Subject: [OASIS Issue Tracker] (MQTT-250) Merge the MQTT 3.1.1 and MQTT-SN 1.2 specifications
Allan Stockdill-Mander created MQTT-250: -------------------------------------------- Summary: Merge the MQTT 3.1.1 and MQTT-SN 1.2 specifications Key: MQTT-250 URL: https://issues.oasis-open.org/browse/MQTT-250 Project: OASIS Message Queuing Telemetry Transport (MQTT) TC Issue Type: Improvement Components: futures Reporter: Allan Stockdill-Mander Many features that have been discussed as desirable in MQTT, or assist with its mission to be a lightweight pub/sub messaging transport are available in MQTT-SN, along with it being a binding of a very similar protocol to MQTT on a connectionless transport. MQTT-SN provides the following on top of standard MQTT features; Negative ACKs on publishes and subscribes Server initiated pings Server initiated disconnects Ability to update will message data at any point Topic Registration saves space when sending/receiving on the same topic and allows subscription identification of non wildcard subs. Will as part of session data Client controlled timed expiry of session data (along with other features specifically aimed at sensor networks) A lot of the above are compelling for the current implementation of MQTT over a connected transport, and essential if MQTT is looking to extend its usefulness in mesh/sensor networks. -- This message was sent by Atlassian JIRA (v6.2.2#6258)
