You can either use the measurement table (not sure if there are some further restrictions that will not allow you to do so) or some other data structure (if it is a better fit for what you would like to do).

Your application will need to get access to the forwarder and strategy instance of this node. You can probably do something like the following to make things work (not sure if this exact code snippet compiles — please verify that it actually works):

// Get the node by name
ns3::Ptr<ns3::Node> node = ns3::Names::Find<ns3::Node>(“name-of-the-node”);
// Get the forwarder instance of the node
auto forwarder = node->GetObject<ns3::ndn::L3Protocol>()->getForwarder());

Hope that this helps,
