【摘要】：当前,互联网和云计算发展如火如荼,移动互联网的快速兴起以及大数据时代的到来,给网络世界又注入了强大的活力,数据中心作为互联网和云计算的基础已成为研究的热点,面临着巨大的机遇与挑战。数据中心网络是数据中心的核心要件,其既要保障数量众多的高性能服务器发挥其运算能力,又要为用户应用提供可靠高效的数据传输服务。大规模的数据中心网络建设给网络配置管理造成了巨大的压力,重复性的手动配置不仅耗时耗力,而且容易出错,造成难以估量的损失。在数据中心网络初始化过程中,如何快速准确实现自动配置;运维过程中如何便捷高效地实施配置管理,是值得深入研究并加以解决的问题。论文在分析和研究数据中心网络相关技术与研究现状的基础上,针对网络配置管理的关键问题展开深入的研究,论文的主要工作如下:首先,设计并提出数据中心网络配置管理模型CMMDC,该模型采用了松耦合的分层结构,通过各层之间的协同实现配置管理的自动化和可视化。在此基础上进一步提出了基于XML的配置策略统一描述方法,该方法屏蔽了设备厂商配置命令不一致的问题,有效减轻管理员的负担。其次,针对设备接入网络的配置需求,提出了自适应的拓扑发现方法ATD,提高拓扑发现的效率、减轻网络负担;在此基础上,研究并提出了优化的转发策略算法BUD与DUD,能有效避免死锁,实现高效的转发策略配置。最后,设计并实现了数据中心网络配置管理系统CMS,CMS以配置管理模型CMMDC和基于XML的配置策略统一描述方法为基础,向网络管理员提供可视化的配置管理平台,能自动完成配置策略的生成、翻译、执行和验证,大大提高了数据中心网络配置管理的效率。CMS系统部署到实际的数据中心网络环境中测试,验证了CMS系统的运行效果。
[Abstract]:At present, the development of the Internet and cloud computing is in full swing, the rapid rise of mobile Internet and the arrival of big data era, to the network world has injected a strong vitality. As the basis of Internet and cloud computing, data center has become a hot topic, and it faces great opportunities and challenges. Data center network is the core element of data center. It is necessary to ensure a large number of high-performance servers to play its computing power. To provide reliable and efficient data transmission services for user applications, large-scale data center network construction has caused tremendous pressure to network configuration management, repetitive manual configuration is not only time-consuming and labor-intensive. It is easy to make mistakes and cause incalculable losses. How to realize automatic configuration quickly and accurately in the process of data center network initialization; How to implement configuration management conveniently and efficiently in the process of operation and maintenance is a problem worthy of further study and solution. This paper is based on the analysis and research of data center network related technologies and research status. The main work of this paper is as follows: firstly, we design and propose the data center network configuration management model (CMMDC). The model adopts a loosely coupled hierarchical structure and realizes the automation and visualization of configuration management through the cooperation among the layers. On this basis, a unified description method of configuration strategy based on XML is proposed. This method can avoid the problem of inconsistent configuration commands of equipment manufacturers and effectively lighten the burden of administrators. Secondly, an adaptive topology discovery method, ATD, is proposed to meet the configuration requirements of equipment access network. Improve the efficiency of topology discovery, reduce the network burden; On this basis, the optimized forwarding strategy algorithms BUD and DUDare proposed, which can effectively avoid deadlocks and achieve efficient forwarding policy configuration. Finally. The design and implementation of a data center network configuration management system (CMS-CMS) is based on the configuration management model CMMDC and the unified description method of configuration strategy based on XML. Provides the visual configuration management platform to the network administrator, can automatically complete the configuration policy generation, the translation, the execution and the validation. It greatly improves the efficiency of data center network configuration management. CMS system is deployed to the actual data center network environment to test and verify the running effect of CMS system.
