Dynamic Service Parameter Negotiation in the 5G Era
Abstract: Network operators provide an ever-growing service portfolio. The diversity and the complexity of these services have been raising technical challenges for many years, not only during the service design phase but also during the service operation phase. The emergence of Software-Defined Networking (SDN) techniques has often been the opportunity to make debatable promises about their ability to facilitate the automation of service delivery procedures. Reality is much different. Process automation is often restricted to dynamic configuration tasks, whose steering relies upon decision-making procedures that remain “manually declarative”: the data that are used to feed the computation logic that will drive the execution of configuration tasks are statically declared. Automation is actually far more protean and relies upon a set of functions and control loops that interact in a deterministic and sometimes autonomic fashion. Dynamic service parameter exposure and negotiation is one of those functions that should greatly contribute to the fully automated delivery of services in (SDN-enabled) 5G environments. The talk will discuss an approach to such negotiation scheme, and pick the iconic example of Internet of Things (IoT) services to illustrate its benefits as well as foreseen challenges

Christian Jacquenet graduated from the Ecole Nationale Supérieure de Physique de Marseille, a French school of Engineers. He joined Orange in 1989, and he is currently the Referent Expert of the “Networks of the Future” Orange Expert community. Until recently, he was the Director of the Strategic Program Office for advanced IP networking within Orange Labs. He is also the head of Orange’s IPv6 Program that aims at defining and driving the enforcement of the Group’s IPv6 strategy. He conducts development activities in the areas of Software-Defined Networking (SDN), IP networking, automated service delivery procedures, including service function chaining techniques. He authored and co-authored several Internet standards in the areas of dynamic routing protocols and resource allocation techniques, as well as numerous papers and books in the areas of IP multicast, traffic engineering and automated IP service delivery techniques. He also holds several patents in the areas of advanced home and IP networking techniques.
Challenges in Validating 5G
Abstract: As the technologies that will be used in the 5G system become better known, it is becoming evident that validation of the system and its components will fundamentally change from the past. Testing NFV, SDN and MEC has deep impacts on the methodology used, while the reality of having 1000x the amount of connections in the system as a result of IoT brings in fresh new challenges. The massive small cell densification brought in by mmWave spectrum usage, and new system concepts such as the new service based architecture and network slicing also impact the metrics to be sought and measured when validating the design. The QoS metrics to be measured for new services offered are mostly known, but will have fear stricter constraints. This presentation will detail the impacts on test methodologies and architectures for 5G system validation. It will outline test plans and the environments to be used for such validation, as well as point towards industry activities that help the users work towards the goal of full system and component testing for the new 5G world.
