  5. Testing Network Architecture • APII Testbed • Korean Side • Name: KOREN • NOC: KIX in NCA • Connectivity: • POS OC3: 155 Mbps to China • 2 x 1Gbps Ethernet to Japan • China/Japan Side • TBD • Type • IPv4/IPv6 network • No MPLS & other QoS functionality available yet • TBD • Need investigation on MPLS/QoS support • Current link capacity may not be enough

  6. Signaling Link Bearer Link ETRI’s CS Lab Network Configuration Japan CERNET 155M POS Internet Border Router 2G Ethernet Support Facility GBE Management/ Monitoring System, GW, SIP phones, … GBE, 100BT, 10BT Meeting Room 100BT SBC 100BT(VLAN) L2 스위치 100BT 100BT 100BT 100BT 100BT AS/MS CS SG/TG RACF Packet Monitor E1 TDM 100BT PSTN 모델망

  7. Test Scenarios and Items • Target Test Scenarios • VoIP Interworking • PES/PSS Interworking • VoIP Performance Evaluation • PES/PSS Performance Evaluation • VOIP/PES/PSS Interworking with RACF Involvement • Testing Items • Basic Functionality Testing cases • Call Setup • E2E Call Setup Delay • Call Completion Rate • Each Segment IPTD/IPDV/IPLR/Path unavailability • Call Traffic Accounting • Harmonization Testing ofService QoS class differences among CJK • Equipment Related Testing cases • Various User Terminal Testing • Network Related Testing cases • IP address allocation • Network connectivity setup • Etc.

  8. Testing Schedule Proposal • Phase I: 2006 3rd/4th Quarter • Network Connectivity • VoIP Testing • VoIP Performance Evaluation • First Report/Demo during 8th CJK NGN Meeting (2006 Nov or Dec) • Phase II: 2007 1st/2nd Quarter • PES/PSS Interworking • PES/PSS Performance Evaluation • Second Report/Demo during 10th CJK NGN Meeting (2007 July or Aug) • Phase III: 2007 3rd/4th ~ 2008 1st/2nd Quarter • VoIP/PES/PSS Interworking with RACF involvement • Performance Evaluation for VoIP/PES/PSS Interworking with RACF involvement • Third Report/Demo (2008 July or Aug)
