Technical Summary
This specification extends the CoAP protocol (RFC 7252) with a pair of
"Block" options to enable the transport of large payloads through
multiple request-response pairs. In constrained environments, these
blockwise transfers have an advantage over fragmentation at lower layers
(e.g., IP), since the server can be truly stateless with no need for a
connection setup or other server-side memory of previous block
transfers. The specification is intended for standards-track, as it is a
widely implemented extension of a standards-track protocol.

Review and Consensus
The specification was developed along with the base CoAP specification
and received significant review by active WG members and implementers.
Two major discussions were had and resolved while finding consensus.
Several implementations of this final version have completed an
interoperability test event with a very good score. Further implementer
feedback also was positive.

Personnel
Matthias Kovatsch is the document shepherd.
Alexey Melnikov is the responsible Area Director.
