Mininet Commands:

1. TCP/UDP Traffic Tests

a. Setup the Topology with xterms options (open terminal for each Node)

Alt text

sudo mn --controller=remote,ip=127.0.0.1 --mac -i 10.1.1.0/24 --switch=ovsk,protocols=OpenFlow13 --topo=linear,4  -x

a. TCP Traffic Test between h1 to h4

Run IPERF TCP Server in h4

iperf -s

RUN IPERF TCP Client in h1

iperf -c 10.1.1.4 -i 10 -t 30
iperf -c 10.1.1.4 -i 10 -P 10 -t 30

b. UDP Traffic Test between h1 to h4

Run IPERF UDP Server in h4

iperf -s -u

RUN IPERF UDP Client in h1

iperf -c 10.1.1.4 -b 10m -i 10 -t 30
iperf -c 10.1.1.4 -b 10m -i 10 -P 10 -t 30

2. Torus Topology

Torus Topology is mesh interconnect with nodes arranged in a rectilinear array of N = 3, or more dimensions 3,3 = 3 Rows and 3 columns (Matrix) of Nodes and Switches, and inter connected.

This topology forms a Loop.

sudo mn --controller=remote,ip=127.0.0.1 --mac -i 10.1.1.0/24 --switch=ovsk,protocols=OpenFlow13 --topo=torus,3,3
