Hi folks,

A slightly off-topic question -- though not too much, hopefully.

One of the LURK [0] proposals is draft-cairns-tls-session-key-interface [1].

In Section 7.1.2 [2] the authors propose to transport the LURK payloads over CBOR/CoAP (over DTLS/UDP, I guess).

Now, a single LURK box could have to handle lots of these requests, potentially in thousands per second, whereas CoAP's default congestion control algorithm parameters [3] are, by design, way too conservative to be suitable for high-throughput use cases.

Is there anyone that has played with CoAP for high-throughput applications who'd be willing to share his/her experience with the group and the wider IETF community?

Cheers, thanks very much,
t
