Presentation Transcript

  1. NOAA’sNWS Telecommunication GatewayRTH Washington • Fred Branski • Office of the Chief Information Officer • NOAA’s National Weather Service • 8th APSDEU Meeting • Oct 10-12, 2007

  2. NWSTG/RTH Functional Overview • The NWSTG/RTH is • the central communication facility of the NWS; • the primary acquisition and distribution center for NWS data and products; • the primary acquisition and distribution center for international data and products to meet WMO, ICAO and bi-laterally agreed US requirements; • A major data exchange hub for NOAA and other agency data and products. • Will become Washington Global Information Systems Center (GISC) within the WMO Information System (WIS).

  3. NWSTG/RTHFunctional Overview The NWSTG includes • WMO Regional Telecommunication Hub (RTH) Washington • ICAO OPMET Databank (KWBCYMYX) • the ASOS Operations and Monitoring Center (AOMC) • Operational oversight of U.S. federal automated surface observing systems • the AWIPS Network Control Facility (NCF) • AWIPS is the main NWS’ system which supports the NWS forecast and warning mission requirement • The NCF is the central communications hub and technical support center for AWIPS

  4. Replacement & Backup NWSTG (RTG/BTG) • Full functional replacement of existing capabilities • Expanded capacity and capability • Transition to new technology • Message queuing (MQ) for internal transport • Network centric systems interconnectivity • Relational database central processing engine • NAS/SAN storage solutions • Highly scaleable architecture • Planned Hardware refresh

  5. Government Networking Requirements - NOAAnet • IP-based networking solution • 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

  6. NOAAnet Transition • NOAAnet: RTG OC-12 / BTG OC-3 (OC-12 in progress) • Customer transitions to NOAAnet: December 2006 to September 2008 • Internal underway, NWS regions done, NCF, NESDIS soon • External – direct to NOAAnet or through an Access Point • Initially two Access Points for external connectivity • One within the RTG facility but external to the infrastructure (temporary to facilitate transitions) • One in New York City– GTS, AFTN / FAA / Hawaii / Micronesia, Others? • Possibly Atlanta, Chicago, Tacoma, ??? (based on need &cost)

  42. Issues • MTN Cloud 1 Expiry • Contract end - Dec 2007 • BT interested in 1 year extension • WMO coordination meeting November 2007 • RTH Exeter – RTH Washington Link • Delays up to 5 hours • Psbl traffic shaping issue • Traffic growth expected • Should we up bandwidth up current link or wait for cloud 1 replacement?

  43. Issues • CMC – Washington Link • No problem with existing traffic on link • Plan to move NAEFS data to operational link • Psbl move of RADAR data to link • NWS/OCIO investigating cost of upgrade • Should we look at NESDIS requirement also? • WMO Information System (WIS)? • Washington GISC interaction with Asia & Euro GISCs? • Metadata catalogue coordination? • Communication requirements? • When to address this - next meeting?
