Wmo information System Data Communication Networks why? Fred Branski

WMO Information System Data Communication Networks WHY?

• Fred Branski

• Office of the Chief Information Officer

• NOAA’s National Weather Service

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 -

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

WIS Data Communication Network Needs

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)

WIS Data Communication Systems

• GTS

• IGDDS

• DAR

• Internet

• Radio

• Phone

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 Networks The Highway

• GTS itself – MTN & RMTN

• IGDDS – Satellite Dissemination & Collections systems

• Regional / National Networks

• Highways are often multi-lane using VPN or dedicated channels

Data Communication Networks The Trucks

• X.25

• Asynchronous

• IP / Sockets / Frame Relay /MPLS

• FTP
• Email
• Web

• DAB / DVB

• LDM

• XML

Data Communication Networks The Cargo

• Observations, Products, Watches, Warnings

• Data objects

• WMO formatted messages
• Files

• Standard formats

• GRIB, BUFR, CREX
• XML wrapped objects – may be alphanumeric text or tagged files containing ???
• NetCDF, HDF

Data Communication Networks The Grocer, the Baker, the Gingerbread Maker

• Data Collection or Production Centers (DCPC)

• Regional Specialized Meteorological Centers (RSMC)

• Numerical weather modeling centers

• National centers

• Data Archive centers

• Academic institutions

• Any global, regional or local data holding or producing center for which a need to access data from or send data to exists.

Data Communication Networks The 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

Data Communication Networks WIS

• The Highway

• GTS, IGDDS, DAR

• The Trucks

• X.25, IP (HTTP, FTP, etc) DAB, DVB, Radio, TV, phone, voice, writing

• The Cargo

• Observations, Products, Watches, Warnings
• GRIB, BUFR,

• The Grocer, the Baker, the Candlestick Maker

• Global, Regional or National data holders or producers
• DCPCs, RSMCs, National Centers,

• The Warehouse

• GISC / VGISC

Data Communication Networks WIS

• Highways, Trucks, Cargo,

• Grocers, Bakers and Candlestick Makers

• And now Warehousing

• THE INTERNATIONAL DATA TRANSPORTATION NETWORK

• Road transport systems must also handle emergency services be they police, ambulance or rescue.

• The People !!!
