ABSTRACT
Parallel and distributed simulation tools are emerging
that offer the ability to perform detailed, packet-level
simulations of large-scale computer networks on an
unprecedented scale. The state-of-the-art in large-scale
network simulation is characterized quantitatively. For
this purpose, a metric based on the number of Packet
Transmissions that can be processed by a simulator per
Second of wallclock time (PTS) is used as a means to
quantitatively assess packet-level network simulator
performance. An approach to realizing scalable network
simulations that leverages existing sequential simulation
