Group Based Policy Service Chain Driver for One Convergence NVSD Controller

https://blueprints.launchpad.net/group-based-policy/+spec/gbp-oc-nvsd-servicechain-driver

This blueprint proposes a Group Based Policy (GBP) Service Chain driver to realize GBP Service Chain APIs with One Convergence NVSD controller.

Problem description

One Convergence NVSD controller implements an overlay fabric to provide virtual networks and enable the deployment of network services in the virtual networks. GBP Service Chain APIs define the abstractions for specifying a chain of services that can be used as a target in GBP Policy Rules. GBP Service Chain plugin framework provides the capability to use different drivers to render the Service Chain definition using a specific technology. One Convergence GBP Service Chain driver is required to implement the GBP Service Chain APIs [2] using the connectivity, policy flow and service insertion primitives provided by NVSD controller.

Proposed change

We propose the addition of a new GBP Service Chain driver to implement the GBP Service Chain APIs [2] and render the Service Chain using the NVSD controller. This driver will proxy the APIs via REST interface to the NVSD controller. The GBP Service Chain driver for NVSD controller will implement the Service Chain driver interface based on the null implementation provided in services.servicechain.drivers.dummy_driver.NoopDriver.

Alternatives

None

Data model impact

None (existing GBP Service Chain model is used)

REST API impact

None

Security impact

None

Notifications impact

None

Other end user impact

The driver will reuse the configuration for NVSD Neutron plugin [2] to access the NVSD controller.

Performance Impact

This driver should allow for a more extensive rendering of GBP Service Chain definitions using the One Convergence NVSD controller.

Other deployer impact

None

Developer impact

None

Work Items

  1. Developing the NVSD GBP Service Chain driver

Dependencies

Group Based Policy Plugin Group Based Policy Service Chain Plugin

Testing

Unit tests will be provided.

The 3rd party One Convergence CI setup will be enhanced to cover the testing of NVSD GBP Service Chain driver using the NVSD controller.

Documentation Impact

Documentation needs to be updated to reflect the addition of a new GBP Service Chain driver and it's configuration parameters.
