Blockwise transfers in CoAP
draft-ietf-core-block-04
C. Bormann, Z. Shelby
CoRE WG, IETF-81 Quebec City
Current Status
• Changes in -03
– Enabled block transfer in request and
response (BLOCK1, BLOCK2)
• Main use case is RPC using POST
• Changes in -04
– Editorial improvements
• -02 is implemented pretty widely
• -03 has a few implementations (BLOCK1)
Work Needed
• Re-write the draft!
• Better names for BLOCK1, BLOCK2?
– Haven’t found consensus yet on the names…
• Clarify that a 4.13 (Request Entity Too
Large)may mean either "truncated" or "do not
have resources for blockwise” [Esko Dijk]
