[Sis-dtn] SIS-DTN Telecon Notes 20210630

[Dr. Keith L Scott]

SIS-DTN Telecon



BPsec -- Ed asked SEA-SEC for a quick review of format from the old SBSP book



LTP Orange

• Discussion

• Implementation

• Use cases?



BPv7

Felix Flentge

DTPC

• How to separate the various parts out of that

• Custody signaling in BPv7

• Stuff not covered in BIBE-CT -- want to use CT for multi-hop custody.

• Bundle might take a long time to get to their destination.

• independent custody signaling (based on ACS)

• Interested in a custody transfer mechanism where you don’t need to know/identify the next custodian

• Looking at very high data rate downlink scenarios / less predictable



Beau Blanding -- will be doing the writing, helped by Josh and Lee Pitts.



Maybe keep w/ BIBE-CT for now in CCSDS and augment with some other extension-block-supported mechanism later in CCSDS and/or IETF.



Convergence Layers for v7:

• LTP

• Encapsulation Packets

• Felix: Space packets

Simon Singh

Flow management

• Resource allocation / management in intermediate nodes

• Anybody else interested in flow management?



Extension blocks (previous hop, bundle age)

• Any node should be able to process these blocks

• Block processing flags



Actions:

• Look at the Orange thread

• NASA need for custody transfer?  PACE / Gateway

• Felix: write down thoughts on extension-block based custody transfer support

• Keith: figure out about APID assignment for BP over space packets

• Keith: definitive lists of capabilities for LTP and BP updates

• Understand the ‘traffic pared’ bundle expiration reason code

• What’s the purpose / use case?

• How does a node know that it’s neighbor isn’t just going to delete things?
