September, 2015: JoramMQ/MQTT scales up to 750.000 concurrent connections on a simple VM.

At the request of a user we conducted a study on the stability of JoramMQ / MQTT under stress conditions including a very high throughput of messages and an extremely large number of clients.

October 9 2014: PRESENTATION AT JFSMA14.

ScalAgent DT presents its technology at the 22nd JFSMA, a French conference on multi-agent systems at Loriol-sur-Drôme.

This presentation details the technological core of Joram: the distributed execution engine implements a reactor pattern, where agents communicate exclusively through events and react to events atomically. This technology enables ScalAgent‘s agents to interact effortlessly, be they located on the same system or on different ones.

It is at the core of several of our products, Joram or JoramMQ, the monitoring/control solutions developed for the CNES, or the mediation solution of TagSys RFID.

September 18, 2014: CNES workshop - Mobility for operations

The topic covers also cooperative missions which involve several agencies and other entities.

David Féliot will be there for ScalAgent D.T. to present the interest of the MQTT technology in this context, and the value of the MQTT implementation in JoramMQ Entreprise.

September, 2014: MQTT implementation on top of Joram.
