1. Introduction
 New Question on DSN in ITU-T SG 13
 Q.19/13: Distributed Services Networking
 Target of DSN;
 Bring new technologies such as P2P to NGN so as to
leverage the performance of service and
 Reduce the CAPEX and OPEX by utilizing the resources
in P2P paradigm
 Current Definition of DSN;
 the evolution of NGN as well as legacy IP based network,
which provides distributed, operatable and manageable
characteristics, to support various multimedia services
 Leaders of Q.19/13
 Rapporteur : Mr. Jin Peng (China)
 Associate Rapporteur : Mr. Shin-Gak Kang (Korea)

3. Current Issues of Q.19/13
 Clarification of the Title of Question 19/13
 It was proposed to change the term ‘DS Networking” as,
 “Distributed Service Network”
 Why ?
 DSN is considered as the evolution of NGN as well as
legacy IP based network with distributed technology
 DSN is the Overlay Network; not Technology
 It needs to be clarified at the next meeting in Sep. 2009
 Concentration on DSN Requirements to complete it
as soon as possible
 Target date for Consent: Jan. 2010
 Need more considerations about relationship bet.

4. Relevant Activities
 ITU-T Q.15/11 (End-to-end Multicast)
 Develop Recommendations on End-to-end Multicast Solutions
 Framework and Protocols for multicast communications
 Relevant Tasks of Q.15/13 is to develop,
Rec. on end-to-end Multicast communications protocols
based on P2P technology to support streaming service
such as IPTV and UCC
 Rec. on end-to-end Multicast communications protocols
over NGN environments
 Collaboration with ISO/IEC JTC 1/SC 6 on end-to-end
Multicast Solutions
 Preliminary Joint Work Item: Streaming protocol based on
Managed P2P technology

5. Next Step of Q.19/13
 Draft Study Roadmap of Q.19/13
 2010.01~2010.12: Architecture and Key Issues Phase 1
 2011.01~2011.12: Architecture and Key Issues Phase 2
 What’s the Key Issues after completion of DSN
Architecture Framework
 DSN Capabilities ?
 Detailed Functional Architectures for each Specific Services ?
 Protocols to provide DSN service scenarios based on DSN
Architecture ?
 Methods and Mechanisms to support DSN ?
 Collaboration and Coordination with other relevant
Groups should be considered in the next step of Q.19
work to realize DSN

6. Conclusion
 Urgent Issus of Q.19/13
 Clarify the Term and Scope of Q.19/13
 Work Priority on Scenarios and Requirements
 Setup Concrete Architectural Model of DSN
 Future considerations
 Specify the next Key Issues for DSN Standardization
 Collaboration with other relevant Groups to realize and
deploy DSN
 CJK Collaboration is the Key Success Factor of DSN
 Most of DSN standardization activities have been Participated
and Contributed by the CJK members
