Question

Openflow/SDN networks gives a remote controller the ability to manage the behavior of network devices i.e. configurations. They can forward instruction sets to dynamically change network configuration. But there is always some room for bugs and failures in your SDN controller application. What i am getting is that i had to painstakingly dig through logs to find the one or two inputs that lead my controller software to break. What are the best testing practices for controller code i.e. traffic simulator, stress testing etc

Answer 1

there is a company called Ixia who provides Ethernet testing SW and HW. They have a comprehensive portfolio to test OpenFlow/SDN. They are also the chair of Openflow industry body.
