Example Spec - The title of your RFE

Include the URL of your launchpad RFE:


Introduction paragraph – why are we doing this feature? A single paragraph of prose that deployers, and developers, and operators can understand.

Do you even need to file a spec? Most features can be done by filing an RFE bug and moving on with life. In most cases, filing an RFE and documenting your design in the devref folder of neutron docs is sufficient. If the feature seems very large or contentious, then the drivers team may request a spec, or you can always file one if desired.

Problem Description

A detailed description of the problem:

  • For a new feature this should be a list of use cases. Ensure that you are clear about the actors in each use case: End User vs Deployer. Ensure that you identify which area of the core is being affected; for something completely new, it should be clear why you are considering it being part of the core.

  • For a major reworking of something existing it would describe the problems in that feature that are being addressed.

Note that the RFE filed for this feature will have a description already. This section is not meant to simply duplicate that; you can simply refer to that description if it is sufficient, and use this space to capture changes to the description based on bug comments or feedback on the spec.

Proposed Change

How do you propose to solve this problem?

This section is optional, and provides an area to discuss your high-level design at the same time as use cases, if desired. Note that by high-level, we mean the “view from orbit” rough cut at how things will happen.

This section should ‘scope’ the effort from a feature standpoint: how is the ‘neutron end-to-end system’ going to look like after this change? What Neutron areas do you intend to touch and how do you intend to work on them? The list below is not meant to be a template to fill in, but rather a jumpstart on the sorts of areas to consider in your proposed change description.

  • Am I going to see new CLI commands? * Is OpenStack CLI covered in addition to neutronclient?

  • How do you intend to support or affect aspects like: * Address Management, e.g. IPv6, DHCP * Routing, e.g. DVR/HA * Plugins, ML2 Drivers, e.g. OVS, LinuxBridge * Agents, e.g. metadata * High level services, e.g. *-aas. * Scheduling, quota, and policy management, e.g. admin vs user rights * API and extensions * Clients * Impact on services or out-of-tree plugins/drivers

  • What do you intend to not support in the initial release?

You do not need to detail API or data model changes. Details at that level of granularity belong in the neutron devref docs.
