Simulations of Large Scale Networks
model development is time consuming
- model reuse in new contexts difficult, rare
- model validation often inadequate, or ignored
- may require expertise across multiple domains
model execution is time consuming
- simulations of large complex networks (e.g., next generation Internet)
- detailed simulations of small or moderate sized networks
- analyzing infrequent or rare events
- five hours to simulate one minute of a moderate size ATM network (200 155 Mbps links, 50% utilized, 100K ev/sec)
Here, focus on techniques to
- support reuse of previously developed models in new contexts
- scaleable simulation systems for modeling large scale networks
