Software 5G networks – understanding the 5G system

Chair: Dr. Eng. Marius Corici, Fraunhofer FOKUS, Germany 

In the last year a very large push was made towards the proper definition of the 5G system, complimenting the radio advancements while addressing the specific requirements coming from the verticals. This tutorial concentrates on the analysis of this evolution from the perspective of access network integration, connectivity support, slices and customization, application integration as well as how the integration with cloud and with SDN systems is coming to life as well as of the impact and resulting standard impact of the various use cases.

Even though networks are implemented as software since a very long time, the current paradigm change seems to have a similar impact as the all-IP networks once had for 4G. Because of this, the development perspective for the new systems has to adapt and to integrate the paradigms coming from the IT industry while being able to answer to the specific telecom requirements.
This tutorial will address the topic in a coherent manner across the different networking domains as reflected in the current advancements towards 5G networks. After setting down the impact of “everything is software" and the specific functional responsibilities towards the 5G software provider systems. A detailed impact on the different areas of the 5G system is provided including radio, edge, core, backhaul, management and application integration.

10.00 - 13.00 Tutorial 3

Understanding the Network Function Virtualization transformation based on practical experiences

Chairs: Giuseppe Carella, Michael Pauls, Fraunhofer FOKUS/TU Berlin, Germany
Billy Felton, Verizon, USA

With the evolution towards the 5th Generation of Mobile Networks, Software-based Networks are paving the way to the radical transformation of Network Operators' infrastructures. Moving from Hardware-based appliances towards Software-based artifacts requires a complete re-design of legacy network components. Virtualizing a Network Function using virtualization technologies can be easily achieved.
However, cloudifying (making it cloud-ready) a Network Function, providing modularity, scalability, etc., requires a re-design process. With the novel paradigm of everything as a software, Cloud Native approaches and Microservices architectural principles are influencing the way network functions are designed, developed and orchestrated across heterogeneous infrastructure resources. Virtualization as well as Cloudification of Network Functions is crucial for Next Generation Network Infrastructures.

Cloud-Native Network Functions requires a different kind of management system for being orchestrated. Having a common Management and Orchestration (MANO), as defined by the ETSI NFV, layer across different network operators’ Point of Presence  is crucial for having a single view of the infrastructure resources. Considering the increasing interest towards deployments at the Edge of the Network foreseen by the Multi-access Edge Computing and Fog Computing initiatives, requires flexible MANO systems for dynamically orchestrating resources. Legacy approaches are no longer suitable when moving towards virtualization. Novel technologies like OpenStack, representing one of the fundamental components in the Infrastructure as a Service domain, provides on-demand compute, storage and networking resources. However, those resources needs to be orchestrated in order to provide the required networking services. Last but not least, the always increasing momentum gained by containers technologies, like Docker and Kubernates, is paving the way to the so called Functions (or even processes) as a Service concepts. Executing functions when they are needed, provides innovative mechanisms for orchestrating resources.

This tutorial, will walk through those topics presented in a coherent manner. First of all, several use cases coming from the 5G and IoT domain will be presented. Network Slicing in 5G, Edge Computing, IoT, need to be analysed for addressing requirements at the infrastructure level. An overview about Cloud-Native applications principles and microservices approaches will be given. Those principles are the basis for building highly reliable network services in each of those use cases.

The tutorial continues moving towards the virtualization domain: a comparison between virtual machines (VMs) vs containers will be provided. In particular, the main focus will be on motivating the usage of VMs and containers for particular use cases. Technologies like Docker, Kubernetes, OpenStack will be presented and analysed.

One of the biggest part of the tutorial will be dedicated to the MANO domain, representing the crucial component in Next Generation Network Infrastructures. The requirements set by the presented use cases are crucial for understanding functionalities needed on this layer. The different components (Orchestrators, Managers) will be deeply discussed and analysed. An overview about the existing MANO technologies will be given: OpenSourceMANO, ONAP, Open Baton are just few examples implementing NFV MANO. A more detailed overview about Open Baton will be given. In particular, it will be highlighted its functionalities provided, and particular attention will be given to the design decisions which have driven its implementation. Its roadmap will be presented.  

The tutorial concludes with a hands-on session: bootstrap your virtualization environment in 5 minutes. People from the audience who would like to get started immediately, could make use of this session to bootstrap a NFV/MEC based environment on their own laptops.

In summary, the tutorial will cover the following topics:
  • Understanding the Network Virtualization transformation
  • Cloud-Native principles and microservices architectural approaches  
  • Virtualization technologies
  • Management and Orchestration for NFV and MEC
  • Open Baton as reference MANO framework
  • Bootstrap your virtualization environment in 5 minutes

Network Virtualization and Network Slicing for 5G Ready Networks

Chair: Giuseppe Carella, Fraunhofer FOKUS/TU Berlin, Germany

With the evolution towards the 5th Generation of Mobile Networks, Software-based Networks are paving the way to the radical transformation of Network Operators’ infrastructures. Network Function Virtualization (NFV) and Software Defined Network (SDN) technologies require a complete transformation of Network Operators’ infrastructures. Virtual Network Functions will be managed and orchestrated across heterogeneous and distributed datacenters.

On demand deployments of VNFs is foreseen as a way for lowering down CAPEX and OPEX. Management and Orchestration (MANO) tools are crucial for simplifying the way services are managed. The increasing usage of open source technologies in production networks is also paving the way to a new way of collaboration between network operators and VNF providers.

This half-day workshop focuses on providing innovative insights from the network operators perspectives towards transforming their network infrastructures for supporting Software-based Networks. The workshop addresses open issues and requirements which are currently faced by network operators while moving towards NFV-based infrastructures. Particular attention will be given to experiences gained in utilising open source technologies (OpenStack, Kubernetes, Docker, OPNFV, Open Baton, OSM, ONAP, etc) in their testbeds. Furthermore, the workshop will address particular use cases which are generated with the novel paradigm of End-to-End Network Slicing.
