Local area computer networks are well-established, and highly-interconnected, heterogeneous local networks are coming into prominence. NESTMOD is a combined analytical modeling and simulation tool, based on the existing tools NetMod and NEST, that is responsible for representing the topology of interconnected networks as well as providing library routines that describe the behavior of the interconnected networks. As an example of current technology, the metropolitan area network, DQDB (distributed queue dual bus), has been added to NESTMOD. The purpose of this paper is to describe the DQDB simulation and compare the simulation results with well-known analytical results.
