I Pv6 NE twork and A pplication T estbed 6NEAT background ASEM has underscored “intellectual exchanges between Asia and Europe”, in 1996 Trans-Eurasia information between the two region Lunched by ETRI, (2001-2002) www.6neat.net Goals Establishing the IPv6-based advanced research network Between Korea and Europe named Trans-Eurasia information network (TEIN). This network will be a network infrastructure for Next Generation Internet between Korea and EU Development and Evaluation of advanced IPv6-support applications and technologies IPv6-based high-quality videoconferencing system Mobile IPv6 system which follows the IETF Mobile IPv6 standard IPv6-based advanced multicast technology

- 11. Application(1) HVCT (High-quality Video Conferencing Tools) HVCT (high-quality video conferencing tool) is a video and audio conferencing tool Developed by ETRI and SNU Feature IPv6-enabled HVCT will be works on Technical-Preview IPv6 stack based on Microsoft Windows2000 Multicast/unicast support We support two types of communication: n-to-n (multicast) and 1-to-1 (unicast). High-quality audio/video (use MP3 codec and MPEG-4 codec) Bandwidth-adjustable Traffic monitoring Simple messenger
- 12. Application(2) Structure of HVCT system The system consists of three parts; encoding manager, network manager, decoding manager. The encoding manager: Process the multimedia data from video camera and microphone and encode the raw data to MPEG4/MP3.The encoded multimedia data is integrated to one stream through the A/V MUX and then passed to network manager. Network Manager: put the encoded data in the RTP payload and then send them to the designated destinations. The decoding manager: Decodes the received data depends on the media type, i.e. audio, video.

- 16. Conclusion The environment of experimental IPv6/IPv4 configured tunneling or IPv6/IPv6 configured tunneling by using TEIN. Native IPv6 network that is connected via ATM connection between ETRI and SNU. The TEIN network Provides informational knowledge infrastructures based on next generation Internet and make a chance of Korea to be a hub of Asia.
