Subject: [OASIS Issue Tracker] Updated: (MQTT-23) Should Message Identifier be called as Packet Identifier
[ http://tools.oasis-open.org/issues/browse/MQTT-23?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Rahul Gupta updated MQTT-23:
----------------------------
Description:
As Part of issue MQTT-17, it was proposed and agreed to use term "MQTT Control Packet" consistently and not "MQTT Command Message" in the specification.
However this change causes a problem in understanding of another term "message Identifier". Comments and discussion may be needed on the use of word Message Identifier and if it should be called as Packet Identifier. I am opening this JIRA issue for further discussion in TC calls.
example - from WD-04, line 383 - 385
"A non zero message identifier (MessageId) MUST be present in the variable header of the following MQTT command messages: PUBLISH(where Qos!=0), PUBACK, PUBREC, PUBREL, PUBCOMP, SUBSCRIBE, SUBACK, UNSUBSCRIBE, UNSUBACK "
In WD-05
"A non zero message identifier (MessageId) MUST be present in the variable header of the following MQTT Control Packets: PUBLISH(where Qos!=0), PUBACK, PUBREC, PUBREL, PUBCOMP, SUBSCRIBE, SUBACK, UNSUBSCRIBE, UNSUBACK "
Should message Identifier be called as Packet Identifier ?
