Problems in Networking in Loess Highlands

•Few global IP addresses in countryside.

-> IPv6

•Connection between IPv6 networks.

-> IPv6 on 6-to-4 on openvpn on IPv4

•How authenticate servers and clients.

-> Grid Computing with GLOBUS Security Infrastructure

Connection of IPv6 local networks

Some routers cannot transfer 6to4 packets

•Position of certification files for field servers /server-A/etc/grid-security/ /server-B/etc/grid-security/ /server-C/etc/grid-security/ …….

•Switch of certificates by chroot command /server-A/etc/grid-security/ “chroot /server-A” is accessed as if it were in /etc/grid-security/

Future Plan

•Introduction of Metbroker.

•Monitoring of septic tank system.

•Locate field servers in forestation fields.

•Design and localization of forestation and agriculture logging system.

•Locate camera servers in temples for culture promotion.

•Data collected through IPv6 GLOBUS are presented in a html page in a server in Beijing.

•Camera server monitoring septic plant in Yulin College, Shaanxi (IPv6 only)

•Field server monitoring experimental field in Yulin College, Shaanxi (IPv6 only)

http://crec.biogrid.cn/fs

•Data is collected through IPv6 Grid-FTP from Loess Highland to Beijing.

•Renewal every 5 minutes.

•The specimen is demonstrated on Jan. 28th 16:20 CST 2004.

•Monitoring the septic plant by a LAN camera.

Please scroll down the page.

•Monitoring temperature of experimental field by field server.

•17 degree Celsius.

Please scroll down the page.

•Monitoring the network speed from Loess Highlands to Beijing.

•43.13 KB/s with IPv6 over 6-to-4 over openvpn.

•48.45 KB/s with openvpn.

•53.26 KB/s with IPv4.

•ca 20% overhead by IPv6.
