study phases on the cjk test bed
Study Phases on the CJK Test-bed
  • 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(In Progress)
    • Scenario 1 and 3, (simpler version of 2 and 4, single domain)
    • Status Report at the 11th CJK NGN Meeting (February 2008)
  • Phase III: 2007 3rd/4th ~ 2008 1st/2nd Quarter
    • Scenarios 5 ~ 7
    • Performance Evaluation of RTP/RTCP-based passive measurement

(led by TTC)

    • Initial RACF Interoperability testing (led by TTA)
    • Status report will be provided at the 11th CJK NGN Meeting in 2008.2
  • Phase IV: 2008 3rd ~ 2009 2nd Quarter (Proposal)
    • Scenario IPTV Interoperability testing
    • Performance Evaluation of IPTV services based on RTP/RTCP-based passive measurement
    • Continued RACF Interoperability testing
    • Testing of RACF and RTP/RTCP-based MPM Interactions

We are here

test scenarios
Test 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 extension
  • Scenario 7: Call Servers across multiple NGN Network Domains with PSTN, Value Added Services and RACF Involvement (to be confirmed at the 11th CJK Meeting)

Initial target

scenario 6 a part of 7 proposal
Scenario 6 (& a part of 7) (Proposal)

Target Services

Voice/Audio stream (IP telephony)

Basic SIP based signaling

IMS based signaling

Video stream (e.g. IPTV)

unicast based sending

multicast based sending

no signaling

Basic SIP based signaling

IMS (+RTSP) based signaling

Entities Under Test

RTP translator based evaluation

Cooperation with RACF (MPM application)

PMP-FE, PME-FE (Mp, Mr)

RACF (MPM application)

PMR-FE (Mi)

PMR-FE (Mu)

2008 1Q~2Q

2008 3Q~4Q

2009 1Q~2Q

ready for tests

to be prepared

rtcp based performance evaluation tests
RTCP based Performance Evaluation Tests
  • Firstly, go forward with RTCP based performance evaluation tests described in Y.mpm Appendix II
  • RTCP covers major metrics

RTCP XR VoIP Metrics

RTCP XR Statistics Summary Metrics

RTCP XR Video Metrics

supported report blocks of rtcp
Supported Report Blocks of RTCP
  • RTCP SR/RR (Sender/Receiver Report)
    • Defined in the IETF RFC 3550
    • Sender/receiver report, for basic transmission and reception statistics
  • RTCP XR (eXtended Report)
    • Defined in the IETF RFC 3611
    • Extended reporting format to convey information that supplements the statistics that are contained in the report blocks used in RTCP SR/RR
    • In particular, the VoIP metrics report block is specified for voice applications
  • RTCP XR Video Metrics
    • Defined in the IETF Draft
    • Extensions to the RTCP XR to support the monitoring of video over IP for IPTV and videoconferencing endpoint reporting
  • RTCP HR (High Resolution)
    • Defined in the IETF Draft
    • Extensions to the RTCP XR to support Voice over IP (VoIP) monitoring for services that require higher resolution or more detailed metrics

RTCP SR/RR

Extend statistics and VoIP metrics

RTCP XR

Support higher resolution for Voice over IP

Support Video over IP

RTCP XR Video Metrics

RTCP HR

test items
Test items
  • item 0: Performance evaluation on CPEs
    • CPEs evaluate performances and send them end-to-end
    • CPEs should support sending/receiving RTCP packets
  • item 1: Performance evaluation using single MPM
    • A MPM is enabled between CPEs
    • A MPM evaluate performances of the RTP stream
    • CPEs should also support receiving RTCP packets from MPMs
  • item 2: Performance evaluation using multi MPMs
    • Two (or more) MPMs are enabled between CPEs
    • MPMs send/append evaluated performances
    • CPEs should also support receiving multiplexed RTCP packets from MPMs
an implementation of mpm
An implementation of MPM
  • RTP translator including MPM
    • RTP translator includes the MPM and transport function (L3 switch)
    • PME-FE in MPM monitors RTP/RTCP packets to execute performance measurement
    • PMP-FE processes the performance analysis and aggregation
    • PMR-FE reports the measurement data to other MPMs via Mi reference point implemented as additional RTCP
next steps
Next Steps
  • Preparation for RACF interoperability testing and Phase IV testing(IPTV, RACF and MPM testing)
    • Test-case specification
    • System setup
    • Testing scenarios
  • Budget support for the additional testing by each SDO
  • Finding collaboration opportunities with other related Testing Programs (e.g., BcN test-bed, KDDItest-bed)
  • Miscellaneous configurations for performance evaluation of RTP/RTCP-based passive measurement
    • Codecs
      • VoIP: G.711u-Law, G.729A
      • Video/Audio: H.264 MPEG-4 AVC + MPEG-2 AAC
    • RTP payload format
      • Video and audio streams are sent over different RTP sessions
