By modifying the current LTE architecture and integrating OpenFlow to the 5G architecture, it promises to fulfil the requirements of the end-users and to achieve better performances. This research presents SDN-based 5G network architecture to support next generation mission critical services. SDN allows for better evolvability of the data plane without depending on a slew of management or control protocols, allows for centralized control of the overall infrastructure, and allows for a richer feature set based on its programmable nature. The proposed architecture is characterized by a clear separation of the control and data planes that provides a latency improvements up to 75% compared to 3GPP Release 12 compliant 4G systems. Keywords- Defined Networking (SDN), 5G NETWORK, Latency, Quality of Service, Latency, management plane. I. INTRODUCTION Mobile The information and communication technologies continue to evolve from the analogue-based first generation of wireless mobile telecommunications network to current broadband LTE network. Mobile subscriptions have expanded which prompts a higher interest in proficient transmissions, portability, and lower latency throughout the most recent decade. The first generation came up with the basic voice message services where all the components were analog systems, while the second era was essentially utilized for voice correspondence and gives further administrations like SMS and email where TDMA and CDMA advanced modulation plans are utilized. Third generation set up portable broadband and gives individual mobile Internet administrations join rapid mobile access with Internet Protocol-based administrations. The fourth and current age (4G/LTE) incorporates every internet. [1][2]. The focus of the fifth-generation mobile communication is to give consistent correspondence to machines and gadgets fabricating the Internet-of-Things (IoT) alongside the individual correspondence [3, 4]. The goal is to structure the best remote world that is free from containments and hindrance of the past ages. Software Defined Networking (SDN) is an engineering where the system control plane is physically isolated from the data plane and a control plane (CP) can control a few devices. SDN gives off an impression of being a promising innovation to give adaptable nature of services and exceptionally low latency [5][6]. The necessities in 5G remote frameworks is to limit the bundle transmission latency for Ultra-Reliable Low Latency Communication (URLLC) administrations, for example, vehicle-to-everything (V2X) interchanges. Low latency in cell systems is an essential for making self-driving vehicles safe. The new design is expected to accomplish better exhibitions while taking part to the network functions virtualization by incorporating OpenFlow (SDN protocol).
