Network Service Proposal for Diablo

Overview

This proposal is the result of discussions between several community members that had independently submitted blueprints for networking capabilities in Openstack. Those proposals included:

(List proposals here)

This page describes the resulting target services to be delivered in experiemental form in the Diablo timeframe.

Network Services Model

The diagram below describes two things:

1. The software services architecture, and the relationship of the Virtual Network Service and IPAM Service to Nova
2. The logical network architecture elements used to describe a virtual network topology in the Diablo timeframe

(diagram goes here)

Nova Refactoring and Responsibilities

It is proposed that Nova networking be refactored in two ways:

1. Combine networking capabilities in a more contained model, but do not remove support for existing options
2. Add support for the Virtual Network Service to the existing flat (static), flat (DHCP), and VLAN options

Virtual Networking Service

(This project needs a name. "Quantum" was proposed.)

The Virtual Networking Service will have the following responsiblities:

1. Provide API for managing L2 network abstraction (“virtual networks”?)
2. Provide authentication, verification, etc
3. Provide error handling
4. Decompose request (if necessary)
5. Dispatch requests to appropriate plug-in(s)
6. Resource consumption look-up service
7. Plug-in capability directory
