ejabberd implements version 0.13.0 of this specification, which is very close to the state-of-the-art implementation. The work is proposed in the experimental XEP-0369: Mediated Information eXchange (MIX). The XMPP Standard Foundation is working on a new specification to make implementing groupchat easier. To provide good groupchat support on mobile, you need to provide a way to bridge a presence-based model to a subscription-based model. This means trouble on mobile, as apps cannot typically run all the time. XMPP is a session-based, and Multi-User Chat is a presence-based protocol. The road to a better support for XMPP on mobile: MIX and MucSubįor a historical reason, groupchat on mobile using XMPP has been difficult in the past. Let’s see how ejabberd helps pushing modern XMPP to provide better mobile support. Implementing a Whatsapp-like mobile groupchat experience on top of XMPP is often a challenge. Like ejabberd XMPP components, our MQTT service is highly scalable and works in a cluster. This makes ejabberd a highly scalable alternative to existing MQTT servers, while still relying on the huge ejabberd ecosystem of extensions that have been developed over the years. You can use MQTT to write control applications in JavaScript, running in a web browser, connecting directly to ejabberd using MQTT over Websocket.You can use MQTT over Websocket on devices that will need to go through a HTTP proxy (they will need to be Websocket friendly, but this is more and more the case).This major new feature covers several use cases: With ejabberd 19.05, you can now develop MQTT clients that work over Websockets. Up to now, MQTT was only supported over raw TCP sockets and TLS. It supports MQTT 5.0, a specification that is more compact (binary protocol) and easier to parse for smaller devices.It is ideal on Raspberry devices, for example. It targets devices that are powerful enough to be handling XML parsing. It is typically used to provide a global identifier to a device ( which can be reached in a federated way. New Features and improvements MQTT over WebsocketĮjabberd supports the Internet of Things in many ways: We also have improved existing features, improved server performance and fixed several issues. The main focus of this release has been to expand our MQTT stack with Websocket support, to power web based IoT platforms.
