[Sis-dtn] Telecon 20250821

[Felix Flentge]

Hi,

We'll have a joint meeting on the Last-Hop/First-Hop services with at least some CSS people. As far as I know, nobody has really looked into the use of CSTS or service management service in  the context of DTN. We can use this meeting to check the current status but I wouldn't spent much time on it now (I believe it is an important topic but to progress someone needs to take it up - we may have some work on this upcoming and we could eventually present in spring).

For the Orange Books, we should have dedicated sessions (BP QoS, BP Custody & Compressed Reporting, BIBE) but we should schedule a slot to assess the overall status of projects / books.

Regards,
Felix

Hi Keith,

If I’m not wrong Simon had already a spreadsheet to track the situation of the different active books, which could be used as baseline to construct an agenda. Maybe Felix could start from that one.

Roughly one year ago we also had a meeting with the CSS area. We weren’t quite ready to have another round this year Spring. What about now? Erik hasn’t pinged me yet…

Last but not the least we should discuss (probably on Friday if time allows) what to do with all the orange books that I guess will be published at some point in 2026. Typically, though this not being a requirement, orange books pave the way towards blue ones…

Some desire to have a different administrative record type to distinguish different encapsulated BP version types.  Maybe an orange book?  Discussion in Hamburg.
