Abstract
There is manifold increase in global Internet traffic with the advancement of time and provision of ubiquitous Internet access efficiently in terms of Quality of Service and Experience (QoS and QoE) is a serious challenge for the service provider with existing conventional network technology. With Software Defined Optical Wireless Networking (SDOWN) technology world seems to move toward the Next Generation Network (NGN) which exposes itself to resolve many limitations of a conventional/traditional manually operated optical-wireless network via software-assisted and efficient network control through centralized controller. In this research paper, a layered and logical architecture of the proposed SDOWN model and mathematical analysis are presented. The paper also elucidates the implementation of SDOWN model with and without SDOWN Controller with the help of block and state diagrams. Besides, in this model OpenFlow (OF) governed six (06) MATLAB components has been designed such as SDOWN Controller, Ethernet switch-1 & 2, Optical switch-1 & 2, and Wi-Fi access point with suitable interfaces. Software Defined Networking (SDN) Controller interfacing with optical-wireless network i.e. SDOWN and its performance analysis have been carried out with the state-of-the-art (SotA), where pseudo codes of algorithms and flowcharts for the same are duly explained, which provides Unified Control Plane (UCP) via SDOWN Controller for better QoS and QoE. Simulation results and discussions with suitable Figures have also been presented.
