= G/H meeting 2007-0122 16:00 - 17:30 @ Manila (APAN 23rd) == Next meeting * 30th April, 2007 -> cancel * In March, with APII workshop? * On Saturday we can collocate with APII engineering workshop * March 24th, 2007 == Agenda * Technical Reports * Events scheduling == Introduction by Okamura * Both chairs couldn't attend this time * Prof. Hong couldn't come here neither == APII 10Gbps Upgraded Circuit Implementation Schedule and Network Configuration * (presentation material) === Implementation Schedule for New 10Gbps Network * (schedule diagram) === Existing 1Gbps Network Configuration * (network diagram) * redundancy is set between Busan ADM and QTNet network center ADM === New 10Gbps Network Configuration * (network diagram) * no redundancy === Work & Protection Policy * work & protection policy in case of the existing 1Gbps lines * work & protection policy in case of the new 10Gbps lines * no work & protection between carrier networks * redundant protocol should be set between CPE === Q&A * today's presentation is about layer 1 and 2 * Are there any report about layer 3 services? * Kitamura-san will do * it is not official report, but they say that there were some troubles during initial connections * there was interface matching problem * no detail * after some trials we corrected the error * after rebooting circuit between E300 switches was fine == New configuration of APII JP-KR circuit for more than 1Gbps traffic by Kitamura * (presentation material) * APII JP-KR project * "APII IPv6 R&D testped project" * History of APII JP-KR circuit * network was always congested til 2003 (~8Mbps) * good for QoS testbed * Challenge at Genkai XP in 2005 * 10G link deployment * Current config. of APII KR-JP * (network diagram) * When more than 1Gbps traffic happend... * link aggregation function didn't work well * packet reordering * New configuration * one pipe * wire rate * redundancy * New config. after 10G upgrade * usually a customer gets 1 10G link * no need to consider about redundancy * this time we got 2 10G links * doesn't mean 20G * customer should care about redundancy * Current status * 10Gbps services started already * carrying CERNET traffic between KR and JP after Taiwan earthquake * misconfiguration (fixed) * M10 will retire with coming version of FTOS * L3 service is not ready yet * QGPOP L3 detailed explanation * (...) * in case of QGPOP, QGPOP router can peer with KOREN routers directly * not through Genkai XP E300 or APAN-Tokyo XP * what is misconfiguration about QGPOP routing? * Korean side router announced QGPOP routing information * all the packet to QGPOP is transferred to Korea first and kicked back to Japan * that is KOREN's routing misconfiguration, not QGPOP's * triangle BGP peering * QGPOP announcing our prefix to KOREN * KOREN suddenly started exporting QGPOP prefix to APAN * APAN announce our prefix to SINET * SINET policy was they put high priority from APAN router * QGPOP and Kyushu-U packets went into KOREN == update from Korea side by Sanggyun Kim * several demonstrations on 10Gbps link planned (?) * we still have 2.5G KOREN links, we still need for a while to upgrade our domestic links to 10G * there is a plan to do that * KR side has a lot of collaboration with JP * HIJK meeting * HDTV * with several professional DVTS/HDTV staffs in JP * medical * with Dr. Shimizu * DVTS based * we have a plan to move to HD-level demonstration * e-Learning * Nagasaki & Chungnam Univ. * Cello playing * we don't have much update for this time == HD Live surgery between K-J by Shimizu * (presentation material) * no intensive discussion yet, and we need to discuss * Major Event Plans including K-J * 2.2: China-Korea-Japan Ethics Meeting * 3.6: Thai surgical meeting * 3.22-23: Asia-Pacific HPB Congress * Live surgery: HD uncompressed * (()) * 8.17-19: ELSA-India * (()) * For discussion * Optic fiber to SNU Bundang Hospital * VPN router for gigabit transmission * HD equipments at both stations * Test schedule * 1000 estimated attendants * Press release * Dr. Shimizu's presentation is related to APII workshop * Optic fiber to SNU Bundang Hospital * no one can answer here * SGKim: JWLee investigates situation of Bundan hospital * they have 1G for now * uncompressed HD + DVTS, we need one more 1G link * NIA to support 1G link, otherwise KISDI plans to host APII workshop in Bundang hospital, and they might help (pay for the link) * not decided * not impossible, but critical * iVisto needs 2 1Gbps links (consumes 800Mbps/link) * VPN router for gigabit transmission * a Juniper VPN router can carry 800Mbps, so we are talking with Juniper person * it may be possible * if failed to borrow VPN routers, is it impossible to demonstrate? * may be able to discuss with Dr. Han if it is okay not to use security * how about compressed HDV live surgery and uncompressed HD of stored media? * it is good for participants to show live surgery anyway * no good material of recorded uncompressed HD stream right now * discuss with Dr. Han * we need 4 boxes of Juniper VPN routers * currently Juniper can rent 2 boxes, but not sure 4 is possible * How about using JPEG2000? * 45M - 200M * 300msec system delay * need a special equipment * more discussion and investigation is necessary * HD equipments at both stations * minimum equipment already exist * Test schedule * up to (1) and (2) issues * iVisto will be used * 1 iVisto is installed in KTlab * move it to Bundang hospital * software is already installed into iVisto * Sony HD cam and broadcasting stuff * Bundang hospital's endoscope has HD capability (surgical) (SDI) * that camera can be connected to iVisto directly * if they want to send another view, HD camera is necessary * HD uncompressed image and compressed DVTS/HDV simultaneously is possible * The surgery will be held in Bundang, the conference venue will be in Japan * APII workshop and 10G kick-off * because of Japanese budget issue and some other reasons, March is better * proposal from YJPark that the ceremony should be held in April * in KR side huge conferences will be held at that time * APII workshop and 10G kick-off ceremony will be held on March 23rd and 24th * 23rd in Seoul, 24th in Busan * KISDI is thinking of holding conference in one of the Hotel in Seoul * All the schedule is not fixed yet * we have to send some media from Bundang to the venue Hotel * like to see 10G performance * need 10G link from Bundang to Hotel * up to Korean side * Our live surgery is schedule on 23rd (Fri) * We will have a interesting event in the afternoon on Friday * we maybe able to send event to Seoul venue by HD camera * March is better than April for Japanese...
