Abstract

A resource request is continuously accepted within predetermined time by a resource management device that comprises a resource request accepting unit, a measuring unit, and an allocating unit. The resource request accepting unit accepts a resource request that is necessary for communication. The resource request includes priority of communication. The measuring unit measures the accepting time when the resource request accepting unit accepts the resource request. The allocating unit allocates resource to the resource request accepted in accepting time based on priority. As a result, suitable resource allocation according to the priority instead of the order of arrival is realized.

Claims

1. A resource management device comprising:

a resource request accepting unit operable to accept resource request possessing priority to request a resource;

a measuring unit operable to measure accepting time for which said resource request accepting unit can accept the resource request; and

an allocating unit operable to allocate the resource according to the priority for the resource request accepted by said resource request accepting unit in the accepting time.

2. The resource management device as claimed in claim 1, wherein said measuring unit measures time elapse for predetermined time defined as the accepting time since said resource request accepting unit has accepted the resource request.

3. The resource management device as claimed in claim 1, wherein said allocating unit allocates the resource for the resource request in order of the priority.

4. The resource management device as claimed in claim 1, wherein said resource request accepting unit further comprises:

a holding unit operable to hold the resource request temporarily.

5. The resource management device as claimed in claim 4, wherein, when the resource request held by said holding unit is greater in number than a predetermined number, said allocating unit allocates the resource for the resource request according to the priority.

6. The resource management device as claimed in claim 1, further comprising:

a collecting unit operable to demand the resource request.

7. A resource management system comprising:

a plurality of communication devices, one communication device of said plurality of communication devices being operable to communicate, using a resource, with another communication device of said plurality of communication devices; and

a resource management device operable to manage the resource,

wherein each of said plurality of communication devices comprises;

a resource request transmitting unit operable to transmit resource request possessing priority to request the resource; and

a communication unit operable to communicate with a partner communication devices among said plurality of communication devices,

wherein said resource management device comprises;

a resource request accepting unit operable to accept the resource request transmitted by said resource request transmitting unit; and

an allocating unit operable to allocate the resource for the resource request according to the priority.

8. The resource management system as claimed in claim 7, wherein said resource management device further comprises:

a measuring unit operable to measure accepting time for which said resource request accepting unit is allowed to accept the resource request, and

wherein said allocating unit allocates the resource according to the priority for the resource request accepted by said resource request accepting unit in the accepting time.

9. The resource management system as claimed in claim 7, wherein said resource request accepting unit further comprises:

a holding unit operable to hold the resource request temporarily,

wherein, when the resource request held by said holding unit is greater in number than a predetermined number, said allocating unit allocates the resource for the resource request.

10. The resource management system as claimed in claim 7, wherein said resource management device further comprises:

a collecting unit operable to output notifying signal to ask said plurality of communication devices to transmit resource request, and

wherein said plurality of communication devices transmit respective resource request in order of priority after receiving the notifying signal.

11. The resource management system as claimed in claim 10, wherein, when no resource request is received in said resource management device after transmitting the notifying signal, said collecting unit transmits another notifying signal.

12. The resource management system as claimed in claim 10, wherein each of said plurality of communication devices further comprising:

a measuring unit operable to measure waiting time defined by the priority, and

wherein said resource request transmitting unit transmits the resource request after the waiting time.

13. The resource management system as claimed in claim 12, wherein said measuring unit starts to measure the waiting time after receiving the notifying signal.

15. The resource management system as claimed in claim 12, wherein, when one of said plurality of communication devices has a plurality of resource requests possessing different levels of priority, the one of said plurality of communication devices transmits the plurality of resource requests in order of the priority level.

14. The resource management system as claimed 12, wherein the waiting time in a case where said communication device possesses the resource request possessing high priority is shorter than the waiting time in a case where said communication device possesses the resource request possessing low priority.

16. A resource management method comprising:

accepting resource request that includes priority of communication and requests a resource necessary for communication;

finishing said accepting after predetermined time; and

allocating, according to the priority, the resource for the resource request that is accepted in the predetermined time.

17. The resource management method as claimed in claim 16, wherein said allocating allocates the resource for the resource request in order of the priority.

18. The resource management method as claimed in claim 16, wherein, when the resource request accepted by said accepting is greater in number than a predetermined number, said finishing finishes said accepting.

19. The resource management method as claimed in claim 16, wherein, when another resource request is accepted by said accepting after accepting a certain resource request, said finishing finishes said accepting.
