Software Defined Network-Based Management for Enhanced 5G Network Services

Abstract

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.

Modeling and Evaluation of Software Defined Networking Based 5G Core Network Architecture

“…However, the authors did not provide any simulation or prototype-based performance evaluation of their architecture. Tadros et al [28] study different control plane architectures in 5G networks and compare them in terms of throughput and latency. The three architectures presented in this work are centralized, distributed, and locally centralized-physically distributed (LC-PD) control plane architectures.…”

Algorithmics and Modeling Aspects of Network Slicing in 5G and Beyonds Network: Survey

“…5G networks are intended to provide a full connection between communities that can overcome the constraints of time and space as well as the creation of whole dimensional interconnections between people and things [4]. Also, the 5G network has to support several services [5], business models [6], and multiple slices sharing the same infrastructure to attain complete resource usage, finest level of granularity, and satisfy the distinct scenarios. Backing all these demands in the same infrastructure necessitates re-engineering of the network architecture beyond the present 3rd Generation Partnership Project [7]-Long Term Evolution [8] (3GPP-LTE) extensions.…”

Management of Software-Defined Networking Powered by Artificial Intelligence

“…On the other hand, Software Defined Networking (SDN) [1][2][3][4][5] has revolutionized network management by separating data and control planes. The data plane is composed of forwarding devices, for example routers, switches, etc.…”
