Security: Enabling the Reliability of IP Telephony
By Dr. François Cosquer

Alcatel-Lucent Enterprise Business Group
Voice communication is a critical business application. In the past, telephony benefited from a dedicated, highly reliable infrastructure. When migrating voice communications to IP, the prime concern is how reliable the service will be, both in terms of Quality of Service (QoS), for example SLA metrics, but also in terms of Quality of Experience (QoE) as perceived by users. Issues such as performance, availability and confidentiality that are often taken for granted in the conventional TDM PBX world need to be assessed in the converged IP environment. The reliability of IP telephony – not only dropped calls, delay and audio quality but also service outage, downtime and availability – is a factor of the network design architecture, expected traffic load and the many components of the IP infrastructure involved in delivering the service. Security is one of these components, but is often perceived as simply a suite of threat mitigation features or systems against malicious attacks and mis-configurations. The talk will discuss how security must play a broader role in enabling the reliability of IP Telephony.

Workshop “Metabolism and mathematical models: Two for a tango” – 2nd Edition
Title: Workshop Metabolism and mathematical models: Two for a tango – 2nd Edition
Dates: October 25-26, 2022
Location: This workshop will be held in a virtual way
The topic of this workshop is metabolism in general, with a special focus, although not exclusive, on parasitology. Besides an exploration of the biological, biochemical and biomedical aspects, the workshop will also aim at presenting some of the mathematical modelling, algorithmic theory and software development that have become crucial to explore such aspects.
This workshop is being organised in the context of two projects, both with the Inria European Team Erable. One of the projects involves a partnership with the University of São Paulo (USP), in São Paulo, Brazil, more specifically the Institute of Mathematics and Statistics (IME) and the Institute of Biomedical Sciences – Inria Associated Team Capoeira – and the other involves the Inesc-ID/IST in Portugal, ETH in Zürich and EMBL in Heidelberg – H2020 Twinning Project Olissipo.
The workshop is open to all members of these two projects but also, importantly, to the community in general.
