JCSA24, pushing the Internet envelope

Every year, Afnic’s Scientific Council holds the JCSA, a day of lectures, free of charge and open to the public, which combines looking into the future with practical applications for here and now. For the 2024 edition, six guest speakers, researchers and experts, presented the results of their projects on the subject of “Pushing the Internet Envelope”. Ranging from DNS frugality and resilience to Internet communication under water and in space, the presentations expanded both the breadth of reflection and the scope of implementation. The replays of the presentations are now available.

On 4 October 2024, Afnic, the association responsible for the .fr TLD, and its Scientific Council, composed of 11 members from academia and manufacturing, held the annual Afnic Scientific Council Open Day (JCSA, for Journée du Conseil Scientifique de l’Afnic).

Broadcast live from the Cyber Campus in La Défense, this event brought together 90 participants for a discussion of this year’s subject: “Pushing the Internet Envelope.” Towards a faster, more remote, more intermittent, more political, more energy-efficient Internet” – there were many different views.

Presentation by Catherine LETONDAL, ENAC

Frugality and Resilience

Catherine Letondal, from the ENAC (National School of Civil Aviation), opened the day’s proceedings with a presentation of the work done on making the Internet at once more energy-efficient and more resilient.

Problems of energy proportionality on the Internet: when more means worse

The Internet’s energy footprint continues to increase, but does not vary with the network load. In this presentation, Romain JACOB gives some examples of ISP under-utilisation and goes on to present some pointers to improvement.

Presentation of Hugues FAVIN-LÉVÊQUE, Constellation.global

Universal access to broadband: Technological and geopolitical issues of mega-constellations of satellites

Constellations of satellites in low Earth orbit have demonstrated the feasibility of providing broadband access anywhere in the world. Hugues FAVIN-LÉVÊQUE sets out the conditions for providing such a satellite-based connectivity service and the associated difficulties.

Limits of the Internet from the geopolitical point of view

Louis PÉTINIAUD presented us with a picture of the many recent political processes that have fundamentally transformed the structure of the Internet and how they contribute to imposing more and more limits, not to say barriers, on the worldwide web.

Presentation by Benoît PARREIN, Nantes University, CNRS LS2N

Towards the Internet of Underwater Things

Benoît PARREIN tells us about the recent advances in the development of an Internet protocol (IP) adaptation layer for underwater acoustic sensors (UASN) based on the SCHC protocol. He also discussed the difficulties involved in communicating underwater and maintaining a network in such an extreme environment.

Presentation by Marc BLANCHET, Viagenie

The Internet protocol suite in space

Marc BLANCHET spoke about the development of IP applications for space and how the “Deep Space” initiative is adapting the Internet protocol suite for remote space communication despite the challenges of delays and interruptions.

Afnic thanks its Scientific Council warmly for this fine programme, the guest speakers for the quality of their presentations and the participants, both in person and remote. Thanks to all for this very high quality day in which much knowledge was shared and many ideas sown to think about and research for the preparation of tomorrow’s Internet!

See you all next year for the next edition of the JCSA!
