Design of SDN-Enabled Cloud Data Center

Software Defined Networking (SDN) technology has been considered an effective solution to cope with the various challenges of a cloud data center, such as high throughput, network virtualization, fast fault detection and recovery, and load balancing. Although some research have adopted a specially designed infrastructure, such as Fat tree, to simplify the aforementioned challenges, as most data centers still adopt a multi-rooted tree as the underlying infrastructure topology due to its flexibility and rapid development of high speed switches. In this paper, we present a novel design of an SDN-enabled cloud data center which addresses important traffic engineering issues, that includes auto topology discovery, auto addressing, auto routing, load balancing, and fast fault detection and recovery. We then evaluate our design via real implementation as well as the Mininet simulations.
