  • Topology Helpers: Previously, topology helpers such as a point-to-point star existed in the +PointToPointHelper class in the form of a method (ex: PointToPointHelper::InstallStar). These topology +helpers have been pulled out of the specific helper classes and created as separate classes. Several +different topology helper classes now exist including PointToPointStarHelper, PointToPointGridHelper, +PointToPointDumbbellHelper, and CsmaStarHelper. For example, a user wishes to create a +point-to-point star network:
    +Before: +
    +NodeContainer hubNode;
+NodeContainer spokeNodes;
+hubNode.Create (1);
+Ptr hub = hubNode.Get (0);
+spokeNodes.Create (nNodes - 1);
