Simplifying SDN Control with Automatic Switch Property Inference and Performance Optimization
A major benefit of software-defined networking (SDN) over traditional networking is simpler and easier control of network devices. The diversity of SDN implementation properties, which include both diverse switch hardware capabilities and diverse control plane software behaviors, however, can make it difficult to understand and/or to control the switches in an SDN network. We will explore the issues of understanding and optimization of SDN control, in the presence of different SDN switches and NICs. We will introduce a novel, proactive probing engine that infers key switch capabilities and behaviors of SDN devices, and optimize its controller performance.
