  1. The End of Application Protocol Standardization (?) Jonathan Rosenberg Chief Technology Strategist, Skype

  2. Outline • Experiences and Lessons from SIP – the Telecoms Innovation Cycle • (Obvious) Industry Trends • The Internet Application Innovation Cycle and its Implications for IETF

  3. SIP for Beginners SIP Serverexample.com SIP Serverexample.org SIP SIP SIP RTP

  4. Example SIP Message INVITE sip:+17327654321@example.com SIP/2.0 From: J. Rosenberg <sip:+14082321122@example.com> ;tag=76ah Subject: Conference Call To: John Smith <sip:+17327654321@example.com> Via: SIP/2.0/UDP 1.2.3.4;branch=z9hG4bK74bf9 Call-ID: 1997234505.56.78@1.2.3.4 Content-type: application/sdp CSeq: 4711 INVITE Content-Length: 187 v=0 o=user1 53655765 2353687637 IN IP4 1.2.3.4 s=Sales c=IN IP4 1.2.3.4 t=0 0 m=audio 3456 RTP/AVP 0

  5. SIP Success: Products Hard Phones Soft Phones PSTN Gateways Session BorderControllers Firewalls

  6. SIP Success: Service Providers Backhaul, Peering e2e SIP Termination SIP Trunking

  7. SIP Success: Industry

  8. SIP Failure #1: Same Old Telephony

  9. The Telecom Innovation Cycle Deploy ServiceProviders Demand Sell Equipment Vendors Drive Implement Develop SDOs Time

  10. SIP Innovation Failure: Why • Stuck in the telecom innovation cycle • Adopted by service providers with modest goals for innovation

  11. SIP Failure #2: Interoperability SIP Server SIP Server Inter-Domain InterServer example.com Client-Server

  12. Interop Report Card

  13. Too Many Standards

  14. SIP Interop Failure: Why • Too Many Standards • Proprietary Features • Telecom Innovation Cycle (Supply/Demand)

  15. Trend #1: “Cloud Apps” InternetApplicationProvider Proprietary overHTTP (aka webservices) Desktop orMobileNative App

  16. Trend #2: Web Apps InternetApplicationProvider Proprietary overHTTP (aka webservices) Web App(HTML/JS) Browser

  17. Trend #3: Inter-domain “REST” APIs InternetApplicationProvider Open REST API Proprietary overHTTP (aka webservices) Web App(HTML/JS) Desktop orMobileNative App Browser

  18. The Internet Software Innovation Cycle Develop Publish Deploy ServiceProviders Equipment Vendors SDOs Time

  19. Telecoms vs. Internet Application Cycles

  20. Implications for the IETF • Standards provide enabling technologies – not application specific • Inter-domain application standardization only when it is following the telecoms paradigm – many small providers • Client/Server application standardization only when software distribution to the client is not possible
