  2. KOREN – Current/Future • Current(2003) • Seoul-Taejon : 2 * 2.5G SONET • Seoul-Suwon : 155M ATM • Taejon-Taegu-Pusan-Kwangju : 2.5G SONET • 40 institutions(21U+19R/32A+8G) • 20 institutions will be added • 5-10 institutions can have GbE connection • International links : APII/1G, TEIN/10M, SingAREN/6M • Future • Seoul-Suwon : 2.5G SONET • Additional nodes, more GbE connections for institutions • 80-100 institutions • International links : APII/1G+(?), TEIN/45M+, MY/45M+, SingAREN/?, CERNET/? KOREN/APII/TEIN NOC(s)

  3. KOREN – E2E Performance • KESG’s NCA Project: Traffic Engineering for Performance Improvementon KOREN/APII • Triggering Vigorous Activities of Cooperative Research Group (KESG) in KOREN • Triggering Research Collaboration between KOREN & QGPOP • Improvement of Network Engineering Capability for KOREN • Sub-subjects: Measurement, Performance, Routing, Security • KESG’s E2E Performance Initiative • Deploy a measurement infrastructure over KOREN and with International peers • Identify performance bottleneck and tune performance • With above 2 activities we(KESG) will support researchers requiring high bandwidth/performance KOREN/APII/TEIN NOC(s)

  4. KOREN - Update • Network Upgrade : Completed • Seoul-Taejon : 2 2.5G POS with 1.6T OLS • Taejon-Taegu-Pusan-Kwangju : 2.5G POS with EON • Seoul-Suwon : still 155M ATM with PP15K • Members • 40 institutions : 21 universities, 19 research institutions • By year’s end : 20 more institutions will be connected • Access link : 32 155M ATM, 9 GbE connections • By year’s end : 5-10 more GbE connections will replace 155 ATM ones KOREN/APII/TEIN NOC(s)

  5. APII/TEIN - Update • Separate projects, but connected to KOREN • TEIN Upgrade Still Negotiated • TEIN(RENATER 3-KOREN) : at least 45M or more • TEIN Extension to MY : at least 45M or more • Additional APII Circuits Negotiated • CN-KR : ? KOREN/APII/TEIN NOC(s)

  10. KOREN/APII/TEIN - Future • Network Upgrade • 2.5G POS planned between Seoul and Suwon • Additional nodes to completely cover the nation • More Members • More GbE connections for more members • Toward a total of 80 – 100 institutions • APII/TEIN Upgrade • APII : more than 1G? • TEIN : 155M? 622M? • Extended TEIN to MY : 45M? 155M? • APII Link to CN? • Remember that all these can be achieved by users. KOREN/APII/TEIN NOC(s)

  11. Some Traffic Graph APII/Genkai TEIN KOREN/APII/TEIN NOC(s)

  12. Some Traffic Graph SingAREN KOREN/APII/TEIN NOC(s)

  13. KOREN – KESG • KOREN Engineering Study Group • Voluntary participation of members in study of KOREN and APII/TEIN Engineering • KHU, KU, CHNU, CNU, KAIST, KJIST, CJNU, HYU, etc • Closely working with QGPOP group of Kyushu with focus on APII/Genkai link • Closely working with Measurement WG of ANF • This year’s project granted by NCA • Traffic Engineering for Performance Improvementon KOREN/APII KOREN/APII/TEIN NOC(s)

  14. KESG – Performance Initiatives • KESG’s NCA Project: Traffic Engineering for Performance Improvementon KOREN/APII • Triggering Vigorous Activities of Cooperative Research Group (KESG) in KOREN • Triggering Research Collaboration between KOREN & QGPOP • Improvement of Network Engineering Capability for KOREN • Sub-subjects: Measurement, Performance, Routing, Security • KESG’s E2E Performance Initiative • Deploy a measurement infrastructure over KOREN and with international peers • Identify performance bottleneck and tune performance • Collaborating first with CRL’s performance project for APII/Genkai and TransPAC links to share each other’s measurement infrastructure and its data • Also planning the TEIN KOREN/APII/TEIN NOC(s)

  15. KESG – PMI • Performance Measurement Infrastructure to measure • N2n(Node-to-node) • NetFlow format data • SNMP • Focused on link layer performance • Eg2eg(Edge-to-edge) • Path measurement from ingress to egress • Active measurement • Focused on network/transport performance KOREN/APII/TEIN NOC(s)

  16. KESG – PMI • Components • Measurement Client (MC) • to measure performance metrics • Data Analysis Module (DAM) • To analyze measured values • Database (DB) • to save analyzed values • Visualization Module (VM) • To visualize analyzed values • Query Module (QM) • to show past values on demand KOREN/APII/TEIN NOC(s)

  17. KESG – PMI • Data Flows VM DAM analyzed data DB raw data QM MC MC Probe packet KOREN/APII/TEIN NOC(s)

  18. KESG - PMI • Cannot cover the whole E2E performance • We need more end-users’ participation in the KESG PMI to make researchers get more performance for their research • This collaboration will help make government feel importance of R+E network and researches based upon R+E network in Korea which all our efforts depend upon. • We need a well-planned cooperation KOREN network engineers and applcation users. Thanks! KOREN/APII/TEIN NOC(s)
