Distribution of Svom VOEvents using the XMPP protocol

Le Fèvre, Jean-Paul

Svom is a French-Chinese space mission dedicated to GRB studies. Launch is due to take place in 2016. Data describing events detected by on board instruments as well as parameters coming from on ground processing will be formatted according to the VOEvent schema. And the Svom VOEvent packets will be broadcast in real time using the XMPP protocol.

A reference implementation has been developped to validate therchitecture and to figure out which performances can be reached by such a system. The prototype described in this presentation is written in Java and is based on the Ignite Realtime open source libraries : Openfire and Smack. The pubsub paradigm has been chosen to implement requirements related to Svom alert messages distribution policy.
