has changed the state in order to specify the management target issued by the state change notification (management target search 115). The CMIP notification information of the status change is generated from the retrieved management target. This is processed by the rule interpretation unit 23 according to the notification conversion description 32 of the contents of the conversion rule file 4 (rule interpretation 84), similarly to the notification generation unit 42 of the notification information processing unit 17. Necessary data is collected / created, and the notification generation means 62 generates a status change notification from the data (notification information generation 11
6), C is sent to the CMIP processing unit 11 by the notification issuing means 63.
The MIP notification is passed (notification information transmission 117). The CMIP processing unit 11 transmits the status change notification information to the OSI network management device 1 using the CMIP protocol.
After the notification is issued, the managed device monitoring unit 61 continues monitoring (managed device state monitoring 113).
