【摘要】：云计算的快速发展也推进了数据中心的变革。云计算环境下的数据中心与传统数据中心的差异主要体现在大规模的组网、虚拟机迁移和能够实现多租户共享网络资源池这三项特征。伴随着随取随用的云模式的普遍,云数据中心的存在不仅极大地方便了人们生活,还最大化的利用了有限的资源,所以说,云数据中心拥有着广阔的发展前景。当然,伴随着云数据中心的普及,其网络防攻击也愈发受到重视。本文首先给出云计算的概念,从计算模式的发展进步开始分析了云计算较之集中式处理模式和分布式处理模式的优势。发展云计算之后,数据中心作为云计算的承载必须能够提升数据处理和流量交换能力以满足云计算的多业务高计算量需求,与此同时,数据中心的网络安全成为了人们关注的焦点。对于新形势下云数据中心存在的网络攻击,陈述了网络攻击的现状及特点,为下文的研究工作做好铺垫。对以太网中常见的网络攻击,首先进行协议工作原理的介绍,然后对于怎样针对不同的协议发起攻击的方法进行了条理清晰的分析,最后就如何在测试中进行攻击防范操作结合自己的测试过程,给出了防范的方法及各方法在实测时的使用效果对比。另外,本文还类比于传统的数据中心组网,对云数据中心的架构、组网特性及所需技术都做出了分析介绍。在对云数据中心网络有了较好的理解之后,对测试任务进行了需求分析,列出了本测试任务中的重点、难点及注意事项。针对云计算环境下数据中心的模型,进行了多种网络攻击的模拟,测试了常见网络攻击以及云数据中心下新特性的稳定性,每部分的测试内容都附有自己的分析和实测操作说明。最后,引进了 TCL脚本语言,对于云数据中心的MDC特性进行自动化测试模块的开发。
[Abstract]:The rapid development of cloud computing also promotes the change of data center.The difference between the data center and the traditional data center in cloud computing environment is mainly reflected in the three characteristics of large-scale networking, virtual machine migration and the ability to realize multi-tenant shared network resource pool.With the popularity of the cloud pattern, the existence of cloud data centers not only greatly facilitates people's lives, but also maximizes the use of limited resources. Therefore, cloud data centers have a broad development prospects.Of course, with the popularity of cloud data centers, its network attack prevention has been paid more and more attention.This paper first gives the concept of cloud computing, and analyzes the advantages of cloud computing compared with centralized processing mode and distributed processing mode from the development and progress of computing model.After the development of cloud computing, the data center as the carrier of cloud computing must be able to enhance the capacity of data processing and traffic exchange to meet the high computing requirements of cloud computing, at the same time,The network security of data center has become the focus of attention.For the network attack in the cloud data center under the new situation, the present situation and characteristics of the network attack are stated, which will pave the way for the research work below.The common network attacks in Ethernet are introduced at first, then the methods of attacking against different protocols are analyzed methodically.Finally, on how to carry on the attack prevention operation in the test to combine own test process, has given the guard method and the each method in the actual measurement use effect comparison.In addition, this paper also compares to the traditional data center networking, and analyzes the structure, network characteristics and the required technology of cloud data center.After a better understanding of the cloud data center network, the requirements of the test task are analyzed, and the key points, difficulties and points for attention in the test task are listed.Aiming at the model of data center in cloud computing environment, several network attacks are simulated, and the stability of common network attacks and new features under cloud data center is tested.Each part of the test is accompanied by its own analysis and actual operation instructions.Finally, TCL script language is introduced to develop the automatic test module for the MDC feature of cloud data center.
