Why do we need the WIS?
Why do we need any Data Communication Networks?
To move data and products?
To feed processing systems?
To tell someone something?
To Improve life! By satisfying societies needs.
Hold that thought -
Providing the Highway
WIS Data Communication Network Needs
Full functionality for current requirements
Relative ease to expand functionality
Extensible virtualization
Transition to new technology
Network centric systems to provide interconnectivity
Highly scaleable architecture
Routine technology refresh
Providing the Highway
WIS Data Communication Network Needs
• IP-based networking solutions provide:− Any-to-any connectivity
− High degree of bandwidth scalability
− Optimum redundancy and survivability
− IP convergence (i.e., voice, video and data over IP)
− High-end performance
• Network security remains paramount, particularly in light of today’s socio-political threats
• Segmentation from the public Internet
• Minimizes risk of security or privacy breaches

Challenges and Opportunities for the WIS
Demand for data and prediction services has dramatically increased– Climate Services: Drought / El Niño/La Niña– Seismic data for Tsunami Warning Systems– Non traditional data sets / Mesonet Data– Extra-disciplinary (other sciences) data sets
International Data Policy: Open & unrestricted use of weather, climate and ocean data
Inter/Intra regional cooperation & programs Global Earth Observing System of Systems (GEOSS) WMO code migration DAR technologies Technology infusion: Keeping up with advances in science and
technology IPv6

New Technologies
Geographic Information Systems (GIS) Digital Audio / Video Broadcast (DAB / DVB) Optical Networks Multi Protocol Label Switching (MPLS) Wireless Public-Key Infrastructure (PKI) New Data Formats
– Table driven – Binary & XML
– Array based – HDF & NetCDF
Data discovery based exchange (DAR)

US GISC / VGISC
US WIS development planning & implementation underway Major infrastructure upgrades in process & need to be completed.
– Replacement Message Switching System
• File switching capability built into new systems
– Geographically separated , fully functional back up system
• Data synchronization via database snapshoting using Db change logs.
– Nationwide MPLS cloud
• All connectivity will transition to direct connect or a gateway connection
• Transition of connections underway
WMC / RTH Washington will provide WIS GISC functionality within its systems.
– Will have virtual extension to other centers adding to GISC functionality
– Will coordinate within Region IV to develop regional plan

Major WIS Concern
Existing GTS Frame relay contract ends Dec 2007
BT may be willing to extend for 1 year
What will be its replacement ???
MPLS ???

Data Communication NetworksThe Warehouse
GISC / VGISC – This is the new piece and the challenge– How do we support operational functions with these new
technologies?
• Currently, RTH Washington services 75 to 100 request/reply queries per day.
• How will this scale?
– Data Synchronization
– From managed network services to managed information services
– User not provider managed dissemination services via subscription and ad hoc requesting
