[mosquitto-dev] Multiplexed MQTT
|
Hi All, and Roger especially.
One function that is implemented (by Nick O'Leary, as it happens) in one
of the brokers in the RSMB repository is multiple MQTT sessions over one
TCP connection. This was used for an MQTT-SN gateway of the transparent
style. Transparent means that each MQTT-SN connection arriving at the
gateway results in another MQTT connection, but using MQTT multiplexed
over a single socket, resources are saved.
As I'm thinking about coding up an embedded MQTT-SN to MQTT gateway I
thought again how useful this could be. So how about in Mosquitto?
It's not in the MQTT standard, but that hasn't stopped us before, and
the standard can be driven by what people find useful.
This sort of multiplexing could also be used in bridges, so that you
could have an MQTT connection which hopped over multiple bridges before
getting to its final destination. I haven't thought that one through
though, but it sounds cool :-)
