2. Background-1
In 2004, the FWIS VPN Pilot Project was launched as a collaborative project between Regions II and V and eleven volunteer NMHS in the Regions participated in the project.
RA-II: China, Hong Kong, India, Japan, Republic of Korea, Saudi Arabia, Vietnam
RA-V: Australia, Brunei, Malaysia, New Zealand
The Project successfully proved that it was feasible for relatively small centers to establish a VPN link through Internet as long as they would receive appropriate technical assistance from advanced centers.

3. Background-2
Outcomes of the Project were presented to the ITT-FWIS meeting held in September 2004, Geneva.
The meeting highly appreciated the Project especially for promoting involvement of small centers in activities toward development of WIS, and it also requested to continue the Project extending to the WIS application level in cooperation with other pilot projects for WIS application components such as request/reply portal and metadata standards.

4. Concept of the Advanced Phase
To study how small Centres that have less expertise and/or less telecom infrastructures could get benefits from forthcoming advanced WIS environment to their operational purposes through Internet-VPN.

5. Major Challenges
Comprehensive and continual tests from transport level to application level
Simulation of NC operation with prototype applications supported by prototype GISC/DCPC servers.
Prototype application of data input service driven by WMO metadata and schema, and support MTDCF
Study of authorization and authentication methods for secure data reporting and providing
Possible cooperation with other Pilot Projects
Expansion of participants.

6. Outline Two years project from 2005 through 2006
13 Participants (as of 1st October 2005)
RA-II: China, Hong Kong, India, Islamic Republic of Iran, Japan, Republic of Korea, Oman, Saudi Arabia, Vietnam
RA-V: Australia, Brunei, Malaysia, New Zealand
Internet bandwidth of the participants varies from 512Kbps to 440Mbps
Beijing, Melbourne, and Tokyo act as provisional GISC/DCPC, and others act as provisional NC

7. VPN links among centers participating in the pilot project
Challenges of the VPN
Establish Permanent Internet-VPN
Establish VPN through dial-up, mobile or temporary Internet environment
Use of private IP address in the VPN
Use of IPv6 ( option)

9. SATAID
SATAID is an application program originally developed for meteorological training, especially for nephanalysis.
SATAID could display most of meteorological data, e.g. GPV, radar, profiler as well as satellite images, has many useful image analyzing capabilities, e.g. superposition, animation, cross-section, drawing contour, annotation.
SATAID has been registered on WMO VL resource library

10. An example of SATAID

11. PANDORA Server PANDORA Server is an http driven data and proxy server.
PANDORA works as one-stop data server, it forwards a request automatically if it can’t satisfy a request by itself and other PANDORA could.
PANDORA has capability of data conversion and cut off to decrease the quantity of transfer data.
PANDORA has been installed at BoM for training avtivities while inside JMA for operational purposes.

15. Utilization of IPv6
Additional collaborative IPv6 test is planned among　BoM, KMA, and JMA
Test items are being discussed among technical contacts
IPv6　Addresses
BoM : 2001:8ffff:8001::/48
KMA : 2001:
JMA : 2001:240:E5::/48

16. Progress of the Advanced Phase
Build basic system and opened the VPN-PP Web Site for VPN users (early July 2005 )
Established first VPN connection with HKO (21st July)
Opened Discussion Web Page (12th Aug)
Opened Traffic analysis Web Page (22nd Aug)
