Constrained Application Protocol (CoAP) Block-Wise Transfer Options Supporting Robust Transmission

Metadata

Publisher: IETF
Doc Type: Standard
Pages: 41
Abstract: This document specifies alternative Constrained Application Protocol (CoAP) block-wise transfer options: Q-Block1 and Q-Block2. These options are similar to, but distinct from, the CoAP Block1 and Block2 options defined in RFC 7959. The Q-Block1 and Q-Block2 options are not intended to replace the Block1 and Block2 options but rather have the goal of supporting Non-confirmable (NON) messages for large amounts of data with fewer packet interchanges. Also, the Q-Block1 and Q-Block2 options support faster recovery should any of the blocks get lost in transmission.
