           Summary: star topologies are painful to create
           Product: ns-3
           Version: pre-release
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P3
         Component: helpers
        AssignedTo: ns-bugs at isi.edu
        ReportedBy: mathieu.lacage at sophia.inria.fr


This is especially obvious when using the BridgeNetDevice/BridgeHelper.

I would like to propose adding both methods:
std::pair<NetDeviceContainer,NetDeviceContainer> 
CsmaHelper::InstallStar (Ptr<Node> center, const NodeContainer &terminals);

std::pair<NetDeviceContainer,NetDeviceContainer> 
PointToPointHelper::InstallStar (Ptr<Node> center, const NodeContainer
&terminals);

The biggest issue with this proposal is what should be the return value of
InstallStar. As an alternative to the above proposal, we could create a
NetDeviceContainerPair class to mirror our use of std:: containers in the
helper API.
