Netml-ns3-click: modeling of routers in Netml/ns3 by means of the click modular router

In this paper the design, development and use of a facility to run ns3 simulations, including Click routers, of networks constructed by the Netml system for analysis and design of networks in the cloud is described. The Netml system enables an XML description of a network to be converted into an ns3 program, and then runs this simulation, collecting and plotting the results, in a freely available public server at netml.org. A basic implementation of IPtables is also implemented. Users are able to specify any number of filtering rules within the forwarding chain of the filter table. This facility is implemented by generating a Click script from the rules.
