1. CJK NGN test-bed study Phase III&IV
Test-bed Ad-hoc Group

2. Study phases on the CJK test-bed
Phase I: rd/4th Quarter (Completed)
Network Connectivity
Scenario 2 and 4 only (2 CS and 2 domains)
Phase II: st/2nd Quarter (Completed)
Scenario 1, 3 (simpler version of 2 and 4, single domain) and 5
The Phases I & II have attained their original objectives for testing planned. We have decided to revise the scenarios of the phases III & IV as follows and to pursue them as the high-priority study among CJK considering the current NGN requirements.
CJK NGN Test-bed
Phase III: st/2nd Quarter
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
Phase IV: rd ~ nd Quarter
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

3. Test Scenario 6,7 in Phase III & IV
Performance Evaluation with RTP/RTCP-based Measurement extensions
and initial RACF interoperability testing.
Scenario 6-1: Performance evaluation of Network Segments
MoIP (Multimedia (Voice/Audio/Video) over IP) service based on CS and/or IMS
Scenario 6-2: Performance evaluation of MoIP service among CPEs
Local testing of MPM (Provided by KDDI R&D Labs.)
CPE-to-CPE performance evaluation
Scenario 6-3: Performance evaluation of MoIP service with two MPMs
CPE – MPM1 – MPM2 – CPE performance evaluation
Scenario 6-4: Performance evaluation of MoIP service with three MPMs
CPE – MPM1 – MPM2 – MPM3 – CPE performance evaluation
Scenario 7: Testing of RACF and RTP/RTCP-based MPM Interactions
Note: Development of the ATCA (SBC of OKI Electric Industry) based MPM is planned.

9. Schedule

10. Discussions and Results
IP connectivity
Routing equipment, IP addressing, Operation, etc.
●Commercial networks, C-J and K-J networks, have the flexibility in the policy of IP addressing. The IP addressing will be decided considering the routing functions of the existing IP network (R&D network) between China and Korea
Services
Testing priority of Voice, Video, Audio (RTP streams)　
●Voice  Video
Types and specifications (wide/narrow-band etc.) of CODECs should be discussed
Target dates of Scenario 6-1,6-2,6-3,6-4 and 7
C-J , K-J, C-K testing
●Scenario 6-1 and Scenarios 6-2: July 2008 (13th NGN-WG)
Scenario 6-1 and 6-2
Testing procedures,
Drafting of the checking sheet,
instauration of MPM (importation)
●Discussion will be made using reflector and teleconferencing by the end of May 2008.
Specifications of Call servers (C and K)
●Specifications will be provided by C and K by end of April.
Reporting
Rotating the role among CJK
●The reports will be created at the CJK NGN-WG meeting (Lead author will be a person from the hosting SDO).
