The NSF Ocean Observatory Initiative Cyberinfrastructure has a real world problem with the following five key concerns:
1) Real-time global distribution of science data and metadata;
2) Coupling of observation networks with data assimilation/numerical modeling systems;
3) Managing real-time event detection and response;
4) Facilitating multi-institutional interactive research experiments; and
5) Operating for the next 30 years across multiple communities over a federated resource base at a national scale with the intent to collaborate globally.
These concerns present us with a set of six core technical challenges:
1) Real-time global connectivity to distribute science data ranging from 10^1 to 10^9 bps;
2) Demand-driven distribution of application specific functionality to targeted locations in the network;
3) Demand-driven scaling of the system at a component and location level of concern;
4) Continuous operations in the presence of failures;
5) Secure operations across multiple authority domains; and
6) Technological evolution of the infrastructure over a 30 year operational life cycle. You will hear how we’re addressing these challenges, and how our experience can be applicable to future large-scale real-time networks.
