Proposal from TTA　1
ETRI will upgrade our CS platform so that other tests can be available including PSTN interworking, IAD, AG support, etc.
QoS consideration for transport
Preparation for Phase 3 testing
What about IMS-based Interop testing?
Need budget support for more meaningful tests
Collaboration opportunities with other Testing Programs? (In Korea, we have BcN test-bed. What about others?)

Action items
Preparation of HD video encoder, set-top box, IMS server
Preparation of test spec and procedures
Setting up of IMS-based HD IPTV testbed
Interoperability test for multicast, IMS, QoS, etc.
QoE, QoS parameter measurement

7. Issue on performance management
How do we co-relate end-to-end QoE to individual network segment performance?
For network design and resource planning
For fault localization and rerouting
For feedback to session admission at session establishment
For feedback to bandwidth change during a session (main interest)
Assumption
Real time traffic, measurement basis, and passive measurement
Most sessions of multimedia services over IP-based networks use RTP (Real-time Transport Protocol)
=> RTP traffic and RTCP(RTP Control protocol) -based mechanism
Technical issues
Correlation between end-to-end and network segment performance results
Efficiency and accuracy of performance estimation, e.g., minimizing RTCP flows and accuracy of estimation
Effectiveness of measurement-based bandwidth control 7

8. Proposal
We propose a test-bed study that addresses the performance evaluation issue referred to in the Phase III testing of the CJK test-bed (2007 3rd/4th ~ st/2nd Quarter).
●Study items
Feasibility tests of the measurements and management of the U-plane information (QoE/QoS information) for RACF.
Measurement of the QoS (network performance) information of each network segment using RTP/RTCP based passive measurement.
Collection and management of the QoE information which is estimated at the TEs by the network nodes (Border Gateways (BG)) using RTCP packets.
Tests of the accuracy of the QoS information measured and refresh interval of the management of the QoE/QoS information.
Model: Bidirectional unicast connection which includes 2 RTP endsystems TE A and TE B connected through 2 RTP translators BG 1 and BG 2. 8

9. Proposal (continued) ●Schedule ●Discussions ～2008.3：
Creation of an environment for a test-bed; networks, prototype system for passive measurements based on Y.mpm.
KDDI is developing prototype systems and checking an arrangement of international networks for this test-bed.
2008.3～：
Testing RTP applications such as VoIP, VoD, Network games (with multimedia), etc.
●Discussions
What will be the test items and steps?
What features would be implemented in this prototype system?
Who will host and provide the testing facility?
etc. 9
