Abstract

Mechanisms for managing a first unit and one or more other units connected to the first unit over a network are provided. The mechanisms detect, by a management unit, an operating state of the other units positioned within a specific range from the first unit on the basis of a location of each of the first and other units over the network. The operating state includes at least an operating state at which a service request is capable of being transmitted to the first unit. The mechanisms further transmit, by the management unit, to the first unit, an instruction to change an operating state of the first unit depending on a number of the other units being in the detected operating state at which the service request is capable of being transmitted.

Claims

1. A method for managing a first unit and a plurality of other units connected to the first unit over a network, the network being connected to a management unit, the method comprising:

detecting, by the management unit, an operating state of a subset of the plurality of other units positioned within a specific range from the first unit on the basis of a location of each of the first unit and the plurality of other units over the network, the operating state including at least an operating state at which a service request is capable of being transmitted to the first unit; and

transmitting, by the management unit, to the first unit, an instruction to change an operating state of the first unit depending on a number of the subset of other units being in the detected operating state at which the service request is capable of being transmitted, wherein the first unit is an image forming apparatus, and the plurality of other units are configured to transmit an image forming service request to the first unit and wherein the location of each of the first unit and the plurality of other units is expressed as a distance from the management unit.

2. The method according to claim 1, wherein, when the determined number is larger than a specific number, the instruction is transmitted by the management unit to the first unit, the instruction causing the first unit to shift from an operating state at which first power consumption is indicated, to an operating state at which second power consumption is indicated, the second power consumption being larger than the first power consumption.

3. The method according to claim 1, wherein, when the determined number is smaller than a specific number, the instruction is transmitted by the management unit to the first unit, the instruction causing the first unit to shift from an operating state at which first power consumption is indicated, to an operating state at which second power consumption is indicated, the second power consumption being smaller than the first power consumption.

4. The method according to claim 3, further comprising:

acquiring the specific range and the specific number associated with the first unit from a data structure storing entries for a plurality of first units, wherein the specific range and the specific number are different for at least two of the first units in the plurality of first units.

5. The method according to claim 1, wherein the plurality of other units are application software.

6. The method according to claim 1, wherein the plurality of other units are computers.

7. The method according to claim 1, wherein the location of each of the first unit and the plurality of other units is expressed by an identifier for a network segment in the network.

8. An apparatus for managing a first unit and a plurality of other units connected to the first unit over a network, the apparatus comprising:

a client unit management section that detects an operating state of a subset of other units in the plurality of other units positioned within a specific range from the first unit on the basis of a location of each of the first unit and the plurality of other units over the network, the operating state including at least an operating state at which a service request is capable of being transmitted to the first unit; and

an integrated control section that transmits, to the first unit, an instruction to change an operating state of the first unit depending on a number of the subset of other units being in the detected operating state at which the service request is capable of being transmitted, wherein the first unit is an image forming apparatus, and the plurality of other units are configured to transmit an image forming service request to the first unit and wherein the location of each of the first unit and the plurality of other units is expressed as a distance from the management unit.

9. The apparatus of claim 8, wherein, when the determined number is larger than a specific number, the instruction is transmitted by the management unit to the first unit, the instruction causing the first unit to shift from an operating state at which first power consumption is indicated, to an operating state at which second power consumption is indicated, the second power consumption being larger than the first power consumption.

10. The apparatus according to claim 8, wherein, when the determined number is smaller than a specific number, the instruction is transmitted by the management unit to the first unit, the instruction causing the first unit to shift from an operating state at which first power consumption is indicated, to an operating state at which second power consumption is indicated, the second power consumption being smaller than the first power consumption.

11. The apparatus according to claim 8, wherein the plurality of other units are application software.

12. The apparatus according to claim 8, wherein the plurality of other units are computers.

13. The apparatus according to claim 8, wherein the location of each of the first unit and the plurality of other units is expressed by an identifier for a network segment in the network.

14. A computer program product for managing a first unit and a plurality of other units connected to the first unit over a network comprising a computer readable storage device having a computer readable program stored therein, wherein the computer readable program, when executed on a computing device, causes the computing device to:

detect an operating state of a subset of other units in the plurality of other units positioned within a specific range from the first unit on the basis of a location of each of the first unit and the plurality of other units over the network, the operating state including at least an operating state at which a service request is capable of being transmitted to the first unit; and

transmit, to the first unit, an instruction to change an operating state of the first unit depending on a number of the subset of other units being in the detected operating state at which the service request is capable of being transmitted, wherein the first unit is an image forming apparatus, and the plurality of other units are configured to transmit an image forming service request to the first unit and wherein the location of each of the first unit and the plurality of other units is expressed as a distance from the management unit.

15. The computer program product of claim 14, wherein, when the determined number is larger than a specific number, the instruction is transmitted by the management unit to the first unit, the instruction causing the first unit to shift from an operating state at which first power consumption is indicated, to an operating state at which second power consumption is indicated, the second power consumption being larger than the first power consumption.

16. The computer program product according to claim 14, wherein, when the determined number is smaller than a specific number, the instruction is transmitted by the management unit to the first unit, the instruction causing the first unit to shift from an operating state at which first power consumption is indicated, to an operating state at which second power consumption is indicated, the second power consumption being smaller than the first power consumption.

17. The computer program product according to claim 14, wherein the plurality of other units are application software.

18. The computer program product according to claim 14, wherein the plurality of other units are computers.

19. The computer program product according to claim 14, wherein the location of each of the first unit the plurality of other units is expressed by an identifier for a network segment in the network.
