11. 3. 21CN SDP Design

12. Goal: Software & Services on 21CN Embracing the Web, Standard Platforms and Contemporary Software Development Techniques. Agile Service Creation Web & Voice Applications Converging Standard Software Platforms J2EEBPEL WSDL SOA + IMS 21CN Web 2.0 Social Networks SCRUM Sprints VoIP IP MPLS

13. “Switching” and Enterprise Architectures are Merging Fundamental convergence between telecom “platforms” and Enterprise “applications” Software Development moving from proprietary monolithic telecom applications to standards-based layered J2EE applications Now, the “Applications” Developer can focus on the application and leave platform and resiliency issues to the standards-based infrastructure layers ProprietaryProprietaryJ2EEJ2EE Standards (e.g. JSR289, SIP Servlets, J2EE...) Monolithic Applications on Proprietary Platforms are No Longer Feasible.

15. SDP is Network Agnostic Pragmatic Design Approach: Build Converged Services with design anticipation of IMS But Begin NOW Select Standard Network Components as Mature Technology Emerges Bandwidth (UK and Global) Network Access and Security 21CN SDP Service PSTN Mobile SIP IMS IMS is not a Requirement to Begin initial Offerings.

16. 5. 21CN Software Based Services

19. Innovation is now less about creating communications services we’ve never heard of, but instead, focusing on the precise needs of customer segments and uniquely meeting their needs. 21CN provides Customers the service building blocks and finished services to produce rich service experiences The Killer Attributes for SDPs are rapid change driven by embracing new applications both internal and external to the service providers In Closing… Thank You and Good Luck.
