Session teaser

The current Internet protocols are inadequate to deal with situations in which substantial network delays are experienced. Initially thought for interplanetary communication, the delay-tolerant network (DTN) has interesting applications also on our planet.

The session will include information about the principles of the protocol, examples of applications, and the policy implications.

Session description

This session features a panel of experts who will address different aspects related to the Delay-Tolerant Network technology and applications. These are the points that we would like to cover:

What is the Delay-Tolerant Network (DTN) protocol and what are the problems that it addresses? Vint Cerf will present the bundle protocol and describe how it can be used in situations where there are substantial delays in the transmission and/or a large fault rate.

The Interplanetary Internet Communication in outer space experiences substantial delays and high risk of faults. Under these circumstances the current Internet protocols would be inadequate, while DTN will solve these problems. The Inter-Planetary Networking Special Interest Group (IPNSIG) was created for this purpose. Oscar García will present the work of IPNSIG.

Provide connectivity to the Sámi nomadic community The idea to make use of DTN for Sámi reindeer herding communities started twenty years ago within a university led constellation, with the basic notion of connectivity as such and focus on general services. Today a community initiative owns the process and the current focus is business intelligence. Maria Udén and Samo Grasic will present the evolution from 2003 to 2021.

Environmental monitoring and tourist protection in the Postojna caves In the Postojna caves there are several meteorological stations and other surveillance equipment that must provide the collected data to the base station. Boštjan Grašič will explain how DTN technology was used to vehicle the data to the base station via the tourist train that runs regularly in the caves.


Attendees are strongly encouraged to read the material referenced below under "Further reading" to have a better idea of the topics that will be discussed. During the session, the audience will be asked some questions via MentiMeter.

Format

The session will be organised as a round table. Four experts will provide short presentations of different aspects of Delay-Tolerant Networks. The interaction with the participants will be ensured by asking questions to the audience and providing also time for questions by them to the panelists.

Further reading

These excellent - and short! - videos explain the principle of DTN and its advantage over plain IP:

Key Participants

Key Participants are experts willing to provide their knowledge during a session – not necessarily on stage. Key Participants should contribute to the session planning process and keep statements short and punchy during the session. They will be selected and assigned by the Org Team, ensuring a stakeholder balanced dialogue also considering gender and geographical balance. Please provide short CV’s of the Key Participants involved in your session at the Wiki or link to another source.

Moderator

The moderator is the facilitator of the session at the event. Moderators are responsible for including the audience and encouraging a lively interaction among all session attendants. Please make sure the moderator takes a neutral role and can balance between all speakers. Please provide short CV of the moderator of your session at the Wiki or link to another source.

Remote Moderator

Trained remote moderators will be assigned on the spot by the EuroDIG secretariat to each session.

Reporter

The Reporter takes notes during the session and formulates 3 (max. 5) bullet points at the end of each session that:

  • are summarised on a slide and presented to the audience at the end of each session
  • relate to the particular session and to European Internet governance policy
  • are forward looking and propose goals and activities that can be initiated after EuroDIG (recommendations)
  • are in (rough) consensus with the audience

Current discussion, conference calls, schedules and minutes
