  1. Session 1: Technology Development August 15 NSF Workshop

  2. What problems are we trying to solve… With our network simulation and modeling tools? • The primary focus is on research, including research in network management, configuration tools, congestion control, routing, security, QoS, web and other application-level infrastructures, possibly the interactions of large adaptive networks applications, etc.

  3. Multiple simulators? • It is clear that a single simulator for the network research community would not be desirable. • One of the goals is for an architecture where it is easy for researchers to add their own components. • NSF could encourage research in simulation technology to promote interoperability in network simulators.

  4. Simulation technology needs advancement.

  5. How do we increase the confidence from our results? • Validation and verification. • Increasing the critical user base. • Research results from simulators still holding when carried over to the real world.

  6. What are the properties that we want from our simulation tools? • Scalability, • Interoperability (composing elements from different simulators), • Extensibility, • Heterogeneity within the simulator, • Different layers of abstraction, • Usability.

  7. For what network research problems are simulator a useful tool? • Congestion control; • Defense about denial of service attacks, viruses, and worms; • Wireless (Manet, routing, mac protocols, transport protocols over wireless) • QoS, • Tradeoffs between security and effciency (e.g., information passed from on end to another), • Routing (Manet, MPLS-based routing). • Would simulator tools be useful for exploring replacements for BCP?

  8. Best Current Practice Scenarios • The NSF could promote the development of Best Current Practice scenarios for simulations and test-bed experiments. • After Best Current Practice scenarios for congestion control research, they could also be developed for routing research and other areas. • Evaluating the BCP scenarios includes evaluation tools with a measurement component, i.e., the distribution of connection sizes and round-trip times.
