Two-day retreat in Meißen with the whole D3TN team
Last week on Monday and Tuesday we had our first retreat in the lovely town Meißen near Dresden! Apart from our usual crew from Germany we were very happy to also welcome our team members from D3TN US, Juan and Scott. On the first day of our retreat, everybody gave a presentation about a topic related to our company or Delay Tolerant Networks in general – for example we’ve discussed scientific research concerning Machine Learning in DTNs or Underwater DTNs.

µD3TN interoperability testing report
Our partner Spatiam Corporation has performed a series of interoperability tests between the ION (Interplanetary Overlay Network) and µD3TN Bundle Protocol version 7 implementations. Overall, the test results show that ION and µD3TN plus several tools shipped with the two implementations can be successfully used together. We would like to thank Spatiam for carrying out these extensive tests. Their detailed report is definitely worth a read!

D3TN´s field-tests presented in IEEE Communications Magazine
In their IEEE Communications Magazine, the Institute of Electrical and Electronics Engineers (IEEE) provides information on all aspects of communications. In April 2022, they published an article, written by us, about our concept of ring road networks (RRN), in which the functionality of delay-tolerant networking (DTN) and RRNs is being explained in detail and in an easily comprehensible way. The main issue that we´d wish to overcome with our technology is the fact, that there are still several billion people without reliable Internet access.

D3TN joins the first MISSION workshop
Being one of the industry partners in MISSION, D3TN participated in the project’s first in-person workshop at INVAP SE, San Carlos de Bariloche, Argentina. During the workshop and the surrounding weeks, while working in close collaboration with the project partners, we had (and will further pursue) numerous productive discussions and were able to explore new potentials for cooperation. We kindly thank the organizers, speakers, and our partners in the MISSION project for this perfect workshop and hope for the upcoming MISSION activities to be as successful and exciting!

More successful OPS-SAT experiments in space
After our previous tests at the end of 2020 featuring µD3TN instances on earth and one instance running on ESA’s OPS-SAT in space, we were lucky to conduct more tests over the course of four exciting days. Here is what we did: We firstly performed a “ping-pong” message exchange between a single terrestrial µD3TN instance and the one running on the OPS-SAT. After verifying that the basic scenario went smooth, we slowly introduced more and more complexity to cover more realistic use cases.

D3TN Inno Challenge
In May 2021, D3TN is offering attractive prizes for students who submit the most innovative application ideas for Delay- and Disruption-tolerant Networking (DTN) technologies. Prizes include tickets and speaker slots for the 2021 Space-Terrestrial Internetworking workshop, hoodies, as well as 1000 € for the winning team of 1-2 students. Interested? See our D3TN Inno Challenge Slide Deck for details.

D3TN contributes to Deploy with GAIA-X
GAIA-X and D3TN have a lot of core values in common. We, too, think that digital sovereignty is a goal worth to uphold and that its enabling factors like free and open source software (FOSS), open standards and open data are important. For the same reasons, we participate in groups like the Internet Engineering Task Force (IETF) or the InterPlanetary Networking Special Interest Group (IPNSIG) and publish our software such as µD3TN as FOSS.

µD3TN Ring Road experiment featured on ESA website
Our successful field test of µD3TN conducted on the OPS-SAT last Friday was just featured on the ESA website! A huge thanks to the ESA team and all supporters of this experiment. Stay tuned!

µD3TN space-tested
Less than one month after the initial release of µD3TN, we had the opportunity to run a field-test on board ESA’s OPS-SAT satellite during an overflight on 11 December 2020. As part of the test, we successfully transferred Bundles between the ground and space segment. A µD3TN instance in our infrastructure exchanged Bundles via the Internet with a µD3TN instance running on the OPS-SAT. The OPS-SAT link was provided by ESOC via an SSH connection and used µD3TN’s TCPSPP convergence layer adapter.
