  1. WMO Information SystemData Communication NetworksWHY? Technical Conference on the WMO Information System (TECO-WIS) Seoul, Republic of Korea, 6-8 November 2006 • Fred Branski • Office of the Chief Information Officer • NOAA’s National Weather Service

  2. 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 -

  3. 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

  4. 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

  5. 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

  6. 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)

  7. GTS IGDDS DAR Internet Radio Phone Domestic Networks Television Radio Internet Phone SBN/NOAAPORT WIS Data Communication Systems International National

  8. Other Agencies National Dissemination and Distribution Example - US NESDIS Commercial Specialized Satellite GOES Satellite Legend: Imagery Customers EMWIN NOAAPORT • Commercial Weather Services EMWIN • Research Institutions NWWS • FAA, etc. FOS WMO (> 1 min) ISCS SBN/NOAAPORT • GOES • NCEP Product Suite Local Customers ICAO • Observations Telecommunications Operations Center NWWS NCEP NWSTG (10 sec) Media & Other LDAD Customers NCF WAN Data Servers Private line Internet-Based Field Dissemination Dissemination Offices WSR-88D GTS EMWIN NWR Public

  9. 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

  10. NOAANet BackboneSprint Peerless IP Network Map Tacoma Chicago New York Cheyenne Stockton Pennsauken, NJ San Jose Relay, MD Kansas City DC Anaheim Atlanta Fort Worth External Access Point OC48/192 Possible External Access Point External Access Point (for transition only) Internet Transport Node

  11. 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 ???

  12. Data Communication NetworksThe Highway • GTS itself – MTN & RMTN • IGDDS – Satellite Dissemination & Collections systems • Regional / National Networks • Highways are often multi-lane using VPN or dedicated channels

  13. Data Communication NetworksThe Trucks • X.25 • Asynchronous • IP / Sockets / Frame Relay /MPLS • FTP • Email • Web • DAB / DVB • LDM • XML

  14. Data Communication NetworksThe 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

  15. Data Communication NetworksThe 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.

  16. 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

  17. Data Communication NetworksWIS • 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

  18. Data Communication NetworksWIS • 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 !!!

  19. Data pull Data push WIS DATA-COMMUNICATIONS FUNCTIONS AND SERVICES How do we serve the People? DAR WIS HAZ-NET VPN GTS IGDDS WIS/GTS: for time and operation-critical data & products WIS/IGDDS: for space-based data & products WIS/DAR: data discovery, access and retrieval
