![Paper abstract ...
● This paper aims to investigate OpenFlow performance in a virtualized
testbed
● They used open-source virtualized controllers (Trema[5], Floodlight[6] and
NOX[7])
● Was analized how delay impacts ICMP, TCP and UDP traffic.
● They used Open vSwitch[8] as a software switch, and Mininet[9] as
emulation platform.](https://image.slidesharecdn.com/flowsim-presentation-150428184648-conversion-gate01/85/FlowSim_presentation-2-320.jpg)
