FlowSim Simulation Assignment#2

1. FlowSim simulation
● Simulation of a switch from the paper "Performance
evaluation of OpenFlow controllers for network
virtualization", using the web browser simulator FlowSim
(flowsim.flowgrammable.org)

2. 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.

3. About the paper experiment...
● Experiment topology:
