Deployment of WIDE IPv6 network 1996 - started with 64k leased lines We are trying to avoid tunnels from day one 1997 - steal bandwidth from IPv4 backbone (ATM pipes) 1998 - JB: nationwide ATM research network, funded by government With IPv6 we can get circuits cheap :-P 2000 - 200 to 300Mbps class IPv6 native backbone, nationwide 2002 - Gbps-class native backbone, nationwide 2004 - 10Gbps-class native backbone, nationwide/trans-pacific Researchers have trouble with tight IPv4 address allocation policies IPv6 is the solution for them! 30Mbps digital video multicast traffic, for remote classrooms (Wisconsin - Yokohama) MP3 audio over multicast + IPsec, xcast (small group multicast), IPv4/v6 over satellite medium, diffserv experiments/operations Of course, routing experiments/operations - OSPFv3/BGP4+ Early deployment = more experience than others = advantage
