This presentation summarizes recent experiments investigating the availability of high-performance applications. It outlines proposals to equip measurement machines across all networks, including HDTV demonstrations from Osaka University over IPv6. Key findings emphasize the importance of end-to-end testing and detailed loss measurement, highlighting applications such as real-time video transmission. The use of multiple measurement points allowed for effective identification of loss areas. The need for enhanced bandwidth and precise measurement tools is evident as high-performance applications increase in frequency.

  1. Experienceof High Performance Experiments Yoshinori Kitatsuji Tokyo XP KDDI R&D Laboratories, Inc.

  2. Summary • Recent experiments of availability investigation for High performance application demonstrations • Proposal to equipping measurement machines every networks

  3. Requirements • Osaka University was planning HDTV over IPv6 demonstrations in NPACI AHM in March 2003 • 100Mbit/s + • From Osaka to SDSC • Washington University was planning HDTV demonstration in APAN Busan Meeting • 220-250Mbit/s • From Portland to Busan meeting venue

  4. A i i i i i Osaka University HD application in March 2003 TransPAC (Seattle) R Abilene R R POS OC192 R POS OC12 R ATM OC12 Tokyo XP R R R R Osaka University R NPACI AHM Venue R ATM OC12 JGNv6 R A

  5. Learn from Osaka University HD application • Every hop measurement is important to find where loss occur • Install PC equipping iperf as much as possible • Osaka Univ, Tokyo Univ, SDSC (NPACI AHM venue) • Long period (5 min – 30 min) period avilability should be checked • At last, the demonstration experienced unperiodically burst loss, even iperf test with short period test was clear. • Seek Shaping parameter in JGNv6 • Multiple Project establishes PVCs over Japan • Service is UBR

  6. A A i i i i i i i Lesson for HD application, Aug 25 APAN Busan Meeting Venue GbE University of Washington (Tyco DC) R KOREN POS OC12 R GbE Tokyo XP R R R R WIDE Project Genkai XP ATM OC12 e! Project GbE

  7. Lesson for HD application (Aug. 25)(Cont.) • Tokyo/Genkai XP • The first high bandwidth stream transmission by the real application through APII link between XPs • Japan Gigabit Network • ATM Multiple OC12 links • Multiple Project establishes PVCs over Japan • Service is UBR • Multiple measurement machine was prepared in both XPs • All machines equip IPERF. • ATM-II PIC for Juniper M20 was installed at Tokyo XP to enable over 270Mbit/s shaping for a PVC. • Other Parts • Juniper supported to provide the Routers at ends of US/JP link. • US/JP link (OC12 SONET) is donated from Tyco to WIDE Project. • Measurement machines equipping IPERF were installed at SRC/DST points.

  8. Learn from preparation of HD application • Multiple measurement point worked very well to find where loss occurs. • End-to-End test is important besides hop-by-hop test. • JP src test didn’t shows loss but US src did. • Multiple measurement was done at the same time. • Need some usage information sharing method • Genkai Link has periodical loss • Another measurement machine is required to figure out what happens and where it is. • Large burst size worked for real time application. • rtVBR: Peak=540Mbit/s, Sustain=500Mbit/s, Burst=4K • JP-KR link and some part of APAN Tokyo XP started to support Jumbo frame.

  9. Proposal form preparations of several demonstrations • Performance measurement machine is getting required in every measurement point • Multiple machines should be installed to enable local loop test • UDP/TCP over IPv4/IPv6 • Authorized operators and users share machines in multiple points • Measuring status (who, how much bandwidth, how long) should be precisely updated and opened to users of measurement machine • Web based operation may helps app users to have test by them selves • High performance Application using APAN/TransPAC increase. The each apps. requires more bandwidth before. • Number of HP apps use or demonstration is also getting increase • Providing measurement tool to such user helps to investigate problems by themselvs
