E2E Network Slice Management Framework for 5G Multi-tenant Networks
Chirivella-Perez, Enrique Chirivella,Salva-Garcia, Pablo,Sanchez-Navarro, Ignacio,Alcaraz-Calero, Jose,Wang, Qi 한국통신학회 2023 Journal of communications and networks Vol.25 No.3
Network slicing is one of the cornerstone featuresof the fifth generation (5G) networks to enable the multiplexingof virtualised logical networks over the same physical networkinfrastructure for various vertical business services. Architecturesbased on network slicing enable network operators to offer end-to-end (E2E) vertical services whilst assuring fulfilling tailoredservice level agreement (SLA) requirements. Despite the numer-ous benefits that this concept offers, the need for efficient, scalableand holistic E2E management of network slicing significantlycomplicates network operators’ network management and im-poses significant challenges in the quality of service (QoS). Thispaper proposes a novel intent-based slice manager frameworkover a service base 5G architecture that allows flexible definitionsto customise network slices, automates all essential managementtasks for 5G network slice providers, manages the life cycles ofall sorts of network slices, and guarantees their QoS in a unifiednetwork slice management framework. The proposed frameworkis empirically validated in a realistic large-scale 5G multi-tenantinfrastructure. The high scalability of the framework is basedon the empirical results supporting more than 512 physicalmachines, 534288 virtual machines and more than two millionnetwork interfaces.
