Why do we need the WIS?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.

WIS Data Communication Network Needs
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

US GISC / VGISCUS 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

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
