Abstract :
Software-Defined Networking (SDN) is a viable
approach for management of large and extensive networks
with flexible quality of service requirements and huge data
traffic. Due to the central role of SDN controllers in traffic
engineering and performance of software-defined networks
on one hand, and diversity of available SDN controllers on
the other hand, an evaluation framework is required to study
and compare the architectural choices and performance of
distributed and centralized SDN controllers in action. In this
paper, we propose a comprehensive framework for
performance evaluation of OpenFlow SDN controllers. In
this simulation platform, we analyze both centralized and
decentralized architectures for controller deployment.
Performance of controllers is evaluated based on Quality of
Service (QoS) measures including delay and throughput in
different network topologies under different workloads.
The impact of routing protocols on controller performance
in data center networks is also analyzed. Our results can
provide valuable insights for scalable design and proper
deployment of SDN controllers in the real world scenarios.
