2 U N L E A S H I N G A S E R V I C E S R E N A I S S A N C E WCF The Future of the Internet - What Will Tomorrow Bring? Jonathan Rosenberg Chief Scientist

3 U N L E A S H I N G A S E R V I C E S R E N A I S S A N C E WCF What Is The Reality? Toll-bypass Has Been the Primary Motivation Cheap long distance Service transparency Cost Differentials Are Rapidly Disappearing Long distance is now at 5 cents a minute Partial flat rate plans are being rolled out Canadian service providers have moved to a complete flat rate structure Service Transparency Is Far Away QoS issues 911, 1000 features in the 5ESS Huge existing penetration of the phone in the US and worldwide

4 U N L E A S H I N G A S E R V I C E S R E N A I S S A N C E WCF The Question Of Customer Value IP Telephony Service Isnt Cheaper, Better or Different, Why Purchase It?

5 U N L E A S H I N G A S E R V I C E S R E N A I S S A N C E WCF The Big Answer IP Telephony Brings Together Disparate Services - Innovative Services Created by Combining Other IP Applications, Such as Web, , Chat and Presence, with Voice The Killer App for VoIP Lives Within These Combined Services

6 U N L E A S H I N G A S E R V I C E S R E N A I S S A N C E WCF Combined Services Enable Provider Differentiation Combined Services Yield the Feature Exponentiation Effect The number of possible features grows exponentially with the set of applications combined to provide those features With Many Feature Possibilities, Service Provider Differentiation Becomes a Reality VoiceVoice + Web Voice + Web + Voice + Web + + Presence

7 U N L E A S H I N G A S E R V I C E S R E N A I S S A N C E WCF Example Combined Service: Call Park to Web Call Park PBX/Centrex service Service definition Place user on hold, dial number, hang up Go to other extension, dial number, call is active there Problems: UI impossible to use Call Park to Web Place user on hold and park call by clicking park to web Go to other terminal, browse parked call page Click on link and call is picked up! Doesnt matter where the new terminal is located (1) Hold (2) Park to Web (3) Browse Web Calls ( 4) Pick Up Call Original Calling Terminal Called Party Web/App Server New Picking-Up Terminal

8 U N L E A S H I N G A S E R V I C E S R E N A I S S A N C E WCF Enabling Combined Services: The Application Server Architecture Drivers Applications and services will be plentiful Services and features will involve numerous components PCs, phones, IP appliances Entities scattered across providers Third-party and end user service creation key Solution Take decomposition to next step - place services in Applications Server Advantages Softswitch already busy handling SS7 and interop Vastly improves scale Reduces investment risk Allows for access independent services Enables third-party services SS MG SG SCTP Megaco App Server Smart Phone PC Phone App Server

9 U N L E A S H I N G A S E R V I C E S R E N A I S S A N C E WCF Applications Server Programmability Requirements Rapid Service Deployment Is Critical Should Be as Easy to Create a New Phone Service as Building a Web Page Compare PSTN service deployment cycles with Web service deployment cycles Should Be Accessible to All Service providers Enterprise administrators End users

10 U N L E A S H I N G A S E R V I C E S R E N A I S S A N C E WCF Call Signaling in Application Server: SIP Session Initiation Protocol (SIP) Developed in IETF RFC2543, March 1999 Used for Initiation, Modification and Termination of Sessions SIP does not specify what a session is Can be audio, video, Doom game or chat session

11 U N L E A S H I N G A S E R V I C E S R E N A I S S A N C E WCF Call Signaling in Application Server: SIP continued Key Benefits of SIP Highly scalable - leverages IP scalability model Built upon foundation IP protocols - HTTP and SMTP Support of URLs and MIME Good platform for combined services Can carry web pages, Java applets Simple protocol model simplifies APIs Excellent interop story

12 U N L E A S H I N G A S E R V I C E S R E N A I S S A N C E WCF Applications Server Features Support for Several Applications HTTP SIP IMPP Service Logic Triggered Based on Events from Any Application Multiple APIs CPL CGI JAIN Multiple Pieces of Logic Per Event Called and calling party logic Administrator logic

13 U N L E A S H I N G A S E R V I C E S R E N A I S S A N C E WCF Conclusions Industry Directions Dictate a Better Value Proposition for VoIP Combined Services Provide That Value Proposition The Applications Server Architecture Enables Combined Services
