Infrastructure of data centers for transferring big data traffic: A survey research

Big data make drastic changes in patterns of data center traffic. In traditional applications, which are based on client-server architectures, data center traffic are in northern-southern mode. While, as applications of big data developed, so-called eastern-western traffic patterns were widely used in data center networks. Moreover, applications of cloud computing technology in processing infrastructures and data center storage have made dynamic network traffic in such centers. Large volume of eastern-western data, changes in traffic patterns in a dynamic manner, and immediate nature are among importance characteristics of application of big data in data center networks that have posed several challenges to traditional architecture and data center technologies. This is, therefore, essential to make drastic changes in network infrastructure of data centers to execute several applications of big data. In this article, attempts are made to focus on network issues and requirements for big data, addressing recent methods and technologies in order to solve network problems. We, in addition, analyzed application and impact of modern technologies such as software-defined networks in applications relevant to big data.
