Keynote Talk I - September 20, 2022
Network Resilience: Stakes and Challenges
Bertrand Decocq (Orange, FR)
Abstract
In this talk, after detailed explanations of network outages we met within Orange networks, we will give some statistics, based on ENISA figures, of the main root causes and their impacts in terms of customers lost hours (number of hours-of-service interruption * number of customers impacted). Lessons have been learnt since these outages, a zoom on 5G standards improvement will be done to show the main mechanisms that could be deployed in future mobile networks. But our networks will have to face new challenges in the years to come: (i) network complexity with 5G and virtualization concept introduction, (ii) higher verticals/services requirements in terms of availability, latency or reliability, (iii) critical infrastructures interdependencies increase and (iv) climate changes adaptation. Network resilience design must still be addressed internally by each network operator, but it is not sufficient anymore. A close coordination with other stakeholders is required. This talk will end with some key questions that could be solved through operations research or artificial intelligence techniques.
Biography
Bertrand Decocq is working in Orange since 1997 after a PhD in Computer Science and Operations Research, and ENSIIE engineering school. Bertrand is team and project manager and is a member of Orange expert community on future networks. He started to work on mobile network resilience in 2014 and is now working with a chair of Centrale Supelec on "Risks and Resilience of Complex Systems" dealing mainly with interdependencies between critical infrastructures from resilience and maintenance perspectives. He is also in charge of a partnership with EDF R&D on cross resilience between energy and telecommunication networks.

Keynote Talk II - September 21, 2022
Impact of Software Availability on System Reliability
Carmen Mas-Machuca (Technical University of Munich, DE)
Abstract
The increasing importance of programmability for control and data planes of modern so-called softwarized communication networks together with the operators’ requirements to support open source software, demand for a new framework to model and evaluate the dependability of the software modules. Programmability in softwarized networks such as SDN controller or P4 switches, posing stringent requirements on the availability and continuity of the software processes. Moreover, the increasing use of open source software with a huge number of contributors makes it extremely difficult to control and assess the quality of the code. This talk gives an overview of the framework to evaluate the software availability and how this availability can be included in system dependability studies such as data centers.
