ONOS : Open Network Operating System
What is ONOS?
ONOS is the only SDN controller platform that supports the transition from legacy “brown field” networks to SDN “green field” networks. This enables exciting new capabilities, and disruptive deployment and operational cost points for network operators.
- High availability through clustering and distributed state management.
- Scalability through clustering and sharding of network device control.
- Performance that is good for a first release, and which has an architecture that will continue to support improvements.
- Northbound abstractions for a global network view, network graph, and application intents.
- Pluggable southbound for support of OpenFlow, P4Runtime, and new or legacy protocols.
- Graphical user interface to view multi-layer topologies and inspect elements of the topology.
- REST API for access to Northbound abstractions as well as CLI commands.
- CLI for debugging.
- Support for both proactive and reactive flow setup.
- SDN-IP application to support interworking with traditional IP networks controlled by distributed routing protocols such as BGP.
- IP-Optical use case demonstration.
The following packages are required:
- python3 (needed by Bazel)
Build ONOS from source
The minimum required Bazel version is 1.0.0
- Clone the code from the ONOS Gerrit repository
$ git clone https://gerrit.onosproject.org/onos
- Optionally, you can add the ONOS developer environment to your bash profile. This will provide access to a number of handy commands to run, test and debug ONOS. No need to do this step again if you had done this before:
$ cd onos $ cat << EOF >> ~/.bash_profile export ONOS_ROOT="`pwd`" source $ONOS_ROOT/tools/dev/bash_profile EOF $ . ~/.bash_profile
- Build ONOS with Bazel
$ cd $ONOS_ROOT $ bazel build onos
Start ONOS on local machine
To run ONOS locally on the development machine, simply run the following command:
$ bazel run onos-local [-- [clean] [debug]]
Or simpler one, if you have added the ONOS developer environment to your bash profile:
$ ok [clean] [debug]
The above command will create a local installation from the ONOS tarbal
(re-building if necessary) and will start the ONOS server in the background. In
the foreground, it will display a continuous view of the ONOS (Apache Karaf) log
file. Options following the double-dash (–) are passed through to the ONOS
Apache Karaf and can be omitted. Here, the
clean option forces a clean
installation, removing any state from previous executions. The
means that the default debug port 5005 will be available for attaching a remote
Interacting with ONOS
To access ONOS UI, use a browser to open:
Or simpler, use the
onos-gui localhost command.
The default username and password is
To attach to the ONOS CLI console, run:
$ onos localhost
To run ONOS unit tests, including code Checkstyle validation, run the following command:
$ bazel query 'tests(//...)' | xargs bazel test
Or better yet, to run code Checkstyle and all unit tests use the following convenience alias:
ONOS code is hosted and maintained using Gerrit.
Code on GitHub is only a mirror. The ONOS project does NOT accept code through pull requests on GitHub.
