  • 1. OpenDaylight, FloodLight stallation, and Example with Mininet OpenDaylight-Installation + Example with Mininet https://wiki.opendaylight.org/view/OpenDaylight_Controller:Installation Download VM with both OpenDayLight, FloodLight and Mininet http://yuba.stanford.edu/~srini/tutorial/SDN_tutorial_VM_64bit.ova user: ubuntu password: ubuntu Edit /etc/bash.bashrc Add the following line: PATH=$PATH:/var/lib/gems/1.8/gems/trema-0.3.19/objects/openvswitch/bin Mininet Sample Virtual Network Start Minit with this topology su sudo mn --topo=tree,3 --mac --switch=ovsk --controller=remote,ip=a.b.c.d where IP is the address of your VM (Remote OpenDayLight Controller VM/Server) OpenDaylight Example Start OpenDayLight cd opendaylight/opendaylight/distribution/opendaylight/target/distribution.opendaylightosgipackage/opendaylight sudo ./run.sh
  • 2. Open OpenDayLight GUI localhost:8080 user: admin password: admin Using the Simple Forwarding Application The OpenDaylight Controller includes an application called Simple Forwarding that lets you use the basic services for making forwarding decisions and install flows across all devices on the Openflow network. This application discovers the presence of a host via ARP message and installs dest-only /32 entries across all switches in the network, with the corresponding output ports toward the host.
  • 3. 1. With OpenDaylight Controller and Mininet running as described in previous sections, log into the web interface.
  • 4. 2. Drag and drop devices to organize the topology into its logical arrangement, then save the configuration.
  • 5. 3. Click the Add Gateway IP Address button (shown above) and add the IP and subnet of 10.0.0.254/8 4 Confirm that hosts are now reachable from one another. On the console where Mininet is running, have one host ping another. mininet> h1 ping h7 PING 10.0.0.7 (10.0.0.7) 56(84) bytes of data. 64 bytes from 10.0.0.7: icmp_req=1 ttl=64 time=1.52 ms 64 bytes from 10.0.0.7: icmp_req=2 ttl=64 time=0.054 ms 64 bytes from 10.0.0.7: icmp_req=3 ttl=64 time=0.060 ms 64 bytes from 10.0.0.7: icmp_req=4 ttl=64 time=0.052 ms --- 10.0.0.7 ping statistics --4 packets transmitted, 4 received, 0% packet loss, time 2999ms rtt min/avg/max/mdev = 0.052/0.422/1.523/0.635 ms mininet>
  • 6. 5. Click the Troubleshooting tab and then load the Flow Details for one of the switches.
  • 7. 6. View the Port Details.
  • 8. FloodLight Example Start FloodLight cd floodlight ./floodlight.sh Note: use the same previous Mininet Virtual network sudo mn --topo=tree,3 --mac --switch=ovsk --controller=remote,ip=a.b.c.d Open OpenDayLight GUI localhost:8080/ui/index.html
  • 9. Sample FloodLight Java Application Avior is an application built outside of floodlight that gives network administrators a graphical user interface to support their needs. Avior eliminates dependency on using python scripts or viewing the restAPI in order to monitor or manipulate the network. Download from: http://openflow.marist.edu/avior Enter IP of the remote controller (i.e. machine running FloodLight).
  • 10. Controller Information Switch Information
  • 11. Hosts/Servers Information Flow Manager Sample Application
  • 12. Firewall Sample Application Also available, a QoS Java Application: https://github.com/wallnerryan/floodlight-qos-beta
