  3. Today's Session Agenda • Introduction:Status, Technology, Targets • Use and Benefits vs. http • Models, Migration and Implementation • Solutions, Aspects and Prospects • Discussion Boosting Web Communication with WebSockets

  4. Introduction The Web becomes more and more Necessity of evolution to a platform for real-time data exchange WebSocket technology is the fundament pervasive interactive social mobile Boosting Web Communication with WebSockets

  5. 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

  6. WebSockets – Technology What are WebSockets? • Bidirectional, full-duplex, permanent TCP connections 4oo times less overhead⅓ of latency • Standardized in HTML5 by W3C and IETF protects investments • Single TCP port saves 50% server resources Boosting Web Communication with WebSockets

  7. WebSockets – Technology What else? • Designed for interactiveWeb Applications • Open for all kind ofstationary and mobilebrowser based and native apps • Not just a protocol, but a new paradigmRequest/Response Real-Time Comm. Boosting Web Communication with WebSockets

  8. WebSockets – Targets Demand from Developers, Providers and Users • CompatibilityInteroperability • IndependencyIntegratability • ReliabilitySecurity Boosting Web Communication with WebSockets

  9. WebSockets – Targets Demand from Developers, Providers and Users • AvailabilityScalability • ExtendabilityFlexibility • SimplicityMaintainability Boosting Web Communication with WebSockets

  10. WebSockets – Concept The Concept • Framework vs. Client/Server • 3rd Party Engines and Servers • Message Routing, Stream, Send, Broadcast, Events, Channels • Tokens and Plug-ins • Listeners and Apps • Filters and Encryption Boosting Web Communication with WebSockets
