“The Message Queuing Telemetry Transport (MQTT) has been used by
IBM as a messaging protocol for a number of years. In 2010, IBM
announced that MQTT would be freely available under a royalty-free
license. Today IBM has expanded the openness by contributing an
open source MQTT client for Java and C to Eclipse.“MQTT runs on top of TCP/IP, it’s a simple API that sits on
top,” Andy Piper, WebSphere Messaging Community Lead at IBM told
InternetNews.com. “It doesn’t have any relationship with HTTP, it
doesn’t have any kind of encapsulation where it runs through a
tunnel, it’s not that kind of thing, it’s purely on top of the
TCP/IP networking stack.”
