Mininet is a container orchestration system for network emulation.
If you are using Mininet in a VM or on a physical server, it is easy to use onos.py
to start up a complete emulated ONOS network, including ONOS cluster, modeled control network, and data network.
Note: This is work in progress - if you wish to try it now, you will need to get onos.py from the following patch: https://gerrit.onosproject.org/#/c/9143/
First, make sure that you have built ONOS using buck
:
cd ~/onos
buck build onos
Next, use Mininet and onos.py
to start up a virtual ONOS cluster and data network:
cd ~/onos/tools/dev/mininet
sudo mn --custom onos.py --controller onos,3 --switch onosovs --topo torus,4,4
What does this do?
--custom onos.py
: uses onos.py
to extend Mininet with new controller and switch types
--controller onos,3
: tells Mininet to start up an ONOS controller cluster with 3 ONOS nodes
--switch onosovs
: this is currently necessary to enable Mininet to automatically connect to a controller with multiple IP addresses (you can also just use --switch onos
)
--topo torus,4,4
: tells Mininet to use a 4x4 torus topology for the data network
