Hi, I want to *add some users to the example* (the attached file), in order to simulate congestion in the network. I added one tcp and one udp users like this:
set n0 [$ns node] set n1 [$ns node] set n2 [$ns node] set n3 [$ns node] $ns duplex-link $n0 $n2 2Mb 10ms DropTail $ns duplex-link $n1 $n2 2Mb 10ms DropTail $ns duplex-link $n2 $n3 1.7Mb 20ms DropTail set tcp [new Agent/TCP] $tcp set class_ 2 $ns attach-agent $n0 $tcp set sink [new Agent/TCPSink] $ns attach-agent $n3 $sink $ns connect $tcp $sink $tcp set fid_ 1 set udp [new Agent/UDP] $ns attach-agent $n1 $udp set null [new Agent/Null] $ns attach-agent $n3 $null $ns connect $udp $null $udp set fid_ 2 $ns at 0.1 "$udp start" $ns at 1.0 "$tcp start" $ns at 4.0 "$tcp stop" $ns at 4.5 "$udp stop" 1. Is that the way to add users? 2. if I want to add another one, how much nodes I need to add, and how is the best way to link them? 3. do I need to add queue?
