    [ https://issues.oasis-open.org/browse/MQTT-604?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=83730#comment-83730 ] 

Davide Lenzarini commented on MQTT-604:
---------------------------------------

"The network must not deliver a datagram more than once."

> The section on "Networks and Transport Layers" needs to specify the requirements on the underlying transport, as MQTT 5.0 does in the normative statement:
> A Client or Server MUST support the use of one or more underlying transport protocols that provide an ordered, lossless, stream of bytes from the Client to Server and Server to Client [MQTT-4.2-1].
