Improve scalability of P4Runtime subsystem The P4Runtime client was hanging (deadlock) on a master arbitration request. As such, all other requests (e.g. table write) were waiting for the client's request lock to become available. Apart from fixing those deadlocks, this patch brings a number of improvements that all together allow to run networks of 100+ P4Runtime devices on a single ONOS instance (before only ~20 devices) Includes: - Asynchrounous mastership handling in DevicHandshaker (as defined in the P4Runtime and OpenFlow spec) - Refactored arbitration handling in the P4RuntimeClient to be consistent with the P4Runtime spec - Report suspect deadlocks in P4RuntimeClientImpl - Exploit write errors in P4RuntimeClient to quickly report channel/mastership errors to upper layers - Complete all futures with deadlines in P4Runtime driver - Dump all tables in one request - Re-purposed ChannelEvent to DeviceAgentEvent to carry also mastership response events - Fixed IntelliJ warnings - Various code and log clean-ups Change-Id: I9376793a9fe69d8eddf7e8ac2ef0ee4c14fbd198
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.
The following packages are reuqired:
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
$ git clone https://gerrit.onosproject.org/onos
$ cd onos $ cat << EOF >> ~/.bash_profile export ONOS_ROOT="`pwd`" source $ONOS_ROOT/tools/dev/bash_profile EOF $ . ~/.bash_profile
$ 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.
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.
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
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]
