Mininet Partial Finishing

Today, we finally finished finishing the mininet part.

First of all, this section is divided into two elements, one is a custom topology, and the other is a custom flow table.

1. Open Ubuntu.

2. Create a new terminal and enter Java-jar Target/floodlight.jar to start the floodlight service. You can open the UI side of the Web page to view topologies and hosts.

3. Create a new terminal, enter the./pox/pox.py Forwarding.hub to start the Monitoring setup link. The Pox controller can release the flow meter to the openflow switch. Forwarding.hub This component adds a flood wildcard rule to each switch, which is equivalent to the Ethernet hub.

4. Create a new terminal, first verify that the Mininet custom topology can communicate with each other.

Code: sudo Python run.py. Establish a simple topological structure

Mininet>pingall; can see that each host can communicate with each other.

5. Verify that the streaming table can be customized for communication. If connection refused, first set up pox monitoring.

Code: sudo python flow1.py; display write to three flow table rules.

sudo mn--topo single,3--controller=remote--ip=127.0.0.1;

mininet>pingall; can see not ping pass.

However, according to the flow table rules, forwarding to host 1 can be ping-pass, the rest is discarded.

That is H2/H3 PING-C3 H1 can succeed.

And it should be noted that the forwarding time is significantly reduced, it should be stipulated that there is no default forwarding delay after the exit.
