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

4 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 Introduction pervasiveinteractivesocialmobile

5 Status of Web Communication Boosting Web Communication with WebSockets 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

6 Boosting Web Communication with WebSockets WebSockets – Technology What are WebSockets? Bidirectional, full-duplex, permanent TCP connections 4oo times less overhead ⅓ of latency Standardized in HTML5 by W3C and IETF protects investments Single TCP port saves 50% server resources

7 Boosting Web Communication with WebSockets 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 Comm.
