SDN-Based Enhancements to QoS and Data Quality in Multi-Tenanted Data Center Clouds

I am currently in Berlin, presenting 3 of my papers at IC2E conference at TU Berlin. Given below is my doctoral symposium paper presentation, which basically summarizes the progress of my PhD during these first two years of my EMJD-DC life.

Abstract: Tenants assume various roles in the enterprise data center networks, requiring a differentiated Quality of Service (QoS), data quality and isolation guarantees among them. Traditionally, data storage and processing are handled in either distributed, or centralized manner. While distributed execution offers a higher horizontal scalability, it often comes with a trade-off of lack of centralized control, and hence often with a decreased accuracy and management efficiency.

Software-Defined Networking (SDN) offers a global view of the entire data center network to a logically centralized controller. Hence, it provides the best of both worlds with minimal compromises: (i) scalability of the large-scale distributed systems. (ii) unified management capabilities of the traditional centralized systems. By deploying an extended SDN controller architecture, we attempt to enhance the data quality of stored and processed data and increase the QoS of the multi-tenanted data center network clouds.
