Subject: [OASIS Issue Tracker] (MQTT-552) Should a broker prohibit publish -1 messages from sleeping clients
[ https://issues.oasis-open.org/browse/MQTT-552?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Ian Craggs updated MQTT-552: ---------------------------- Proposal: Section 7.1 (underneath existing para) Sleeping clients are allowed to publish messages at QoS -1. > Should a broker prohibit publish -1 messages from sleeping clients > ------------------------------------------------------------------ > > Key: MQTT-552 > URL: https://issues.oasis-open.org/browse/MQTT-552 > Project: OASIS Message Queuing Telemetry Transport (MQTT) TC > Issue Type: Improvement > Components: MQTT-SN > Affects Versions: MQTT-SN-1.2 > Reporter: Simon Johnson > Assignee: Ian Craggs > Priority: Minor > Labels: Implementation-notes > > From the specification; > "..Because PUBLISH messages with QoS level -1 âcould be sent at any time by clients (even with no connection setup" > I took this to mean that there is no issue with a broker processing messages received at -1 from a sleeping client. Perhaps we could confirm this, and make clear in implementation notes precisely when -1 messaging is allowed. -- This message was sent by Atlassian Jira (v8.3.3#803004)
