Abstract

The design of network protocols is greatly acceleratedby the use of simulators particularly when studying aprotocol's behavior in a large internetwork topology.However the accuracy of the simulation results are heavilyaffected by the input network topology. As taking a realmap as an input is not always feasible, artificially createdtopologies are often used. There exist many networktopology generators available but recent discoveries onthe Internet topology have made most of them obsoletewhen it comes to model a typical part of the Internet. Thispaper presents a free open source software designed fornetwork topology analysis and modeling called networkmanipulator (nem). It is capable of creating realisticInternet - like topologies and it can check proof them on thefly by a thorough topology analysis. The paper especiallyfocuses on the architecture and the capabilities of thesoftware.
