Shuai Gong, Dong Xiaoling, Xiaoyu Yin, Yu Dongbo · 2023
Software Defined Network (SDN) technology provides a new solution to the above problems of cloud data center traffic engineering, virtual machine dynamic migration, load balancing and multi-tenant isolation. This paper firstly expounds the definition and architecture of SDN and analyzes the existing problems of traditional data center network and the functional requirements of data center network in the era of cloud computing. Then this paper establishes the network architecture, basic functions and deployment scheme of data center based on SDN technology. Finally, two key issues in NFV field, general server performance and service chain, are analyzed in detail. The simulation results show that SDN technology can improve the network service ability and reduce the network operation cost.
