Abstract
| Varying simulation granularity allows a single simulator to
accommodate both detailed and high-level simulations. Networking
protocols are studied at many levels, both at the detail of an
individual protocol, and in the aggregation of many data ows and
interaction of many protocols. The abstraction mechanisms in ns
allow researchers to examine both of these issues without changing
simulators, and to validate abstractions by comparing detailed and
abstract results. Emulation: Most simulation experiments are con
ned to a single simulated world including only those protocols and
algorithms included in the simulator. However, emulation, which
allows a running simulator to interact with operational network
nodes, can be a powerful tool in protocol design.
