Nuage Networks' ML2 Mechanism Driver

|
|
Adding mechanism driver in ML2 plugin for Nuage Networks
|
|
|
|
|
|
Problem description
|
|
===================
|
|
Nuage's VSP fits well via its northbound API exposure to both ML2 based mechanism
|
|
driver as well as via monolithic plugin. As nuage strive to add more features and
|
|
functionality to its monolithic plugin, it is important from other integration
|
|
point of view to also support ml2 mechanism driver framework. This is the effort
|
|
to start achieving that goal.
|
|
|
|
Proposed change
|
|
===============
|
|
In Juno release, mechanism driver will support basic L2 functionality as a
|
|
stepping stone to enhance it in later release.
|
|
It will implement CRUD APIs for network, subnets and ports. Idea is to
|
|
reuse as much of the code base from the current monolithic plugin itself and
|
|
for that reason driver class will inherit nuage plugin class as one of the
|
|
parent.

Implementation
|
|
==============
|
|
In order for mechanism driver to talk to Nuage's VSD, it will
|
|
require certain configuration to be read from the file. This is
|
|
similar approach to nuage's monolithic plugin. Along with parameters
|
|
mentioned at etc/neutron/plugins/nuage/nuage_plugin.ini, user will
|
|
have to pass reference to precreated net-partition as well. Once
|
|
https://blueprints.launchpad.net/neutron/+spec/neutron-ml2-mechanismdriver-extensions
|
|
is implemented (if at all), will add support for it in next release.
