1. What is the problem?
Multiple north-south external network topology is supported,
but the east-west networking for local networks across multiple
OpenStack clouds has not been supported yet.

2. What is the solution to the problem?
In multi-region cloud deployment, a requirement is that each
OpenStack cloud provides external network, north-south traffic
is expected to be handled locally for shortest path, and/or
use multiple external networks to help application north-south
traffic redundancy, at the same time east-west networking of
tenant's networks between OpenStack cloud is also needed.
This path will introduce east-west gateway router to address
the east-west networking for local networks in different
OpenStack clouds.

3. What the features need to be implemented to the Tricircle
to realize the solution?
East-west gateway router.

Tricircle

The purpose of the Tricircle project is to provide networking automation across Neutron servers in multi-region OpenStack clouds deployment.

Each OpenStack cloud includes its own Nova, Cinder and Neutron, the Neutron servers in these OpenStack clouds are called local Neuron servers, all these local Neutron servers will be configured with the Tricircle Local Neutron Plugin. A separate Neutron server will be installed and run standalone as the coordinator of networking automation across local Neutron servers, this Neutron server will be configured with the Tricircle Central Neutron Plugin, and is called central Neutron server.

Leverage the Tricircle Central Neutron Plugin and the Tricircle Local Neutron Plugin configured in these Neutron servers, the Tricircle can ensure the IP address pool, IP/MAC address allocation and network segment allocation being managed globally without conflict, and the Tricircle handles tenant oriented data link layer(Layer2) or network layer(Layer3) networking automation across local Neutron servers, resources like VMs, bare metal or containers of the tenant can communicate with each other via Layer2 or Layer3, no matter in which OpenStack cloud these resources are running on.

Note: There are some our own definitions of Layer2/Layer3 networking across Neutron. To make sure what they are, please read our design documentation, especially "6.5 L2 Networking across Neutron". The wiki and design documentation are linked below.

The Tricircle and multi-region OpenStack clouds will use shared KeyStone(with centralized or distributed deployment) or federated KeyStones.
