    Today's Session Boosting Web Communication with WebSockets 05.04.2011
    • The Web becomes more and more
        • Necessity of evolution to a platform for real-time data exchange
        • WebSocket technology is the fundament
    Boosting Web Communication with WebSockets 05.04.2011 Introduction pervasive interactive social mobile
  • Status of Web Communication
    • The HTTP Protocol
    • Designed for document transmission
    • Cumbersome, nearly real-time tricks
        • Polling, Long-Polling
        • Reverse-AJAX, Comet etc.
    • Ultimately non-standardized hacks
    • Remains a Request/Response mechanism
    Boosting Web Communication with WebSockets 05.04.2011
    • What are WebSockets?
    • Bidirectional, f ull-duplex, permanent TCP connections 400 times less overhead ⅓ of latency
    • Standardized in HTML5 by W3C & IETF protects investments
    • Single TCP port saves 50% server resources
    Boosting Web Communication with WebSockets 05.04.2011 WebSockets – Technology
    • What else?
      • Designed for interactive Web Applications
      • Open for all kind of stationary and mobile browser based and native apps
      • Not just a protocol, but a new paradigm Request/Response Real-Time Communication
