XMPP-based Push Solutions - This document discusses using the XMPP protocol for push notifications. It provides examples of using ProcessOne Push Platform (P1PP) to enable use cases like pushing messages to Nabaztag rabbits or publishing blog posts. P1PP is a generic platform that can manage push notifications for users in a standardized way, and supports mobile, web, and desktop clients through XMPP and HTTP. It includes Javascript and command-line libraries for interacting with P1PP.

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

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

Messages are pushed
when needed
Posting blog post on web server
(triggers a hub "ping")

6. Enabling all those cases with ProcessOne
Push 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.
