Abstract

A management device includes a storage unit and a processor. The processor is configured to store, when configuration information is updated by one client of a plurality of clients, the updated configuration information, generation information on a generation of the updated configuration information, and identification information of the one client in association with one another in the storage unit. The processor is configured to generate, when restoration to a first generation is requested by a first client, new configuration information with reference to information stored in the storage unit. The new configuration information does not include first contents of first updates made by the first client in second generations later than the first generation and includes second contents of second updates made in the second generations by second clients. The processor is configured to perform a configuration of a network device using the new configuration information.

Claims

1. A management device, comprising:

a storage unit; and

a processor configured to

store, when configuration information is updated by one client of a plurality of clients, the updated configuration information, generation information on a generation of the updated configuration information, and identification information of the one client in association with one another in the storage unit,

generate, when restoration to a first generation is requested by a first client of the plurality of clients, new configuration information with reference to information stored in the storage unit, the new configuration information not including first contents of first updates made by the first client in second generations later than the first generation and including second contents of second updates made in the second generations by second clients of the plurality of clients, the second clients being different from the first client, and

perform a configuration of a network device using the new configuration information.

2. The management device according to claim 1, wherein the processor is configured to

select, based on a comparison between a first number of the first updates and a second number of the second updates, whether to generate the new configuration information by reflecting the second contents in first configuration information corresponding to the first generation or by removing effects of the first contents from second configuration information corresponding to a latest generation.

3. The management device according to claim 1, wherein

the processor is configured to

distinguish between the first updates and the second updates on basis of the identification information and the generation information stored in the storage unit in association with corresponding configuration information.

4. The management device according to claim 1, wherein

the storage unit is configured to store therein restriction information on a restriction to be satisfied by configuration information of the network device, and

the processor is configured to

determine whether the new configuration information satisfies the restriction with reference to the restriction information stored in the storage unit,

perform the configuration of the network device using the new configuration information when the new configuration information satisfies the restriction, and

notify, when the new configuration information does not satisfy the restriction, the first client that the restoration to the first generation is not performed, without performing the configuration of the network device using the new configuration information.

5. A computer-readable recording medium having stored therein a program for causing a computer to execute a process, the process comprising:

storing, when configuration information is updated by one client of a plurality of clients, the updated configuration information, generation information on a generation of the updated configuration information, and identification information of the one client in association with one another in a storage unit;

generating, when restoration to a first generation is requested by a first client of the plurality of clients, new configuration information with reference to information stored in the storage unit, the new configuration information not including first contents of first updates made by the first client in second generations later than the first generation and including second contents of second updates made in the second generations by second clients of the plurality of clients, the second clients being different from the first client; and

performing a configuration of a network device using the new configuration information.

6. A method of managing configuration information of a network device, the method comprising:

storing by a computer, when configuration information is updated by one client of a plurality of clients, the updated configuration information, generation information on a generation of the updated configuration information, and identification information of the one client in association with one another in a storage unit;

generating, when restoration to a first generation is requested by a first client of the plurality of clients, new configuration information with reference to information stored in the storage unit, the new configuration information not including first contents of first updates made by the first client in second generations later than the first generation and including second contents of second updates made in the second generations by second clients of the plurality of clients, the second clients being different from the first client; and

performing a configuration of the network device using the new configuration information.
