由于通信技术的快速发展和产生大量数据的物联网（IoT）设备的新兴使用，引入第五代（5G）移动的网络来支持这种发展。该移动的网络可以在蜂窝电话中提供许多高级通信特征。但不幸的是，这项技术面临着许多挑战。其缺陷之一是管理大量运行不同服务的设备，因此软件定义网络（SDN）被提出作为克服这一缺陷的关键技术。SDN架构在5G移动的网络中提供更高的灵活性、可扩展性、成本效益和能源效率。SDN控制平面通常有不同的架构。我们研究了其中的一些架构，并调和了5G网络中逻辑集中-物理分布式（LC-PD）控制器管理架构的使用。与其他控制平面架构相比，该架构能够提供更高的吞吐量和更低的延迟。在本文中，我们重点展示了LC-PD控制平面架构提高了5G移动的网络中运行互联网服务的通信效率和服务质量（QoS）。我们在模拟测试中使用Mininet-WIFI仿真器。我们进行的模拟表明，与其他SDN实现相比，在5G网络中采用LC-PD控制平面架构可以提高互联网服务的QoS。
Due to the fast development in communication technology and the emerging usage of Internet of Things (IoT) devices that produce a huge amount of data, the fifth generation (5G) mobile network is introduced to support this development. This mobile network can provide many advanced communication features in cellular phones. But unfortunately, this technology faces many challenges. One of its defective challenges is the management of a massive number of devices running different services, so Software Defined Network (SDN) is proposed as a key technology to overcome this drawback. SDN architecture provides higher flexibility, scalability, cost-effectiveness, and energy efficiency in 5G mobile networks. There are usually different architectures for the SDN control plane. We study some of these architectures, and we conciliate the usage of Logically Centralized-Physically Distributed (LC-PD) controller management architecture in 5G networks. This architecture enables providing higher throughput, and lower latency compared to other control plane architectures. In this paper, we focus on the demonstration that the LC-PD control plane architecture improves communication efficiency and the Quality of Services (QoS) of running internet services in the 5G mobile network. We use the Mininet-WIFI emulator in our simulation tests. Our conducted simulations show that employing the LC-PD control plane architecture in 5G networks enhances the QoS of Internet services compared to other SDN implementations.
