Resumen:
Simulation is an important tool to validate the performance impact of control decisions in Software DefinedNetworks (SDN). Yet, the manual modeling of complex topologies that may change often during a designprocess can be a tedious error-prone task. We present TopoGen, a general purpose architecture andtool for systematic translation and generation of network topologies. TopoGen can be used to generatenetwork simulation models automatically by querying information available at diverse sources, notably SDNcontrollers. The DEVS modeling and simulation framework facilitates a systematic translation of structuredknowledge about a network topology into a formal modular and hierarchical coupling of preexisting ornew models of network entities (physical or logical). TopoGen can be flexibly extended with new parsersand generators to grow its scope of applicability. This allows to design arbitrary workflows of topologytransformations. We tested TopoGen in a network engineering project for the ATLAS detector at CERN.
