=============================
ION development is managed by the Jet Propulsion Lab.
The Interplanetary Overlay Network (ION) software distribution implements Delay-Tolerant Networking (DTN) architecture, as described in Internet RFC 9171. It is designed for use in embedded environments, including spacecraft flight computers and ground systems.
Features
- Implementations of version 7 of Bundle Protocol.
- Bundle Streaming Service, for streaming audio, video, and telemetry over DTN.
- An implementation of BPSec, the new security protocol for BP, soon to be an Internet standard.
- Delay-Tolerant Payload Conditioning, for "transport"-like functionality over BP, plus application data aggregation and elision.
- An updated implementation of LTP link service based on erasure coding.
- An implementation of Class 1 CCSDS File Delivery Protocol (CFDP)
- An implementation of Asynchronous Management Protocol, for delay-tolerant network management.
- A delay-tolerant public key infrastructure, DTKA, based on a new Trusted Collective system.

The position "route ->toNodeNbr=contact ->toNode; route ->fromTime=contact ->fromTime;" in line 1166 and 1167 of "H:\ION package\ion-open-source-4.1.1\bpv6\cgr\libcgr.c" , I think we should change "route" to "newRoute" here. If the author sees it, can you pay attention.Reply from ION-DTN (Archived)Posted 2023-09-27
Thank you for the suggestion. We will look into it. If you can, please provide more context information regarding why you recommend such change. -
An excellent project. Is easy to adapt to specific network/link interfaces. And I have found no project that can compeet on features.
