Abstract:
One of the main causes of the demise of deep-rooted networks has been the explosive expansion of internet service providers and current data traffic. The core idea of Software Defined Network (SDN) is the separation of the control and data planes. The Pareto Optimal Controller Optimization Placement (POCO) framework is used in two situations for the optimization: failure-free controller placement and when either nodes or controllers fail. The location of the controller in the aforementioned scenariosfor various K-controller counts was first discovered and examined for both controller imbalance and fault tolerance. First, the controllers' placement in the aforementioned scenarios for different numbers of K controllers was found and investigated. Following this, results of different metrics like latencies (Controller-to-controller and Node-to-controller),fault tolerance (for either node or controller failures), and controller imbalance for both the aforesaid scenarios were conducted accordingly. From the results, it is recommended that the minimum number of controllers required to adopt SDN in Addis Ababa University campus networks be two controllers, considering the resiliency of controllers placed at Sidist kilo and A rat kilo. Also, we conclude that the POCO performance analysis under the failure-free scenario-based experiment showed minimum latency compared to the worst-case scenario (node failure and up to K-1 controller failure). But showed minimum node failure Controller-to-controller latency compared to the failure-free scenario.
