Improving the efficiency of server-centric data center network architectures
Ting Wang, Yu Xia, Dong Lin, Mounir Hamdi · 2014
Data center network architecture is regarded as one of the most important determinants of network performance. As the most typical representatives of architecture design, the server-centric scheme stands out due to its good performance in various aspects. However, there still exist some critical shortcomings in these server-centric architectures. In order to provide an efficient solution to these shortcomings and improve the efficiency of server-centric architectures, in this paper, we propose a hardware based approach, named “Forwarding Unit”. Furthermore, we put forward a traffic aware routing scheme for FlatNet to further evaluate the feasibility and efficiency of our approach. Both theoretical analysis and simulation experiments are conducted to measure its overall performance with respect to cost-effectiveness, fault-tolerance, system latency, packet loss ratio, aggregate bottleneck throughput, and average path length.
