Keynote 1 – Truly autonomous networking: an MNO's perspective

9:00 - 10:00 am

Pierre Imai, Rakuten, Japan

Session Chair: Christian Jacquenet, Orange Labs, France


The concept of autonomous networks is quickly gaining traction in the telecommunications industry. Somewhat unusually, this trend is not so much driven by the suppliers as it is by the operators themselves. For it is us, operators who desperately need autonomous networks. In this talk, I will present why we, as a fully cloud-native MNO, require self-configuring, self-maintaining, self-optimizing, even self-evolving networks not in the far future, but now. I will first introduce the challenges we are facing and why traditional management approaches are insufficient to overcome them. Next, I will focus on what an autonomous network has to provide to address our needs and then, I will outline what open research questions need to be addressed before we even have a chance to ease the ever-increasing pressure we are being subjected to.


Dr. Pierre Imai is Head of the Research & Innovation Department at Rakuten Mobile, Inc. and has been working for the Rakuten Institute of Technology as Principal Scientist since 2016. His research and work experience includes the fields of networking & telecommunications, self-optimizing & autonomous systems, internet-scale distributed systems, artificial intelligence & machine learning, and robotics. Before joining Rakuten, he was improving the content distribution and active network monitoring systems down to network protocol level at Google, working on future internet and telecommunications research at NEC Labs Europe, and participated in multiple EU and national research projects such as ANA and Onelab. He is especially interested in building systems that can learn and improve themselves, for example, a network stack that autonomously re-composes and re-configures itself to reach close-to-optimal performance based on the current state of the network and traffic — as he did for his PhD, on a research grant from the Swiss National Fund.

Keynote 2 – AI-Based Cyber Defence: Two sides of the medal

13:45 - 14:45 pm

Gabi Dreo Rodosek, Research Institute CODE, Germany

Session Chair: Olivier Festor, University of Lorraine, France


The complexity of the IT environments is increasingly with tremendous speed. Managing such complex IT environments in only possible with embracing the power of AI/ML approaches. For example, the processing of huge amounts of events and their prioritization are application areas for AI-based approaches. However, AI/ML can be used for both sides, either negative or positive and can be seen as two sides of the same medal. On one side the advantages of AI applications are enormous and can revolutionize any professional sector. On the other side using AI/ML is making easier for cyber criminals to penetrate systems. It is a race between attack and defence, and a clear asymmetry between the attacker and defender. The attacker needs to search only for one vulnerability whereas the defender needs to defend the whole systems with all vulnerabilities that he even does not know. The talk will first introduce the problem area we are facing today in the cybersecurity resp. security management area. Next, the potential of AI/ML approaches for cyber defence will be introduced. The talk will especially identify the research questions and areas that need to be approached as well as the challenges to face such as building trustworthy datasets for deep learning. Embracing the power of AI also gives a new push for developing self-*management approaches. A view on this topic will be given as well.


Prof. Dr. Gabi Dreo Rodosek is the Executive Director of the Research Institute CODE (Cyber Defence), holds a Chair for Communication Systems and Network Security at the Bundeswehr University Munich, is the coordinator of the EU H2020 project CONCORDIA and has several supervisory and advisory mandates of various companies such as Giesecke+Devrient GmbH, BWI GmbH and Siltronic AG.

Keynote 3 – The Road to Aware-Nets

13:45 - 14:45 pm

Diego R. Lopez, Telefonica I+D, Spain

Session Chair: Laurent Ciavaglia, Nokia Bell Labs, France


While the introduction of closed-loop mechanisms is not such a radical change in network management, the use of data-driven techniques (analytics, AI…) will bring new ways of deriving further insights from behavioral data and improving network operation and management (OAM), and work to increase network self-awareness. The most delicate aspects to make data-driven network management a reality are not related to the analytics algorithms or AI models being applied, but with matters related to the network itself, and in particular:

  • How the data and action flows are built and applied
  • How the smart modules are placed and connected
  • The trustworthiness of data sources and processors
  • The interactions among humans and these smart modules


Dr Diego R. Lopez joined Telefonica I+D in 2011 as a Senior Technology Expert and is currently in charge of the Technology Exploration activities within the GCTIO Unit. Before joining Telefónica he spent some years in the academic sector, dedicated to research on network services, and was appointed member of the High-Level Expert Group on Scientific Data Infrastructures by the European Commission.

Diego is currently focused on applied research in network infrastructures, with a special emphasis on virtualization, data-driven management, new architectures, and security. Diego chairs the ETSI ISG on Permissioned Distributed Ledgers and the Network Operator Council ETSI ISG on Network Function Virtualization.

Apart from this, Diego is a more than acceptable Iberian ham carver, and extremely fond of seeking and enjoying comics, and good discussions on any (in)appropriate matter.

Keynote 4 – Practical Edge Computing for Mobile X Reality

9:00 - 10:00 pm

Pan Hui, HKUST, Hong Kong and University of Helsinki, Finland

Session Chair: Toufik Ahmed, Bordeaux INP, France


Smartphone is now a necessity of people's daily life, and we are enjoying various services on it with numerous mobile applications. However, the resource and communication limitations of a single mobile device make it insufficient in satisfying the real-time and interactive constraints of some computation intensive applications, such as mobile Augmented Reality (AR) and mobile Virtual Reality (VR). To bridge the gap, we utilize the processing power of edge servers via task offloading and build practical mobile systems which significantly outperforms state-of-the-art mobile systems in terms of latency, scalability, quality of experience (QoE), and many other aspects.artphone is now a necessity of people's daily life, and we are enjoying various services on it with numerous mobile applications. However, the resource and communication limitations of a single mobile device make it insufficient in satisfying the real-time and interactive constraints of some computation intensive applications, such as mobile Augmented Reality (AR) and mobile Virtual Reality (VR). To bridge the gap, we utilize the processing power of edge servers via task offloading and build practical mobile systems which significantly outperforms state-of-the-art mobile systems in terms of latency, scalability, quality of experience (QoE), and many other aspects.

In the case of mobile Augmented Reality, large-scale object recognition is an essential but time-consuming task. To offload the object recognition task and enhance the system performance, we explore how the GPU and the multi-core architecture on the edge servers would accelerate the large-scale object recognition process. With the carefully designed offloading pipeline and edge acceleration, we are able to finish the whole AR pipeline within one camera frame interval while maintaining high recognition accuracy with large-scale datasets. In the case of mobile Virtual Reality, existing 360-degree video streaming systems are suffering from insufficient pixel density, as the video resolution falling within the user's field of view (FoV) is relatively low. We utilize the edge server for ultra-high resolution video transcoding and implement a system which streams tile-based viewport adaptive 360-degree videos onto the mobile client. With this edge proxy, we successfully achieve 16K 360 degree video streaming onto off-the-shelf smartphones, achieving high frame quality and fluent playback without overwhelming the processing capacity of the smartphones.
