Description
Technical Field
The present invention relates to the field of network function virtualization technologies, and in particular, to a network function virtualization system and method.
Background
At present, network function virtualization is a concept of network architecture, and utilizes virtualization technology to divide the network node level functions into several functional blocks, which are implemented in a software manner, and are not limited to a hardware architecture. At the heart of network function virtualization is the virtual network function. It provides network functions that can only be found in hardware, including many applications such as routing, CPE, mobile core, IMS, CDN, ornamentation, security, policy, etc.
However, the virtualized network functionality requires the integration of applications, business processes, and infrastructure software that can be integrated and adapted. The goal of network function virtualization technology is to provide network functions on standard servers, rather than on custom devices, without the ability to perform the functional instructions in a true sense.

In order to achieve the purpose, the invention adopts the following technical scheme:
a network function virtualization system and method includes the following steps:
s1, starting a virtualized network functional entity, creating at least one system task through the virtualized network functional entity, and naming the system task as a command;
s2, the execution command transmits a signal to an input module through an input interface of the system and stores the signal in a corresponding storage unit;
s3, the central processing unit of the network function virtualization system is a receiving processing module;
s4, the receiving processing module sends the function instruction to the detection module, and the detection module detects whether the received instruction is executed;
s5, the detection module transmits the instruction to the output module and continues to execute the subsequent task;
s6, the detection module transmits the command to the input module, stores the command which is not refreshed in the storage unit again, and repeats the steps of S3 and S4 until the central processing unit finishes refreshing the state of the storage unit;
s7, after the detection module transmits the function instruction to the output module, the function instruction is sent to the virtualized network function entity through the output interface of the network function virtualization system;
and S8, after receiving the function instruction of the output module, the virtualized network function entity drives the corresponding peripheral equipment through the output circuit to execute the function instruction.
As a still further scheme of the invention: the receiving and processing module scans the user program according to the logic sequence, and simultaneously performs logic operation to refresh the corresponding state of the execution command in the storage area.
As a still further scheme of the invention: the judgment of the detection module on the functional instruction shows that the state refreshing of the central processing unit on the storage unit is completed, and the instruction is transmitted to the output module.
As a still further scheme of the invention: and the detection module judges whether the functional instruction is negative, which indicates that the state refreshing of the central processing unit to the storage unit is not finished, and the instruction is transmitted to the input module.
The invention has the beneficial effects that: the virtualized network function entity inputs signals, receives a function instruction issued by the central processing unit through the output module, can complete the execution of the function instruction through corresponding external equipment, performs specific execution steps on the function instruction, and realizes the output of the instruction in a real sense by means of the cooperation of hardware.
