Bessie: Portable Generation of Network Topologies for Simulation
Widespread use of computer networking has resulted in considerable
attention being paid to a variety of network-related problems, the
generation of efficient multicast trees being one. While many
algorithms for generation of multicast trees have been proposed, their
relative effectiveness is difficult to assess. Some algorithms have
never been implemented. Many have been simulated, but often using
ad-hoc networking modeling and simulation tools, without consistent
parameters, making direct comparisons difficult.
In this paper, we discuss a network topology generation tool named
Bessie, written entirely in Java. Bessie generates descriptions of
random point-to-point and hierarchical networks, based on
user-specified statistical parameters. We introduce modification to
Waxman's  parameters, commonly used in grid-based network topology
generators, which eliminates undesirable increases in node degree as
the number of nodes in a network increases. The modification improves
on proposed fixed scale factors.
