The present invention provides a method for obtaining a clock interruption signal, and an NFV functional entity. The method comprises: an NFV functional entity determining a clock interruption precision demand of a VNF according to VNFD description information; then, the NFV functional entity determining a hardware clock address for the VNF according to the clock interruption precision demand; and finally, the NFV functional entity sending the determined hardware clock address to the VNF, so that the VNF can access a hardware clock according to the obtained hardware clock address and obtain a clock interruption signal. By using the technical scheme of the present invention, a software clock interruption signal of a user operating system of a virtual machine is generated without calling, by means of the virtual machine, a bottom layer hardware clock interruption signal, and then, the software clock interruption signal is provided to a VNF to enable the VNF to execute a clock signal transmission process of program scheduling, thereby avoiding the delay of the clock signal and the delay jitter, and ensuring the timeliness of the execution of the interruption signal and ensuring that a program is timely scheduled. |
