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.opendaylight-osgipackage/opendaylight

sudo ./run.sh

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.

1. With OpenDaylight Controller and Mininet running as described in previous sections, log into the web interface.

2. Drag and drop devices to organize the topology into its logical arrangement, then save the configuration.

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 h7PING 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 ms64 bytes from 10.0.0.7: icmp_req=2 ttl=64 time=0.054 ms64 bytes from 10.0.0.7: icmp_req=3 ttl=64 time=0.060 ms64 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 2999msrtt min/avg/max/mdev = 0.052/0.422/1.523/0.635 msmininet>

5. Click the Troubleshooting tab and then load the Flow Details for one of the switches.

6. View the Port Details.

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

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).
