We introduce and discuss a methodology for heterogeneoussimulations of computer networks usingthe dynamic simulation backplane. This methodologyallows for exchanging of protocol informationbetween simulators across layers of the protocolstack. For example, the simulationist maywish to construct a simulation using the rich setof TCP models found in the ns network simulator,and at the same time using the highly detailed wirelessMAC models found in the GloMoSim simulator.The backplane provides an interface between heterogeneoussimulators which allows these simulators toexchange meaningful information across layers ofthe protocol stack, without detailed knowledge of internalrepresentation in the foreign simulator. Withthis method of heterogeneous simulation, new andexperimental protocols can be validated and tested inconjunction with existing and accepted simulations of lower protocol layers. We discuss the particular problems presented bythe split protocol stack model, and present our solutions.We give results of our implementation of thesplit protocol backplane, using the ns simulator forthe higher protocol stack layers, and the GloMoSim simulator for the lower layers.
