Gluon Neutron ML2 Plugin

This story is to develop a Gluon ML2 Driver (core plugin) such that:

• Gluon Wrapper ML2 Driver subclasses ML2 Driver
• If it is Proton port, sends to Proton
• Otherwise, goes to normal ML2 driver

Dummy network, subnets etc. object will be used by Gluon ML2 driver to satisfies Nova-Neutron relationship.

Backend SDN controllers will create network, subnets etc. in our desired way.

South Bound stays the same etcd to communicate via Shim Layers with SDN Controllers so that

• Gluon ML2 core plugin will connect with etcd to determine port ownership
• Contrail will use existing plugin/mechanism driver, which is at the same level as etcd.
• Contrail’s mechanism driver needs to work with Gluon ML2 Core Plugin

The steps of exploring Gluon ML2 Core Plugin are:

• Experiment with wrapping / sub-classing method

• If successful, done

• If not successful, we try to fix ML2 by working with Neutron ML2 team

• If successful, done

• If not successful, we will use Original Gluon Model, i.e. Nova-Gluon-Neutron

• Customization for commercial deployment
