19th, NFV functional entitys according to claim 15, it is characterised in that the NFV functional entitys are the NFVO, then the NFVO also includes：

Memory module, the information for storage hardware clock；

Second determining module is specific:According to the information of the hardware clock of storage, the hardware clock address that the VNF can be accessed directly is determined.

20th, NFV functional entitys according to claim 19, it is characterised in that the NFV functional entitys are the NFVO, then the NFVO also includes： 4th determining module, after determining the hardware clock address that the NFV can be accessed directly according to second determining module, determines the VNF to the access cycle of the hardware clock address and accesses duration.

21st, the NFV functional entitys according to claim 18 or 20, it is characterized in that, the NFV functional entitys are the NFVO, the then sending module, it is additionally operable to be sent to after the VNF by the address of the hardware clock, the VNF is sent to the VNF to the access cycle of the hardware clock address and access duration.

22nd, NFV functional entitys according to claim 15, it is characterised in that the NFV functional entitys are the NFVO, then the NFVO also includes：

5th determining module, for, according to the tick interrupt accuracy requirement, being before the VNF determines hardware clock address, according to the tick interrupt accuracy requirement of the VNF, it is determined that meeting the VIM of the VNF demands resource in the second determining module;

The sending module is additionally operable to：Resource reservation request is sent to the VIM；

Also include the second receiving module, carry the mark of physical equipment in the resource reservation result that the VIM is returned, the resource reservation result for receiving.

23rd, NFV functional entitys according to claim 22, it is characterised in that the NFV functional entitys are the VNFM, then the VNFM also includes：Also include：Request module, for being received in the 5th determining module in the resource reservation result that the VIM is returned, the resource reservation result after the mark of carrying physical equipment, the request VIM creates and started virtual machine.

24th, the NFV functional entitys according to claim 22 or 23, it is characterised in that described

NFV functional entitys are the NFVO, and the resource reservation result includes：The hardware clock address；Second determining module specifically for：The hardware clock address is obtained from the resource reservation result.

25th, NFV functional entitys according to claim 24, it is characterised in that also include in the resource reservation result：The VNF is to the access cycle of the hardware clock address and accesses duration.

26th, NFV functional entitys according to claim 24, it is characterised in that the NFV functional entitys are the NFVO, then the NFVO also includes：

6th determining module, after obtaining the hardware clock address from the resource reservation result according to second determining module, determines the VNF to the access cycle of the hardware clock address and accesses duration. 27th, a kind of network function virtualization NFV functional entitys, it is characterised in that including：Processor and memory, the memory storage execute instruction, when the acquisition system operation of the clock interrupt signal, communicated between the processor and the memory, execute instruction described in the computing device causes the acquisition system of the clock interrupt signal to perform the method as described in any one of claim 1 13.
