Abstract:
The OpenFlow architecture is a proposal from the Clean Slate initiative to define a new Internet architecture where the network devices are simple, and the control and management plane is performed by a centralized controller. The simplicity and centralization architecture makes it reliable and inexpensive, but the centralization causes problems concerning controller scalability. An OpenFlow controller has two operation paradigms: reactive and proactive. The performance of both paradigms were analyzed in different known controllers. The performance evaluation was done in a real environment and emulation. Different OpenFlow controllers and distinct amount of OpenFlow devices were evaluated. The analysis has demonstrated the shortcoming of reactive approach. In conclusion, this paper indicates the effectiveness of a hybrid approach to improve the efficiency and scalability of OpenFlow architecture.
