Abstract:
CoAP (RFC7252) is a RESTful transfer protocol for constrained nodes
and networks, originally using UDP or DTLS over UDP as its transport.
Basic CoAP messages work well for the small payloads we expect from
temperature sensors, light switches, and similar building-automation
devices. CoAP's Block protocol (draft-ietf-core-block) allows
transferring larger payloads over limited-size datagrams -- for
instance, for firmware updates.
CoAP over TCP and TLS (draft-ietf-core-tcp-tls) enables the use of
extended, but not unlimited, size messages. The present
specification, Block-wise transfers in CoAP: Extension for Reliable
Transport (BERT), extends the block protocol in a simple way to be
able to make use of these larger messages over a reliable transport.
