unknown flowsComputational resources on controllersNetwork

What We Have DoneBuild the network topologyReserve two nodes:
one in GPO, another in ClemsonReserve an additional node in
protoGENI to play as the controllerWe choose a protoGENI node to be
the controller since it can be dedicated ONLY for our projectWe use
flake to reserve this node and configure it as controller in
request rspec fileReserve network resources: set one datapath (VLAN
3715)
What We Have DoneInsert trafficInstall traffic generator --
iperfGenerate UDP packets
What We Have DoneObserve CPU changes on controllers (Pox)
Pox costs the majority of the CPU source300 flows in one second
can crash the Pox
Without PoxStarted PoxInsert traffic with IperfFuture PlanChange
the rate of unknown flowsChange the network topologyObserve switch
performanceNext What can we do to limit the impact of large number
of flows
