[Sis-dtn] Bundle Transfer Protocol - Unidirectional

[Jorge Amodio]

Good Morning,

As I expressed on the IETF DTN WG list, I'd very much like to see this moving forward since it fits one of the real use case scenarios today where we use astronomy dishes that only "listen"

Thanks & Regards
Jorge

Fyi

This is something Rick had already inform me and Bob some weeks ago when we did the monthly CCSDS/IETF alignment on DTN activities.

Regards,

Tomaso

Hi All,

Just to let you all know I have recently published a personal draft: Bundle Transfer Protocol - Unidirectional. https://datatracker.ietf.org/doc/draft-taylor-dtn-btpu/

The intent is to provide a minimal, efficient wire protocol for transferring Bundles over unidirectional, unreliable frame-based link-layer protocols, such as AOS, TM, 5G PDU and Ethernet.

I'm following it up with a related draft covering how to add FEC to BTPU, for cases when selective FEC is useful, and a simple BTPU-over-Ethernet draft, which might be handy in some scenarios.

Also, I would be particularly interested in collaborating with anyone who can help draft a good specification for BTPU over the CCSDS data-frame protocols.

I hope to find time in our packed WG agenda at IETF-112 to discuss it a bit more.

Many thanks,
Rick
