Goals¶
[explanation]
Configuration¶
This configuration is based on step 10.
This step uses the following network:
network TopologyChange

types:
channel PppLink100M extends DatarateChannel
{
delay = 5us;
datarate = 100Mbps;
}
channel PppLink10M extends DatarateChannel
{
delay = 5us;
datarate = 10Mbps;
}
