<h2 id="introduction"><a class="header" href="#introduction">Introduction</a></h2>
|
|
<p>In the previous chapter, we wrote a simulation script for a simple Ethernet network. In this chapter, we will discuss how to customize it using the attributes of the different classes used.</p>
|
|
<h2 id="attributes-in-ns-3"><a class="header" href="#attributes-in-ns-3">Attributes in ns-3</a></h2>
|
|
<p>To organize access and configuration of instantiated object parameters, ns-3 uses its own attribute system.</p>
|
|
<p>In the previous chapter, we already implemented this overlay using the “SetAttribute()” function to configure the application. This function has two arguments. The first is a string corresponding to the name of the attribute to be changed. The second is the value to be assigned to this attribute.</p>
|
|
<p>The various attributes available for each object are visible in the C++ implementation of each object. Here is an example of the EthernetChannel object described in contrib/ethernet/model/ethernet-channel.cc.</p>
|
|
<pre><code class="language-c++">TypeId
|
|
EthernetChannel::GetTypeId()
|
|
{
|
|
static TypeId tid =
|
|
TypeId("ns3::EthernetChannel")
|
|
.SetParent<Channel>()
|
|
.SetGroupName("Ethernet")
|
|
.AddConstructor<EthernetChannel>()
|
|
.AddAttribute("Delay",
|
|
"Propagation delay through the channel",
|
|
TimeValue(NanoSeconds(25)),
|
|
MakeTimeAccessor(&EthernetChannel::m_delay),
|
|
MakeTimeChecker())
|
|
.AddTraceSource("TxRxEthernet",
|
|
"Trace source indicating transmission of packet "
|
|
"from the EthernetChannel, used by the Animation "
|
|
"interface.",
|
|
MakeTraceSourceAccessor(&EthernetChannel::m_txrxEthernet),
|
|
"ns3::EthernetChannel::TxRxAnimationCallback");
|
|
return tid;
|
|
}
|
|
</code></pre>
|
|
<p>We can see that this object has only one attribute called Delay, which allows you to configure the propagation delay. It is of type Time and has a default value of 25ns.</p>
|
|
<p>Thus, it is possible to configure the propagation delay in the previous simulation script as follows:</p>
|
|
<pre><code class="language-c++"> [...]

|
|
|
//Create Ethernet Channels and connect switch to the end-stations
