i wanted to count number of UDP packets that achieve to switch using pox and openflow.
this is the topology that i use:
#!/usr/bin/python

net = Mininet( controller=Controller, link=TCLink, switch=OVSKernelSwitch )
print "*** Creating nodes"

net.addLink(s2, h6)
net.addLink(s2, h4)
net.addLink(s2, h5)
print "*** Starting network"
net.build()
c1.start()
s2.start( [c1] )
print "*** Running CLI"
CLI( net )
print "*** Stopping network"
net.stop()

setLogLevel( 'info' )
topology()
i want to count the number of udp packets that "h4" sends to server through the switch and also the number of udp packets that "h5" sends to server through switch.
