  • 1. XMPP-based Push Solutions -pubsub.p1pp.netXMPP, HTTP and how to use ProcessOne PushPlatformFebruary 2012
  • 2. Violet use case: Nabaztag push architecture Initial architecture based on pure polling to check «inbox»Query to check inbox (every 5 seconds) Based on database and HTTP front servers Database with rabbits messages Broadcast HTTP Fronts service Data publication
  • 3. Violet use case: Nabaztag push architecture New push architecture on XMPP History of data Database storing the Lower latency and more reliable rabbits inbox delivery Persistant XMPP connection HTTP infrastructure could beMessages are pushed when needed broadcast halfed service ejabberd servers Publishing data
  • 4. Example: Gitlive This is our technological demo showing in browser, anonymous pubsub.
  • 5. Example: The Upik case Pubsubhubbub Hub for subscribers Could be the same hub XMPP servers Pubsubhubbub Persistant XMPP Hub connection for publisher Messages are pushed when needed Posting blog post on web server (triggers a hub "ping")
  • 6. Enabling all those cases with ProcessOnePush Platform (P1PP) Build a generic platform able to manage all those cases for our users in a standard way. Build a development community around realtime protocols. Share our XMPP pubsub expertise with developers around the world. Propose our ability to make XMPP Pubsub scale as a service. Support innovation around notification and new usage: Mobile. Web protocols: websockets.
