Status update for WG dtn

A productive meeting was held on July 18th at IETF96 Berlin, with presentations on the status of BPBis, TCP-CL, BPSec, and numeric node ids.  There were also two presentations on potential approaches to solve the charter item of static routing in DTNs.  The BPbis presentation covered changes to the latest draft, particularly around the use of CBOR encoding and clarification of Customdy Transfer, with general consensus that the CBOR encoding should be specified as the standard bundle representation, and that convergence layer requirements should be stated in the draft, but specific details left to transport-specific drafts, for example TCP-CL. The TCP-CL presentation covered changes to the existing TCP-CLv3 experimental draft to align it with the latest BPbis work, and meeting consensus suggested it as a working group document, as it is a charter item.  The rest of the meeting involved several presentations concerning addressing and forwarding of bundles through a heterogenous DTN, and although the discussion was productive, no consensus on a way forward was noted.

A well attended interim meeting was held on September 28th, via WebEx, with presentations and discussion on the progress of BPbis and TCPCL.  Scott Burleigh reported that good progress was being made with the CBOR encoding.  Brian Sipos reported on the work on TCP-CL, and valuable discussion was had around backwards compatibility and hop-by-hop encryption using TLS.  Consensus from the meeting was that TCP-CL should be accepted as a WG document, if there was consensus on the mailing list, which there was after the meeting.

Minutes of both meetings are available on the DTN datatracker.
