Challenges and opportunities on network resource management in DCN with SDN

With the explosive growth of applications and application traffic, data centers networks are challenged in network utilization and network performance, which is crucial to guarantee the efficiency of computing and storage resources of data center servers. Recently, software defined network has been exploited to manage the network resource in a center controller, which provides opportunities to optimize the network resource utilization. In this paper, we analyze the challenges of the network resource management in data center with software defined network, and point out the opportunities.
