The energy consumption of a link depends directly on its current traffic load. Specify that consumption in your
platform file as follows:
- \verbatim
+ @verbatim
<link id="SWITCH1" bandwidth="125Mbps" latency="5us" sharing_policy="SHARED" >
<prop id="watt_range" value="100.0:200.0" />
<prop id="watt_off" value="10" />
</link>
- \endverbatim
+ @endverbatim
The first property means that when your link is switched on, but without anything to do, it will dissipate 100 Watts.
If it's fully loaded, it will dissipate 200 Watts. If its load is at 50%, then it will dissipate 150 Watts.
