Abstract
We introduce and discuss a methodology for heterogeneous
simulations of computer networks using
the dynamic simulation backplane. This methodology
allows for exchanging of protocol information
between simulators across layers of the protocol
stack. For example, the simulationist may
wish to construct a simulation using the rich set
of TCP models found in the ns network simulator,
and at the same time using the highly detailed wireless
MAC models found in the GloMoSim simulator.
The backplane provides an interface between heterogeneous
simulators which allows these simulators to
exchange meaningful information across layers of
the protocol stack, without detailed knowledge of internal
representation in the foreign simulator. With
this method of heterogeneous simulation, new and
experimental protocols can be validated and tested in
conjunction with existing and accepted simulations of lower protocol layers. We discuss the particular problems presented by
the split protocol stack model, and present our solutions.
We give results of our implementation of the
split protocol backplane, using the ns simulator for
the higher protocol stack layers, and the GloMoSim simulator for the lower layers.
