  3. High Performance Mbone Application Definition[KAIST97] a set of applications of data rate equal to or higher than the bandwidth of T1 link Specification Audio application - higher than FM Quality(16/22kHz mono/stereo) Video application - higher than SCIF(704X576) resolution Shared whiteboard - negligible impact on network bandwidth Prototype systems environment Pentium 133MHz, 64MB RAM, FreeBSD-2.2.5/Linux-2.0.32 Frame Grabber: Matrox Meteor, Soundcard: Gravis UltraSound performance Audio application - 270~720kbps with 16/22kHz mono/stereo Video application - less than 1Mbps with SCIF resolution Shared whiteboard - less than 64kbps

  4. Plan Network KR-JP link(ATM level) is being tested KR-JP link(IP level) would be up in March 1998 APAN-KR Multicast testbed PIM-DM will be deployed on KR-JP Multicast tunnel (between Cisco routers) Global Mbone connection through APAN network is considered Research Activity New Internet Multicast Routing Architecture[Meyer97] deployment MBGP testbed between KT and KAIST(plan) GateD-Multicast(version 5)[Merit98] KT Lab/ Seoul Tokyo XP Seoul XP KAIST/Taejon 6Mbps T1

  6. Classification of High performance Mbone applications 1st level Network bandwidth : T1/E1 (1.5~2Mbps) Audio quality : FM quality audio (8~22kHz) Video quality : 640x480 resolution Recommendation : VIC with NV format, large size, quality 0 Software Release 2nd level Network bandwidth : T2/E2 (6~8 Mbps) Audio quality : CD quality audio(44.1kHz, 16bit sampling) Video quality : 800x600 resolution 3rd level Network bandwidth : T3~OC12 (45~620 Mbps) Audio/Video quality : HDTV quality (1920x1480) 4th level Network bandwidth : OC-48~(Gbps) Audio/Video quality : 'tele-immersion'
