<div>Hi all,</div>
<div><br>
</div>
<div>Tricircle was officially accepted yesterday as a big-tent project.</div>
<div><br>
</div>
<div>The purpose of the Tricircle project is to provide networking automation</div>
<div>across Neutron in multi-region OpenStack clouds deployment.</div>
<div><br>
</div>
<div>Use cases for the Tricircle are described in</div>
<div>https://wiki.openstack.org/wiki/Tricircle#Use_Cases.</div>
<div><br>
</div>
<div>A brief introduction of Tricircle is provided here:</div>
<div><br>
</div>
<div>Each OpenStack cloud includes its own Nova, Cinder and Neutron, the</div>
<div>Neutron servers in these OpenStack clouds are called local Neuron</div>
<div>servers, all these local Neutron servers will be configured with the</div>
<div>Tricircle Local Neutron Plugin. A seperate Neutron server will be</div>
<div>installed and run standalone as the coordinator of networking automation</div>
<div>across local Neutron servers, this Neutron server will be configured</div>
<div>with the Tricircle Central Neutron Plugin, and is called central</div>
<div>Neutron server.</div>
<div><br>
</div>
<div>Leverage the Tricircle Central Neutron Plugin and the Tricircle Local</div>
<div>Neutron Plugin configured in these Neutron servers, the Tricircle can</div>
<div>ensure the IP address pool, IP/MAC address allocation and network</div>
<div>segment allocation being managed globally without conflict, and the</div>
<div>Tricircle handles tenant oriented data link layer(Layer2) or network</div>
<div>layer(Layer3) networking automation across local Neutron servers,</div>
<div>resources like VMs, bare metal or containers of the tenant can</div>
<div>communicate with each other via Layer2 or Layer3, no matter in which</div>
<div>OpenStack cloud these resources are running on.</div>
<div><br>
</div>
<div>How to start in Tricircle: </div>
<div>1. The best entry point for the Tricircle project is its wiki page:</div>
<div>https://wiki.openstack.org/wiki/Tricircle. Source code repository is</div>
<div>https://github.com/openstack/tricircle.</div>
<div><br>
</div>
<div>2. You can play it through devstack: </div>
<div>https://github.com/openstack/tricircle/blob/master/doc/source/multi-node-installation-devstack.rst</div>
<div><br>
</div>
<div>3. The design blueprint provides general overview on the ongoing discussion</div>
<div>on the design:</div>

<div><br>
</div>
<div>We are trying to tackle common use cases and challenges in OpenStack</div>
<div>multi-region cloud area, We welcome new contributors who wish to join our</div>
<div>effort. </div>
<div><br>
</div>
<div>We are holding a weekly IRC meeting:</div>
<div> Weekly on Wednesdays at 1300 UTC, IRC channel: #openstack-meeting</div>
<div><span class="Apple-tab-span" style="white-space:pre"></span></div>
<div>Project IRC channel and other resources could be found here:</div>
<div>https://wiki.openstack.org/wiki/Tricircle#Resources.</div>
<div><br>
</div>
<div>And everyone is welcome.</div>
