Orquestração dinâmica total de fatiamento de rede no núcleo 5G sobre plataforma nativa de computação em nuvem
Abstract
Technological advances in the fifth-generation (5G) mobile networks are based on native cloud computing platforms and Kubernetes has emerged as the orchestration system for virtualized infrastructure. However, these platforms were not designed to natively support 5G services. To illustrate, Kubernetes is designed to be agnostic to the services which orchestrates and is not able to dynamically reconfigure the 5G core according to existing network resources, i.e., it provides a partial dynamic orchestration to perform network slicing. This paper proposes a solution integrated with Kubernetes to allow full dynamic orchestration of network slicing at runtime, adjusting the 5G core. This integration is accomplished through a Kubernetes-integrated controller and a proxy for control plane. The controller adjusts the 5G core and adapts the virtualized infrastructure, while the proxy creates an abstraction for the control communication between access and transport networks with the core. The experimental results showed a reconfiguration total dynamic orchestration without interruption of the services, reducing the total reconfiguration requests number by network slices by 47.5%.
