      Realtime Presentation Boosting Web Communication with WebSockets 05.04.2011
      • Agenda
        • Introduction: Status, Technology, Targets
        • Use and Benefits vs. http
        • Models, Migration and Implementation
        • Solutions, Aspects and Prospects
        • Discussion
      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
      Boosting Web Communication with WebSockets 05.04.2011 WebSockets – Technology
      • Demand from Developers, Providers and Users
        • Compatibility Interoperability
        • Independency Integratability
        • Reliability Security
      Boosting Web Communication with WebSockets 05.04.2011 WebSockets – Targets
      • Demand from Developers, Providers and Users
        • Availability Scalability
        • Extendability Flexibility
        • Simplicity Maintainability
      Boosting Web Communication with WebSockets 05.04.2011 WebSockets – Targets
      • The Concept
        • Framework vs. Client/Server
        • 3 rd Party Engines and Servers
        • Message Routing, Stream, Send, Broadcast, Events, Channels
        • Tokens and Plug-ins
        • Listeners and Apps
        • Filters and Encryption
