Review of New Data Center Network Structure

Nowadays, people ’s lives are increasingly inseparable from big data. The development of big data has a profound impact on human society. At the same time, the generation of massive data has promoted the transformation of data processing methods. In this development trend, cloud computing came into being. Cloud computing is to provide online cloud services to network users by building a large shared platform, so as to achieve on demand allocation of resources. Data centers are the core infrastructure of cloud computing, Therefore, the performance of the data center network determines the quality of service provided by cloud computing. However, traditional data center networks have long been unable to meet the needs of today ’s society for large data centers. This paper summarizes the new data center network structure pro-posed in recent years from the aspects of switch-centric, server-centric, wireless data center, wired and wireless combination, introduces its performance, fault tolerant routing efficiency and other advantages, and looks forward to the future development of data center network structure.
