[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.
