n Nation wide ATM base network (OC3, OC12)

3 JGNv6 Network(1)

JGNv6(Japan Gigabit Network for IPv6)

n IPv6 overlaying on the JGN’s ATM network

n Various vender Routers (five vendors now)

n Native IPv6 service, i.e., No-Tunneling

n The largest native IPv6 R&D network in the world

n Test Operation ; October 2001

n General Service ; April 2002

4 JGNv6 Network(2)

Core sites n Tokyo(Univ. of Tokyo) Osaka(NTT Dojima) n Fukuoka(Kyusyu Univ.) n Okayama(IPv6 Okayama Interoperability and Evaluation Laboratory) An access point are over nation wide. n 28 router sites. n 29 bridge sites. External connectivity, e.g., Abeline, APAN, v6pc Evaluate the interoperability and applicability of new functions, e.g., multicast, IPSec.
