Quality of Service Enabled Network Slicing Model in 5G and the Next Generation Virtualized Networks

Exploring the potential of dynamic quality of service cloud-based network slicing in 5G and next generation virtualized networks: A simulation-based study

“…Various research efforts continue to focus on solving different aspects of 5G and next generation network slicing [1]. Our research effort is relevant and gives us an opportunity to contribute towards standards improvement with a view to realizing optimal deployment capability for realistic use cases.…”

“…With the introduction of 5G networks, industry verticals require networks with deterministic service level guarantees through network performance assurances on metrics like packet loss rate, bandwidth, jitter, and latency. 5G networks provide society and industry transformation with a hyper-connected customer experience, new business opportunities, agile and lean network operations across the Core Network (CN), Transport Network (TN), Radio Access Network (RAN), and the cloud [1]. To support various Internet of Things (IoT) type device connectivity with varied services, 5G allows for varied business models, including 3P services, Communication Services Provider (CSP) services, business to business, business vs. consumer, and Mobile Virtual Network Operator (MVNO).…”

“…Our goal is to achieve optimal 5G network slicing that satisfies verticals QoS requirements. A 5G slicing architecture is considered ideal when industry verticals QoS requirements are considered for the dynamic creation, deletion, and modification of slices [1]. A network slicing model that is considered optimal must consider QoS and build network slices whose performance matches QoS profiles of the different verticals, which improves Quality of Experience (QoE) [1].…”

A network slicing model that is considered optimal must consider QoS and build network slices whose performance matches QoS profiles of the different verticals, which improves Quality of Experience (QoE) [1]. Our research work studies network slicing in 5G and proposes a network slice selection mechanism that builds network slices dynamically based on QoS requirements presented by applications in different verticals.…”

“…Optimal slicing in a dynamic manner is still limited by the various techniques isolated focus, limited templating rule base, short-sighted node placement strategies, limited routing approaches, limited orchestration capabilities, limited slice maintenance and limited controller logic. There is still significant interest and research opportunity for 5G and virtualized next generation networks, in particular for QoS-based slice selection [1]. To ensure that these virtual networks (slices) deliver the required QoS performance, our work seeks to solve this problem through a QoS-based slice selection model that is dynamic.…”
