UWSIO: Towards automatic orchestration for the deployment of 5G monitoring services from bare metal

The next generation mobile networks 5G are currently being intensively developed and standardized globally, with commercial prototyping 5G connections already emerging. At the 5G system level, one of the Key Performance Indicators (KPIs) defining 5G is substantially reduced service creation time for 5G network operators and/or service providers to increase the system efficiency and thus reduce operational costs. In this work, we focus on realize this challenging KPI in terms of speedy creation of monitoring services for 5G operators from scratch (no operating system pre-installed). A new 5G infrastructure orchestrator UWSIO is proposed to achieve fully automated deployment of 5G monitoring services. The architecture of this orchestrator is presented, which is compliant with the ETSI MANO standard to deal with both physical and virtual resources towards establishing the services running over the infrastructure. The proposed orchestrator is implemented in a real-world testbed and the implementation details are provided. Experimental results demonstrate that the performance of the design and implementation of this orchestrator is able to meet the KPI requirement for 5G operators.
