Location of Queue in ns3

[Chinmay Naik]

Hello, I have a Ptr<Node> and want to install QueueDisc on it for which I need a NetDevice.

The way to create I have found out is the following :

    PointToPointHelper p2ph;
    p2ph.SetDeviceAttribute("DataRate", DataRateValue(DataRate("1000Mb/s")));
    p2ph.SetDeviceAttribute("Mtu", UintegerValue(2500));
    p2ph.SetChannelAttribute("Delay", TimeValue(Seconds(0.005)));
    NetDeviceContainer internetDevices;
    internetDevices.Add( p2ph.Install(pgw, remoteHost));

     

And then install the queueing discipline using

   TrafficControlHelper tch;
    tch.SetRootQueueDisc("ns3::CoDelQueueDisc");
    QueueDiscContainer queueDiscs;
    queueDiscs = tch.Install(internetDevices);

Now when I write : Ptr<QueueDisc> q1 = queueDiscs.Get(0); will I get the queue on the device or on the point to point link ?

 If the queue is on the link, can you guide me how to obtain the queue on a device ?
