2. Networked vs. Individual Radar NEXRAD = 5 min between
updates Multi-Doppler scan Surveillance scan Closest radar CASA = 1
min between updates 4-times bandwidth requirement from CASA
network
3. Closed-loop Network is critical!
4. Example Operations
5. Dynamically Allocated Resources Network and compute
resources not always required It is a clear day in Dallas today!
Allocate network resource when and where needed Software Defined
Networks and Cloud Computing suite this approach well
6. Dynamically Allocated Resources for Short-term Forecasts
(aka Nowcast) Detect Weather Forecast Detection Initiate Nowcast in
the cloud Allocate network and cloud resources Shut down Nowcast
Release network and cloud resources Run during weather event
7. US Ignite and GENI High bandwidth, low-latency networks +
GENI testbeds = Layer 2 + SDN + Open Clouds + at scale Perfect
infrastructure for our application! All comes together in DFW Urban
Demonstration Testbed
8. SDN based on Weather SDN Controller Command &
ControlForecast Detection
