Hi All,


Following the Core meeting at IETF 110 today,
https://datatracker.ietf.org/doc/draft-ietf-core-new-block/ which handles
sending a CoAP non-confirmable body split over multiple payloads, has passed
WGLC, and is waiting for the write-up to progress the document to the IESG.


This draft refers to
https://datatracker.ietf.org/doc/html/draft-bosh-dots-quick-blocks-01 for an
example mechanism to negotiate the additional congestion control parameters
using the DOTS signal channel configuration mechanism, defining some new
YANG/CBOR mapping entries.


This draft has been implemented, available using libcoap and the specific
code (not merged) can be found at https://github.com/obgm/libcoap/pull/611
and has been tested in lossy and DOTS environments.


This draft is of significance for the DOTS telemetry draft (
.3 ), which needs to be able to continue to send (large) telemetry
information under network attack situations.
