Status of the WIS VPN Pilot Status of the WIS VPN Pilot Project in Region II and VProject in Region II and V
Prepared for ET-WISC Geneva
Oct 11-14, 2005

Background-1Background-1• In 2004, the FWIS VPN Pilot Project was launche
d 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 A
rabia, Vietnam
– RA-V: Australia, Brunei, Malaysia, New Zealand • The Project successfully proved that it was feasibl
e for relatively small centers to establish a VPN link through Internet as long as they would receive appropriate technical assistance from advanced centers.
Background-2Background-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.
Concept of the Advanced PhaseConcept 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.
Major ChallengesMajor Challenges Comprehensive and continual tests from transport
level to application level Simulation of NC operation with prototype applicat
ions 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.
OutlineOutline
• 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
Challenges of the VPNChallenges 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

SATAIDSATAID• SATAID is an application program originally de
veloped 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
An example of SATAID
PANDORAPANDORA ServerServer• PANDORA Server is an http driven data and pr
oxy server.• PANDORA works as one-stop data server, it fo
rwards 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.

Collaboration with Collaboration with UNIDART UNIDART
• VPN-PP is collaborating with other Pilot Projects, especially UNIDART
• JMA already implemented a test Client, and going to build a server to provide data catalog which is compliant to WMO Metadata Std.

Utilization of IPv6Utilization 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
Progress of the Advanced Progress of the Advanced PhasePhase
• 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)• Established IPv6 Access (26th Aug)• Installed PPTP based VPN for mobile users
(9th Sep)• Opened Web site to non-VPN users (16th
Sep)• Opened MTSAT imagery page (22nd Sep)
Coming Soon-1Coming Soon-1
• Complete Establishing VPN Connections with All Participating Centres
• Data service with PANDORA server for the prototype application - SATAID
• Cooperate UNIDART by providing catalog and data
• Monitoring throughput of Internet-VPN• Coordinate IPv6 utilization with BoM and
KMA
Coming Soon-2Coming Soon-2• Enrich Prototype Data ( add GPV, …)• Create & Provide Data Catalog in
accordance with WMO Metadata std.• Accept Reporting data through VPN
and Convert it to TDCF• Prototype schema driven input
method, that could check major errors at input
