In the era of cloud computing, a hierarchal network design in a traditional data center can no longer keep up with the requirements in terms of increased bandwidth and different traffic characteristics. In this talk, I will first present the challenges that a traditional data center network architecture faces. I’ll then share the rationality in choosing and designing the next generation network architecture to address those challenges and bring 10G network to the host level. Finally, I’m going to present the demand of a SDN-based solution to deploy, monitor and troubleshoot this new network architecture which comes with vastly increased number of switches, viable routes and configuration changes.
