In contrast to small-scale experimental methods (e.g., running a single modified Tor client or router), emulating
the entire Tor network at near-scale enables experiments that capture whole network effects. For example,
one could investigate the performance of a new router selection
scheme when all clients or routers adopt the new scheme, rather
than just a few controlled by the experimenter.
