3. The 11th CJK NGN-WG Meeting 3 Meeting Discussion Results Test items and their schedule should be clarified. For example, what is the implication of the test for IPTV. Network environment, which is going to be the mixture of R&D and commercial networks: if they turned to be all R&D networks, it is easy to support high-speed traffic such as video. If they turned to be all commercial networks, we do not have to worry about background traffic, but need further investment. Further involvement of other participants: TTA will check further involvement of the government initiatives (till the next meeting). CCSA will check the possibility of further involvement by the company who are interested in IPTV performance measurement. Other methods beyond RTP/RTCP passive measurement. After the discussion by ad hoc team, the following test plan was proposed and agreed by the meeting, which is given in 11thNGN-WG_021.

4. The 11th CJK NGN-WG Meeting 4 Agreed Test Scenarios & Actions Scenarios 2 & 4 are completed Scenarios 1, 3, & 5 are considered as the slight variations of the scenarios 2 & 4. Ad-hoc group agreed not to conduct the testing since the testing of the scenarios 2 & 4 fulfilled the objectives Thus Phase I & II are considered to be completed Scenario 6 & 7 are our target for joint testing efforts for Phase III & IV For the reference the following are original 7 scenarios –Scenario 1: Single Call Server within a single NGN Network Domain without PSTN –Scenario 2: Call Servers across multiple IP Network Domains without PSTN –Scenario 3: Single Call Server within a single NGN Network Domain with PSTN –Scenario 4: Call Servers across multiple NGN Network Domains with PSTN –Scenario 5: Call Servers across multiple NGN Network Domains with PSTN & Value Added Services –Scenario 6: Performance Evaluation with RTP/RTCP-based Measurement extensions –Scenario 7: Call Servers across multiple NGN Network Domains with PSTN, Value Added Services and RACF Involvement

5. The 11th CJK NGN-WG Meeting 5 Agreed Scenarios for Performance Monitoring Scenario 6-1: Performance evaluation of Network Segments –Measure Network Performance Metrics among CJK independent from services –Measured results can be cross referenced by subsequent tests for accuracy –Periodic and constant measurement –Measurement intervals and other details to be defined –IPTD, IPDV, IPLR of C-K, C-J, J-K, J-C, K-C, K-J Scenario 6-2: Performance evaluation of MoIP service among CPEs –Measure RTP/RTCP performance of MoIP （ Multimedia （ Voice/Audio/Video) over I P ） service based on CS and/or IMS –CPE-to-CPE performance evaluation Scenario 6-3: Performance evaluation of MoIP service with two MPMs –Measure RTP/RTCP performance of MoIP service based on CS and/or IMS –CPE – MPM1 – MPM2 – CPE performance evaluation Scenario 6-4: Performance evaluation of MoIP service with three MPMs –Measure RTP/RTCP performance of MoIP service based on CS and/or IMS –MPMs send/append evaluated performances –CPE – MPM1 – MPM2 – MPM3 – CPE performance evaluation

6. The 11th CJK NGN-WG Meeting 6 Agreed Schedule Changes Phase I: 2006 3 rd /4 th Quarter (Completed) –Network Connectivity –Scenario 2 and 4 only (2 CS and 2 domains) –Status Report during 8 th CJK NGN Meeting (January 2007) Phase II: 2007 1 st /2 nd Quarter (Completed) –Scenario 1 and 3, (simpler version of 2 and 4, single domain) –Status Report at the 12 th CJK NGN Meeting (March 2008) Phase III: 2008 1 st /2 nd Quarter (Proposed) –Performance Evaluation of RTP/RTCP-based MoIP （ Multimedia （ Voice/Audio/Vide o) over IP ） service –Network connective for Performance evaluation and Performance Monitoring Scenarios 6-1 and 6-2 –Status report at the 13 th CJK NGN Meeting in 2008. 9 or 10 Phase IV: 2008 3 rd ~ 2009 2 nd Quarter (Proposed) –Performance Evaluation of RTP/RTCP-based MoIP and IPTV services –Performance Monitoring Scenarios 6-3 and 6-4 –Initial RACF Interoperability testing : Scenario 7 –Testing of RACF and RTP/RTCP-based MPM Interactions –IPTV Interoperability testing –Status report at the 14 th and 15 th CJK NGN Meetings

7. The 11th CJK NGN-WG Meeting 7 Measurement Segments by MPM Note: MPM stands for Management of Performance Measurement for NGN. It is based on the ITU-T Recommendation Draft Y.mpm. MPM used throughout this document is a system realized based on the capabilities defined in Y.mpm. CPE – MPM1 – MPM2 – MPM3 – CPE (segment: MPM-to-MPM, MPM-to-CPE)

10. The 11th CJK NGN-WG Meeting 10 Further Discussion Items Functions of MPM and CPE Measurement intervals and metrics Background traffics Specifications of the existing system (e.g. Call server) Type of RTCP extensions Mixture of the R&D network and commercial network Commercial service providers and solution vendors involvement Finding collaboration opportunities with other related Testing Programs (e.g., BcN test- bed) Other performance evaluation methods besides RTP/RTCP-based passive measurement （ Active measurement)

11. The 11th CJK NGN-WG Meeting 11 Next Steps Deliver the completed testing report of Phase I & II Complete IP network connectivity among CJK –R&D Network between C – J and Commercial Networks between C-J and K-J Define detailed Test-bed Network Configuration Define detailed Test Scenarios and Test Items Target date for the above efforts is March 31, 2008
