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 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

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] Tokyo XPSeoul XP KT Lab/ Seoul KAIST/Taejon 6MbpsT1
