Re: [dtn] Draft DTNWG Charter Text

Hi Felix,

A pity you can't make it, but I think we all understand a busy schedule.

Perhaps an option might be to have a more generic charter item around "reliable bundle delivery" rather than explicitly naming custody transfer as the only solution?

Or does that result in a completely generic work item that we can never achieve in a reasonable time?

Cheers,

Rick

All,

sorry for the very short notice. I cannot attend today but would like to propose an additional work item:

* Efficient Bundle Status Reporting

I have had some background discussions on this with Scott and it is something ESA might like to use for High Data Rate Space-to-Earth Downlink where it could be used as an (better) alternative to custody transfer.
I plan to present the initial ideas later this week in the CCSDS DTN WG but I thought it would not harm to have it in the IETF charter as well (maybe even replacing the custody transfer for reliable bundle delivery).

Regards,
Felix
