5 Pune, India, 13 – 15 Dec 2010: ITU-T Kaleidoscope 2010 – Beyond the Internet? Innovations for future networks and services 5 Innovation Fields Security Secured channels Data confidentiality Network reliability Governance Simplified network management Managed services Easy customization High performance User autonomy (Self-Care portals) Sustainability Virtualization Ecology

6 Pune, India, 13 – 15 Dec 2010: ITU-T Kaleidoscope 2010 – Beyond the Internet? Innovations for future networks and services 6 Basic Call Setup Flow

7 Pune, India, 13 – 15 Dec 2010: ITU-T Kaleidoscope 2010 – Beyond the Internet? Innovations for future networks and services 7 SIP Business Trunking – Signaling Model ISDN Like Signaling is decoupled by IP-PBX and Media is anchored by the IP-PBX using a Media Termination Function to emulate a PBX behaviour Pure SIP Signaling goes peer-to-peer between IP-PBXs Hierarchic Signaling between IP-PBXs is manipulated by a centralized harmonization function (HF) that can also anchor the media

8 Pune, India, 13 – 15 Dec 2010: ITU-T Kaleidoscope 2010 – Beyond the Internet? Innovations for future networks and services 8 SIP Business Trunking – Signaling Model Class 5 Softswitch IP-PBX MTP Class 5 Softswitch IP-PBX HF ISDN-Like Pure SIP Hierarchic Class 5 Softswitch MTP

9 Pune, India, 13 – 15 Dec 2010: ITU-T Kaleidoscope 2010 – Beyond the Internet? Innovations for future networks and services 9 SIP Business Trunking - User Plane Models Fixed Media RTP is anchored by IP-PBX The core network it is not affected by media changing related to services invocation IP-PBX needs a Media Termination Function to perform media anchoration Variable Media RTP is peer-to-peer The core network must manage all the RTP negotiatons due to user services invocation IP-PBX can implement various type of services and use several types of codecs

10 Pune, India, 13 – 15 Dec 2010: ITU-T Kaleidoscope 2010 – Beyond the Internet? Innovations for future networks and services 10 Pure SIP Model – Service invocation

11 Pune, India, 13 – 15 Dec 2010: ITU-T Kaleidoscope 2010 – Beyond the Internet? Innovations for future networks and services 11 Go to market approach Full Jacket Pre-packaged solution Low customization High reusability Customer Tailored High customer requirements compliancy High customization possibility High costs for deployment and certification

12 Pune, India, 13 – 15 Dec 2010: ITU-T Kaleidoscope 2010 – Beyond the Internet? Innovations for future networks and services 12 Services Enabler Features To implement New Services the network must leverage the following capabilities: Identity management & certification Voice-Video codec/rating adaptation Signaling harmonization Security & Encryption capabilities Management of specific peculiarities Accounting capabilities

14 Pune, India, 13 – 15 Dec 2010: ITU-T Kaleidoscope 2010 – Beyond the Internet? Innovations for future networks and services 14 IDAD Media Anchoring Class 5 Softswitch BE IP-PBX Enterprise A Enterprise B Class 5 Softswitch BE IP-PBX Enterprise A Enterprise B No Media Anchoring Media Anchoring IDAD

15 Pune, India, 13 – 15 Dec 2010: ITU-T Kaleidoscope 2010 – Beyond the Internet? Innovations for future networks and services 15 Interdomain features harmonization

16 Pune, India, 13 – 15 Dec 2010: ITU-T Kaleidoscope 2010 – Beyond the Internet? Innovations for future networks and services 16 Network Semplification A measure of complexity can be assessed in proportion to the possible combination of all the devices involved. When a new domain is added, the complexity with IDAD is significantly minor than without:

17 Pune, India, 13 – 15 Dec 2010: ITU-T Kaleidoscope 2010 – Beyond the Internet? Innovations for future networks and services 17 SIP Business Trunk Benefits Fast provisioning High performance & reliability Governance Cost savings Replacement of local telephone connections with VoIP gateways Reduction in IT operating costs Growth More efficient communications platforms Improved services Smart migration Acceleration of communications processes for greater efficency Support for community and semi-formal teams

18 Pune, India, 13 – 15 Dec 2010: ITU-T Kaleidoscope 2010 – Beyond the Internet? Innovations for future networks and services 18 Lesson learned Facts SIP Trunking will permit creation of new services for VoIP business market Standardization facilitates interoperability Manufacturers extend standards with proprietary customization to provide new services IDAD is the trade-off between time to market and standardization.

19 Pune, India, 13 – 15 Dec 2010: ITU-T Kaleidoscope 2010 – Beyond the Internet? Innovations for future networks and services 19 Back Up Slide

20 Pune, India, 13 – 15 Dec 2010: ITU-T Kaleidoscope 2010 – Beyond the Internet? Innovations for future networks and services 20 Basic Call Setup Flow

21 Pune, India, 13 – 15 Dec 2010: ITU-T Kaleidoscope 2010 – Beyond the Internet? Innovations for future networks and services 21 Pure SIP Model – Service invocation

22 Pune, India, 13 – 15 Dec 2010: ITU-T Kaleidoscope 2010 – Beyond the Internet? Innovations for future networks and services 22 Hierarchic Model - Service Invocation

23 Pune, India, 13 – 15 Dec 2010: ITU-T Kaleidoscope 2010 – Beyond the Internet? Innovations for future networks and services 23 ITU Standardization vs IDAD The strengthening of the standards is the main way to go forward for multi-vendor interoperable solutions, but its a must also consider the presence of several small/medium players that perform customization to provide services. IDAD is the trade-off between time to market and standardization.
