Summary of Session 3 SDP technology evolution

1. Summary of Session 3SDP technology evolution Naotaka Morita Session Chair NTT, SG13 Vice-Chairman

2. Summary of S-3 • Components, Changsup Keum (ETRI) • Views from vendors, Rui Wang (ZTE) and Kaoru Kenyoshi (NEC) • A view from telecom service providers, Jaroslaw Budzisz (Telekomunikacja Polska)

3. SDP components • Mr. Sup of ETRI showed the evolution trend on convergence from fixed mobile convergence, telecom and IPTV convergence, telecom and Internet, and forthcoming multiple industry domain convergence along with M2M and IoT. • He stressed that SDP is becoming more and more important as the focal point of the value provisioning according to his rich experiences from 2004 of their initial production of Parlay gateway. • He introduced ETRI SDP, which already extends the current ITU-T Rec. to support social networking and knowledge sharing. Open source components adopted by ETRI was also introduced. • His view expands to Future Smart SDP, whose requirements include data-awareness, such as big data handling, and content-oriented networking as is just started under Smart Ubiquitous Networks (SUN) concept in ITU-T. • He is now studying modules suitable for distinct services across multiple industry domains beyond telecommunication and ICT.

4. Views from vendors • Mr. Wang of ZTE showed several successful deployments of SDP with four domains, i.e., factory behind store mode, IPTV, IMS/M2M, and cloud. The deployments ranges from China to many other countries including multi-country SDP model. • He concluded with requirements in standard, which are interfaces between different SDP subsystems (e.g., access gateway, management, and portal), mechanisms to support distributed deployment in different administrations and countries, and API enhancement.

5. Views from vendors • Mr. Kenyoshi of NEC shed light on SDP from carrier cloud perspective in his humble manner. • He would like to seek the path from IT-centric to ICT-centric model (i.e., contribution from Communication part) to increase carrier opportunities. • His view explores agricultural and ITS with protocol implications, such as more simplicity, tolerability, and real-time sensitivity brought by his signalling competence as SG11 vice-chairman. Unified architecture should be considered to meet possible distinct requirements. • He referred to Japan’s consortium of M2M and cloud services in Japan (http://www.ngm2m.jp/index.shtml). • To make it successful, carrier cloud needs deep consideration of IT, network, and device technologies and their cooperation. Cooperation beyond industries becomes more important as well. • In addition to the current data center simply residing over the network, further interaction with network should be considered. • SDP modules specific to M2M need further study.

6. View from service provider • Mr. Budzisz of Telekomunikacja Polska introduced their valuable experiences of IMS deployment. He reminded us of the importance of speed, cost, and interoperability for service deployment. • Some services are already available such as high-definition voice and parallel ringing. • On hardware, the latest IMS implementation allows more compact packaging of multiple functional elements (e.g., HSS and several CSCFs) into a single ATC chassis. • Further standards may be necessary when rich communication services extends to multiple operators.
