===============================
|

|

Tricircle is a project for [Openstack cascading solution](https://wiki.openstack.org/wiki/OpenStack_cascading_solution), including the source code of Nova Proxy, Cinder Proxy, Neutron L2/L3 Proxy, Glance sync manager and Ceilometer Proxy(not implemented yet).

Important to know
|
||||
-----------
|
||||
* Only about 15k code lines developed for OpenStack cascading.
|
||||
* The initial source code is for PoC only. Refactory will be done constantly to reach OpenStack acceptance standard.
|
||||
* DVR-Patch for IceHouse: the PoC source code is based on IceHouse version, while Neutron is a master branch snapshot on July 1, 2014 which include DVR feature, not IceHouse version. The Neutron code is download from github when it was still in the developement and review status. The source code of DVR part is not stable, and not all DVR features are included, for example, N-S functions not ready.
|
||||
* DVR-Patch is the majority source code in the repository, about 180k. The patch will be remove if OpenStack cascading is developed base on Juno.
|
||||
* The Neutron cascading using the feature of provider network. But horizon doen't support provider network very well. So you have to use Neutron CLI to create a network. Or set default provide network type to VxLAN, or remove "local", "flat", "VLAN", "GRE" network typedriver from ML2 plugin configuration.
|
||||
* For Neutron L2/L3 features, only VxLAN/L3 across casacaded OpenStack supported in the current source code. VLAN2VLAN, VLAN2VxLAN and VxLAN2VxLAN across cascaded OpenStack also implemented with IceHouse version but the patch is not ready yet, source code is in the VLAN2VLAN folder.
|
||||
* The tunneling network for cross OpenStack piggy data path is using VxLAN, it leads to modification on L2 agent and L3 agent, we will refactory it to using GRE for the tunneling network to reduce patch for Juno version.
|
||||
* If you want to experience VLAN2VLAN, VLAN2VxLAN and VxLAN2VxLAN across cascaded OpenStack, please ask help from PoC team member, see the wiki page [Openstack cascading solution](https://wiki.openstack.org/wiki/OpenStack_cascading_solution) for contact information.
|
||||
* The source code now based on Juno is for PoC only. Refactory will be done constantly to reach OpenStack acceptance standard.
|
||||
* The Neutron cascading using the feature of provider network. But horizon doen't support provider network very well. So you have to use Neutron CLI to create a network.
|
||||
* Support L2 networking(VxLAN) across cascaded OpenStack, but only p2p remote host IP tunneling supported now.L2 networking through L2GW to reduce population traffic and simplify networking topology will be developed in the near future.
|
||||
* The L3 networking across casacaded OpenStack will set up tunneling network for piggy data path, useing GRE tunneling over extra_route to brige the router in different cascaded OpenStack.Therefore, the loca L2 network (VLAN,VxLAN) in one cascaded OpenStack can reach L2 network(VLAN,VxLAN) located in another cascaded OpenStack.
|
||||
* Glance cascading using Glance V2 API. Only CLI/pythonclient support V2 API, the Horizon doesn't support that version. So image management should be done through CLI, and using V2 only. Otherwise, the glance cascading cannot work properly.
|
||||
* Glance cascading is not used by default, eg, useing global Glance by default. If Glance cascading is required, configuration is required.
|
||||
* Refactory the Tricircle source code based on Juno version will be started soon once the Juno version is available.

- the cascading OpenStack needs two node, Node1 and Node 2. Add Node1 to AZ1, Node2 to AZ2 in the cascading OpenStack for both Nova and Cinder.

Make sure the 3 OpenStack can work independently before cascading introduced, eg. you can boot VM with network, create volume and attach volume in each OpenStack. After verify that 3 OpenStack can work independently, clean all created resources VM/Volume/Network.

After all OpenStack installation is ready, it's time to install IceHouse pathces both for cascading OpenStack and cascaded OpenStack, and then replace the Nova-Compute/Cinder-Volume/Neutron OVS-Agent/L3-Agent to Nova Proxy / Cinder Proxy / Neutron l2/l3 Proxy.
