【摘要】：当今几乎所有大中型机构都建立了自己的数据中心，随着企业全球性竞争的加剧，数据中心网络正在变得过于复杂、昂贵和低效。传统的数据中心网络架构需要借助过多的交换层才能解决性能低下和平台密度低下等问题。用户和应用数量的增长通常会导致"孤立"设备的增加，同时也为网络的可靠性和安全性带来了挑战。所以如何设计新一代数据中心网络架构，使其能满足企业的各种需求成为一个关键的问题。本论文探讨了数据中心网络建设的重要性，以及传统数据中心网络架构的局限性。论文结合企业整体网络规划，对数据中心网络架构进行设计，以适应企业对高可靠、安全运行、提升IT管理水平的需求。数据中心网络架构总体设计思路为“核心-边缘”架构，将数据中心网络划分为核心交换区和业务功能区两层结构。按照网络核心、汇聚和接入的模型对数据中心每一个功能区进行划分，然后通过网络分区设计方法定义核心区与各个边缘功能区。这样单个应用访问主要在一个区域内部完成，单个区域故障仅影响一类应用。本论文运用当前主流网络技术如万兆技术、网络虚拟化等，结合企业对业务增长、数据安全、不间断服务的需求，设计新一代数据中心网络架构。本论文研究的成果在于设计新一代企业数据中心网络架构，，让数据中心网络成为高性能、融合业务统一交换的基础平台。本论文设计的数据中心网络架构，增强了业务的可扩展性、网络的安全性，提高网络的可靠性。经过测试该网络架构满足企业对网络的各种需求。
[Abstract]:Today, almost all large and medium-sized organizations have established their own data centers. As global competition intensifies, the network of data centers is becoming too complex, expensive and inefficient. Traditional data center network architecture needs too many switching layers to solve the problems of low performance and low platform density. The increase in the number of users and applications often leads to an increase in "isolated" devices, as well as challenges to the reliability and security of networks. So how to design a new data center network architecture to meet the needs of enterprises becomes a key issue. This paper discusses the importance of data center network construction and the limitations of traditional data center network architecture. This paper designs the network architecture of data center based on the whole enterprise network planning to meet the demand of high reliability, safe operation and improving IT management level. The overall design idea of data center network architecture is "core-edge" architecture. The data center network is divided into two layers: core switching area and service function area. According to the network core, convergence and access model, each function area of the data center is divided, and then the core area and each edge function area are defined by the method of network partition design. Such a single application access is mainly done within a single area, and a single area fault affects only a class of applications. In this paper, the current mainstream network technologies such as multi-megabit technology, network virtualization and so on are used to design a new generation of data center network architecture, which combines the demand of business growth, data security and continuous service. The achievement of this paper is to design a new generation of enterprise data center network architecture, so that the data center network becomes the basic platform of high performance and integrated service exchange. The data center network architecture designed in this paper enhances the expansibility of the service, the security of the network and the reliability of the network. After testing the network architecture to meet the needs of the enterprise network.
