Refactor P4Runtime subsystem to implement async connection procedure

This patch is an attempt to solve issues observed when restarting both
switches and ONOS nodes. Most of the issues seemed to depend on a
brittle mastership handling when deploying the pipeline.

With this patch, GDP registers devices to the core with available=false
(i.e. offline) and marks them online only when the P4 pipeline has been
deployed to the device. A new PiPipeconfWatchdogService takes care of
deploying pipelines and producing event when devices are ready.

Moreover, we fix a race condition where pipeconf-related behaviors
were not found. This was caused by GDP enforcing the merged
driver name in the network config, while external entities (e.g.
Mininet) were pushing a JSON blob with the base driver name. This patch
removes the need to rely on such a trick and instead uses
pipeconf-aware logic directly in the driver manager (change #19622).

Finally, we fix issues in P4RuntimeClientImpl that were causing the
stream channel not detecting unreachable devices. The solution is to
follow gRPC APIs and re-instantiate a new channel once the first fails.

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.

Top-Level Features

  • 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 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.

Getting started

Dependencies

The following packages are reuqired:

  • git
  • zip
  • curl
  • unzip
  • python2.7
  • Oracle JDK8

To install Oracle JDK8, use following commands (Ubuntu):

$ sudo apt-get install software-properties-common -y && \
  sudo add-apt-repository ppa:webupd8team/java -y && \
  sudo apt-get update && \
  echo "oracle-java8-installer shared/accepted-oracle-license-v1-1 select true" | sudo debconf-set-selections && \
  sudo apt-get install oracle-java8-installer oracle-java8-set-default -y

Build ONOS from source

  1. Clone the code from ONOS gerrit repository
$ git clone https://gerrit.onosproject.org/onos
  1. Add ONOS developer environment to your bash profile, 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
  1. Build ONOS with Buck
$ cd $ONOS_ROOT
$ onos-buck build onos [--show-output]

ONOS currently uses a modified version of Buck (onos-buck), which has been packaged with ONOS. Please use this version until our changes have been upstreamed and released as part of an official Buck release.

This will compile all source code assemble the installable onos.tar.gz, which is located in the buck-out directory. Note the --show-output option, which can be omitted, will display the path to this file.

Start ONOS on local machine

To run ONOS locally on the development machine, simply run the following command:

$ onos-buck run onos-local [-- [clean] [debug]]

or simplier one:

$ ok [clean] [debug]

The above command will create a local installation from the onos.tar.gz file (re-building it 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 of ONOS and the debug option means that the default debug port 5005 will be available for attaching a remote debugger.

Interacting with ONOS

To access ONOS UI, use browser to open http://localhost:8181/onos/ui or use onos-gui localhost command

The default username and password is onos/rocks

To attach to the ONOS CLI console, run:

$ onos localhost

Unit Tests

To run ONOS unit tests, including code Checkstyle validation, run the following command:

$ onos-buck test

Or more specific tests:

$ onos-buck test [buck-test-rule]

Contributing

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.

To contribute to ONOS, please refer to Sample Gerrit Workflow. It should includes most of the things you'll need to get your contribution started!
