Subject: [OASIS Issue Tracker] (MQTT-252) Support for large message transmission


    [ https://issues.oasis-open.org/browse/MQTT-252?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=62584#comment-62584 ] 

Mickael Remond commented on MQTT-252:
-------------------------------------

What about leveraging ICE, for this kind of need ? It would be using STUN / TURN proxy to transmit the large file. MQTT could just be used for "signalling"

> MQTT has an architected limit of 256MB for the message payload. In practice, transmitting a message this large is troublesome. First, the transmission of large messages ties up the network connection for a considerable time, potentially blocking smaller messages. Second, the longer a message takes to transmit, the higher the chance that a network outage will interrupt the transmission, which would then have to be restarted from the beginning. MQTT would make a good transport for delivery of large payloads, in particular device firmware, but only if they can be transmitted in a more manageable way.
