Use case-based evaluation of software defined networking controllers
type: CreativeWork
description: The paradigm of Software Defined Networking (SDN) model has arisen as a viable candidate to tackle traffic management and costs based problems in developing markets. At the root of SDN is the control system that responsible for overseeing resource orchestration premised around its global understanding of the existing resource utilization of the network. A significant problem that needs to be resolved in the early implementation of an SDN-based network configuration is where each controller and switches are located to ensure the optimal operational performance. It is critical to note that the placement and size of the data plane devices have a direct impact on the overall performance of the SDN controller. This problem represents conflicting priorities, such as delay, dynamic routing and efficiency. In order to address the controller performance problem and formulate a strategy for the deployment of SDN in emerging markets, the study proposes solutions that provide flexibility, ease of management, traffic engineering and network distribution with the aim of reducing delay and of enabling efficient network utilization. There are important questions that should be answered during transitioning to an SDN solution, and those questions are: Given a legacy WAN, how many SDN controllers and switches are required? How should they be placed? Where are the best locations to place them? And how efficient are they in terms of traffic engineering so that the overall network performance is optimized? Henceforth, we will refer to these questions as the switch-tocontroller performance problem. The average latency was reduced to 15% compared to that of the Optimized K-means. The proposed method was also successful in the throughput (with an improvement of 13%). The studied metrics on RTT and throughput showed improvement in the reliability test equal to averages of 1.182 and 2.166 ms with two and three-controller deployment respectively and a throughput average of 20 GB/s.
