Communicate
beyond frontiers
It's no coincidence DTN is in our name. We're your people for Delay- and Disruption-tolerant Networking.
Built for links that come and go
DTN nodes can store data and forward it when the next connection becomes available, enabling scalable and resilient communication even when there is no continuous end-to-end path.
Disruption stops being a failure and becomes part of the design.

Your network.Your requirements.Your DTN solution.
Keep what works. We adapt DTN to your existing systems and requirements, not the other way around.
DTN engineering
from concept to operation
We research and develop network architectures, protocols, and software, with a focus on DTN and challenged networks. New concepts are prototyped, tested, and validated for real-world use.
We design solutions for your specific challenges and integrate them seamlessly into your environment. We can work with your existing stack, build on our own software, or develop the components you need from scratch.
We provide expert guidance on DTN and conventional networking, from architecture decisions and system reviews, to optimization and troubleshooting. We also offer ongoing maintenance and dedicated technical support.
Production-ready DTN
you can depend on
When you move from exploring to depending on DTN, we stand behind it – with guarantees, support, and platforms tailored to how you operate.
Enterprise StackA maintained, production-ready DTN stack for organizations that want to deploy our established software without a custom development project. D3TN-ES combines stable releases with defined support and SLAs.
Enterprise PlatformFor organizations that need DTN tailored to their environment. We design, adapt, and integrate the required DTN components into your system and provide hands-on support throughout its operation.
DTN in action
across space, sea, and beyond
The DARKSOL project explores how containerized workloads can be operated on satellites, landers, space probes, and other remote systems where conventional IP networking falls short. As part of the team, we investigate how to extend cloud-native execution environments with DTN capabilities so they remain usable in space despite intermittent and delayed connectivity.

The MISSION project aims to combine state-of-the-art space technology with proven techniques from the field of theoretical computer science to optimize the reliability and effectiveness of future space missions. As an industry partner in MISSION, we contributed practical expertise in delay-tolerant space networking and integrated, as well as validated, our protocol stack with state-of-the-art model-based approaches.

In this project, we explored how principles from the Recursive Internetwork Architecture (RINA) could be applied to DTN. We developed a recursive DTN approach using Bundle-in-Bundle Encapsulation and validated it in a field test combining terrestrial ad-hoc links with deterministic satellite links in collaboration with ESA's OPS-SAT team. The resulting system enabled resilient remote drone control over disrupted links without relying on real-time connectivity.

We initiated the COLDSUN project to connect underwater sensor networks to the Internet through satellite links. We developed and field-tested a relay buoy that collects and buffers sensor data until a satellite connection becomes available, using open-source software and commercial off-the-shelf hardware.

Yours to read, run, and build on
µD3TN and picoD3TN are our open-source implementations of the Bundle Protocol, designed for different platforms and resource constraints.
µD3TN is our lightweight Bundle Protocol v6 and v7 implementation in C. It integrates into existing systems over standard sockets and is designed for resource-constrained and challenged networks. Maintained since 2014, it is available to use, inspect, and adapt as the foundation for your own DTN system.
picoD3TN brings Bundle Protocol v7 to highly constrained hardware. Written in Rust and compatible with µD3TN, it can run directly on microcontrollers without an underlying operating system while retaining Rust's memory-safety advantages.
