The present invention improves the reliability of execution of a VNF configuration command, reduces the probability of failure in execution of the VNF configuration command, and improves the success rate of instantiation of the VNF.

Description

Virtualized network function VNF optimization method, device and system Technical field

The present invention relates to the field of communication technologies, and in particular, to the field of Network Function Virtualization (NFV); in particular, to a method, device and system for optimizing a virtualized network function VNF.

Background technique

In a traditional network, the network function (NF) is deployed on the hardware unique to each manufacturer. The hardware resources of different vendors and different devices cannot be shared, resulting in waste of resources. NFV technology realizes the virtualization of traditional network functions. Virtualized Network Function (VNF) runs on the cloud. NFV implements the decoupling of VNF and hardware resources. VNF occupies resources on demand, thus improving resources. The utilization efficiency, when the network load is low, will also shut down some servers, which also saves energy and is more environmentally friendly. Compared with the traditional network, the NFV technology manages resources uniformly and manages the VNF. The functions of the NFV technology include: cloud resource management function, VNF management function, and network service management function.

The NFV framework is shown in Figure 1. Compared to traditional networks, NFV introduces the following new network components. These new components and their completed functions are as follows:

Network Function Virtualization Orchestrator (NFVO) is responsible for the lifecycle management of network services, implementing network orchestration, and managing and orchestrating resources of Network Function Virtualisation Infrastructure (NFVI);

Virtualized Network Function Management (VNFM, VNF Manager) is responsible for VNF lifecycle management (eg, instantiation, deletion, viewing, update, scale in/out, scale up/down, self) More (ie, automatically repair VNF), etc., coordinate message processing between VNF and element management (EM, Element Management);

Virtualized Infrastructure Manager (VIM) is responsible for the management (addition, deletion, viewing, update, failure recovery, etc.) of resources (computing resources, storage resources, network resources).

Appendix B.3.1 and B.3.2 of the European Telecommunications Standards Institute standard "GS NFV-MAN 001 V0.5.0 (2014-05)" describe the VNF instantiation scheme. There are three schemes, of which Appendix B.3.1 describes Solution 1: VNF instantiation (NFVO is responsible for allocating resources), see Figure 2; Appendix B.3.2.1 describes scenario 2: VNF instantiation (VNFM is responsible for allocating resources, EM initiates instantiation request), see Figure 3; Appendix B .3.2.2 describes scenario 3: VNF instantiation (VNFM is responsible for allocating resources, NFVO initiates instantiation requests).

It is impossible to do it all at once, if VIM creates VMs immediately after VNF communication and configuration of VNF, it is likely to fail; in the actual commercial process, after testing S213 & S214 & S215 does often fail;

Solution 2 Defect analysis: The three steps of S309&S311&S312 are to communicate and configure with VNF without confirming the successful startup of VNF. It is likely to fail; because after VIM successfully creates VMs, VMs must first load the operating system before they can Install and start your own application software. For the VNF in the telecom field, VNF often contains multiple VMs. These VM operating systems start up and VNF's own application software needs to start up. It is impossible to do it all at once. If VIM creates VMs, it will communicate with VNF immediately. The configuration of the VNF is likely to fail; in the actual commercial process, it is verified that S309&S311&S312 will often fail;

Solution 3 Defect Analysis: The three steps of S410&S412&S413 are to communicate and configure with VNF without confirming the successful startup of VNF. It is likely to fail; because after VIM successfully creates VMs, VMs must first load the operating system before they can Install and start your own application software. For the VNF in the telecom field, VNF often contains multiple VMs. These VM operating systems start up and VNF's own application software needs to start up. It is impossible to do it all at once. If VIM creates VMs, it will communicate with VNF immediately. The configuration of the VNF is likely to fail; in the actual commercial process, it is verified that S410&S412&S413 will often fail.
