IPv6 Joint Experiment Report in 2000

　

History

April 2000

 We have been allocated IPv6 address space 2001:200:125::/48 by WIDE project.
Routing information is announced by RIPng.

April 2000

 We participate in the experiment of SOI (School on the Internet).

　

Network Structure

We are connected to 6bone-jp through Otemachi POP using IPv6-over-IPv4 tunnel.We use PC running FreeBSD with KAME as IPv6 router.Machine specification is following:

IPv6 router for the 6bone-jp

CPU Pentium III 500Hz
MEM 256MB
NIC Alteon ACE NIC (1000BaseSX Gigabit Ethernet: IPv6 native)

DV sender

CPU Celeron 466MHz         
MEM 128M
NIC Intel Pro/100+ Management Adapter

DV receiver

 CPU Celeron 466MHz
MEM 128M
NIC Intel Pro/100+ Management Adapter

 Ethernet switch was installed to connect the sender and the receiver to the network. However, a few switches we attempted (Melco 16port SwitchingHub) failed to link up in full-duplex mode. Having replaced it to another switch (Planex 8port SwitchingHub), it succeeded to link up in full-duplex mode.　

　

Experiment of SOI project

  We tried to exchange DV-format video stream of two remote classrooms between SFC and Waseda. DV stream requires 33Mbps bandwidth per one direction. However, the received movies were bad quality because FDDI has no capacity for full-duplex 33Mbps. So we reduced their sizes to 1/10. This made the movies clear and smooth.
