Invitation to comment on MQTT V5.0 - ends 14 January 2019

OASIS and the OASIS Message Queuing Telemetry Transport (MQTT) TC [1] are pleased to announce that MQTT Version 5.0 has been approved as a Candidate OASIS Standard (COS) [2]. The COS now enters a 60-day public review period in preparation for a member ballot to consider its approval as an OASIS Standard.

MQTT is a client/server publish/subscribe messaging transport protocol. It is lightweight, open, simple, and designed to be easy to implement. These characteristics make it ideal for use in many situations, including constrained environments such as for communication in Machine to Machine (M2M) and Internet of Things (IoT) contexts where a small code footprint is required and/or network bandwidth is at a premium.

The protocol runs over TCP/IP, or over other network protocols that provide ordered, lossless, bi-directional connections.

The TC received 4 Statements of Use from HiveMQ, IBM, the Eclipse Paho Project, and VerneMQ [3].

The candidate specification and related files are available here:
