Network Slicing in Software DefinedNetworking for 5G

Abstract

Abstract Network slicing stands out as a crucial feature of software-defined networks (SDN), playing a pivotal role in the deployment of 5G networks amid the current era of technological advancement. This capability empowers operators to manage multiple virtual networks atop a shared physical infrastructure. Service providers can thereby segment their network resources into distinct logical networks, each tailored to meet the specific requirements of diverse users or services. As 5G deployment progresses, network function virtualization (NFV) and software-defined networking (SDN) are poised to steer the implementation of network slicing. In this review, I provide an overview of SDN in the context of 5G, exploring the role, motivation, and recent advancements in network slicing. The review further delves into the application scenarios of SDN within network slicing for 5G. The proposed architecture for network slicing in software-defined networking (SDN) for 5G networks encompasses three key usage scenarios: enhanced mobile broadband (eMBB), ultra-reliable low-latency communications (URLLC), and massive machine-type communications (mMTC). Conclusively, this report outlines challenges and suggests future research directions focused on network slicing in the context of 5G.
