2008. 2. 22 CJK NGN Test-bed Ad-hoc Group

1. 2008. 2. 22 CJK NGN Test-bed Ad-hoc Group 11th CJK NGN-WG (CJK NGN Test-bed Activity Report)

2. Contents • Meeting Discussion Results • Agreed Test Scenarios & Actions • Agreed Scenarios for Performance Monitoring • Agreed Schedule Changes • Measurement segments by MPM • Network Configuration for Scenario 6 & 7 • Test Scenarios Details • Further Discussion Items • Next Steps

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. 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. Agreed Scenarios for Performance Monitoring • Scenario6-1: 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 • Scenario6-2: Performance evaluation of MoIP serviceamong CPEs • Measure RTP/RTCP performance of MoIP（Multimedia（Voice/Audio/Video) over IP）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. Agreed Schedule Changes • Phase I: 2006 3rd/4th Quarter (Completed) • Network Connectivity • Scenario 2 and 4 only (2 CS and 2 domains) • Status Report during 8th CJK NGN Meeting (January 2007) • Phase II: 2007 1st/2nd Quarter(Completed) • Scenario 1 and 3, (simpler version of 2 and 4, single domain) • Status Report at the 12th CJK NGN Meeting (March 2008) • Phase III: 2008 1st/2nd Quarter (Proposed) • Performance Evaluation of RTP/RTCP-based MoIP （Multimedia（Voice/Audio/Video) over IP） service • Network connective for Performance evaluation and Performance Monitoring Scenarios 6-1 and 6-2 • Status report at the 13th CJK NGN Meeting in 2008. 9 or 10 • Phase IV: 2008 3rd ~ 2009 2nd 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 14th and 15th CJK NGN Meetings

7. Measurement Segments by MPM CPE – MPM1 – MPM2 – MPM3 – CPE (segment: MPM-to-MPM, MPM-to-CPE) 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.

8. Network Configuration for Scenario 6 & 7

9. Test Scenarios Details

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. 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
