【摘要】：移动互联网已经得到了快速发展,为了适应出现的多样化新需求,提高业务的灵活性和应用的部署速度是运营商急需解决的。但是如今以专有硬件为主流的传统网络架构已经很难以满足这一需求了,所以改变传统网络架构是当前必须要解决的问题。NFV(Network Function virtualization,网络功能虚拟化)最主要的思想就是将传统网络功能进行虚拟化。它通过引入云平台,依靠硬件通用性以及虚拟化技术,来建立各种网络应用。通过软硬件解耦的技术,就可以使得网络设备功能和专用硬件得以分离,没有紧密的联系性。而且设备的资源也能够充分灵活共享,这样就可以快速开发和部署新的业务功能。利用NFV技术,通过使用各个厂商的不同的硬件设备,不必再使业务功能与硬件设备一一对应,所有的业务功能和硬件平台都可以统一进行管理与维护。这对于成本开销来说是减少了相当大的一部分,除此之外,也可以实现资源的灵活调度等功能。同时,以Openstack为代表的开源技术正在成熟,也为实现这种平台提供了一定的技术保障。因此,构建NFV的平台,以及测试平台的功能和性能来说,对于运营商有着重要的意义。本文的主要工作有以下几点:1.对NFV系统架构进行了调研,将其分为三部分的功能模块进行介绍,分别为NFVI、VNFs和MANO。并且描述了各个子功能模块间的接口。在此基础之上,也分析了 OPNFV组织、OPNFV平台、以及它们和NFV的关系。2.对OPNFV组织和项目的相关内容进行了调研,提出了一种基于NFV系统架构和开源技术的平台构建方案。把所要构建的OPNFV平台分为了 NFVI和VIM两部分,使得平台可以精简,快速部署,同时也实现了对云平台资源的综合管理。3.对构建的平台进行了测试验证。测试主要从平台测试来验证。平台测试分为功能测试和性能测试。在平台的功能测试中,本文使用负载均衡测试进行验证,联合了 OPNFV平台的各种功能,实现了负载均衡的实例,以此验证平台的功能;对于平台的性能测试,需要测试系统的性能是否满足要求,对此使用了 Functest来进行测试,将测试得出的结果与OPNFV开源组织测得的标准结果进行对比,通过项目中众多的测试项来验证平台的性能。
[Abstract]:Mobile Internet has been developed rapidly. In order to adapt to the new demand of diversification, it is urgent for operators to improve the flexibility of service and the speed of application deployment. But the traditional network architecture, which is dominated by proprietary hardware, is no longer able to meet this demand. Therefore, to change the traditional network architecture is the problem that must be solved at present. The main idea of network virtualization is to virtualize the traditional network functions. It builds various network applications by introducing cloud platform, relying on hardware generality and virtualization technology. Through the technology of software and hardware decoupling, the network equipment function can be separated from the special hardware without close connection. And equipment resources can be fully and flexibly shared, so that the rapid development and deployment of new business functions. By using the different hardware equipment of each manufacturer, it is not necessary to make the business function correspond to the hardware equipment by using the NFV technology. All the business functions and hardware platform can be managed and maintained in a unified way. This is a significant reduction in cost, in addition to the implementation of flexible resource scheduling and other functions. At the same time, the open source technology represented by Openstack is maturing, which also provides some technical guarantee for the implementation of this platform. Therefore, the construction of NFV platform, as well as the function and performance of the test platform, is of great significance to operators. The main work of this paper is as follows: 1. This paper investigates the architecture of NFV system, and introduces the functional modules which are divided into three parts, namely NFVI VNFs and Mano. The interface between each sub-function module is described. On the basis of this, we also analyze the OPNFV organization's OPNFV platform and their relationship with NFV. 2. 2. This paper investigates the related contents of OPNFV organization and project, and proposes a platform construction scheme based on NFV system architecture and open source technology. The OPNFV platform is divided into two parts: NFVI and VIM. The platform can be simplified and deployed quickly. At the same time, it also realizes the integrated management of cloud platform resources. The platform is tested and verified. The test is mainly verified by platform test. Platform testing is divided into functional testing and performance testing. In the function test of the platform, this paper uses load balancing test to verify, combine the various functions of OPNFV platform, realize the example of load balancing, and verify the function of the platform. We need to test whether the performance of the system meets the requirements. We use Functest to test it, compare the test results with the standard results of the OPNFV open source organization, and verify the performance of the platform through many test items in the project.
