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

• 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

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 ???

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
