Intent-Based Real-Time 5G Cloud Service Provisioning

Software Defined Networking (SDN) and Network Function Virtualisation (NFV) have paved the way for programmability, flexibility and scalability of mobile networks. Both technologies offer significant advantages to the Network Operators (NOs) in terms of network management and service provisioning which widens their market to 3rd party providers such as Virtual Network Operators (VNOs) and Over-The-Top (OTT) Application Providers in domains such as Mobile BroadBand and Internet of Things (IoT). This paper, proposes an OTT Intent Based Network Framework for 5G Network Slice provisioning. The aim is to automate the task of network slicing through a declarative approach known as Intents while hiding network complexity from NOs, Mobile Infrastructure Tenants and VNOs. We provide an experimental validation of the Intent Framework with a scenario of a 5G IoT network slice deployment.
