Due to a ransomware attack, the wiki was reverted to a July 2022 version. . We apologize for the lack of a more recent valid backup.
The tutorial describes how to achieve HA in OpenstackSwitching application. Basically, ONOS supports HA by building ONOS cluster. You can check how to build the ONOS cluster from the ONOS Tutorial. If you have no knowledge of ONOS clustering, we strongly recommend to go through the wiki page before you start this tutorial.
In addition to the ONOS clustering, we need to set up a proxy server for the REST API HA as below. Because the Neutron ONOS plugin does not accept multiple IP address for ONOS, we need to install a HA proxy server and set the proxy server IP address as the ONOS in ONOS ml2 plugin configuration.
As a simple proxy server, we used the HA proxy server (http://www.haproxy.org). Please refer to the document page for detail. Here we show the minimum information for the configuration.
How to install
$ sudo add-apt-repository -y ppa:vbernat/haproxy-1.5 $ sudo add-apt-repository -y ppa:vbernat/haproxy-1.5 $ sudo apt-get update $ sudo apt-get install -y haproxy
