Question

Is it possible to create PointToPointDumbbell in ns3 but have different applications on the left nodes such as OnOffApplication, UdpClientServer, and so on

Answer 1

Yes, this is possible.

Begin by creating the dumbbell topology using PointToPointDumbbellHelper. Next, use the GetLeft(uint32_t) and GetRight(uint32_t) to get the individual Nodes on each side of the dumbbell.

Simply install the application you want on that Node using Node::InstallApplication(Ptr<Application>) or using OnOffHelper::Install(Ptr<Node>) (or the Helper for whatever application it is you want to install).
