Unofficial ION-DTN Experimental Site

This is a personal, unofficial site for learning about and experimenting with ION-DTN.

I hope this site can serve as a small starting point for those interested in ION-DTN and space communication technologies.

What is ION-DTN?

ION-DTN (Interplanetary Overlay Network - Delay/Disruption Tolerant Networking) is a DTN implementation designed to deliver data even in environments with significant delays and communication disruptions, such as space communications.

Relationship with LunaNet

LunaNet is a network architecture intended to support interoperable communications, navigation, and timing services on the lunar surface, in lunar orbit, and in cislunar space.

Lunar and deep-space communications cannot always assume a continuous end-to-end connection like the terrestrial Internet. This is where DTN becomes important: it is designed to store, forward, and deliver data even when links are delayed, interrupted, or only available at certain times.

This site does not build LunaNet itself. Instead, it uses ION-DTN as a practical way to learn the basic ideas behind delay- and disruption-tolerant communication used in space-network concepts.

For background information on LunaNet and lunar communication/navigation systems, please refer to the following official pages.

Meet IONES, the ion-dtn.net Mascot

ION-DTN.NET mascot character IONES
IONES

IONES is the mascot character of ion-dtn.net. Designed with a lunar-inspired ornament and a glowing DTN-themed outfit, she was created as a friendly guide for this site.

Her role is to make topics such as ION-DTN, LunaNet, and delay/disruption tolerant communication feel more approachable, while representing curiosity, resilience, and communication across distance.

  • Name: IONES
  • Role: Mascot and guide for ion-dtn.net
  • Motif: The Moon, space communications, cislunar space, and DTN
  • Personality: Calm, curious, friendly, and technically minded
  • Keyword: Store, Forward, and Connect.
