Overview

VPNaaS (VPN-as-a-Service) is a Quantum extension that introduces VPN feature set.

The following is the proposed plan for design and implementation of the VPN as a Service feature in OpenStack Networking for the Havana release. While our long term goal for VPNaaS is to make it very feature rich and to support multiple tunneling,security protocols that supports both static and dynamic routing, but for the short term we would want to deliver a basic experimental reference implementation based on opensource for IPsec based VPNs using just static routing that will allow us to evaluate the API, resource model and usability of this feature. This will allow us to gather feedback, and make enhancements if required.

Also we would like to have a simple model such as the AWS for configuring the VPN. In AWS the IKE and IPsec Policies are pre-defined, but we would want to make it more user configurable rather than pre-defined templates.

Again for simplicity we will be just implementing IKE with “PSK” authentication mode rather than using certificates. In future we can extend to support certificate based authentication.


Current Proposed API for VPNaaS "Quantum/VPNaaS/API"

This section describes commands that will be introduced into python-quantumclient in order to support VPNaaS advanced service.

REST API

High-Level Task Flow

The high-level task flow for using VPNaaS API to configure IPsec VPN is as follows:

  • The tenant creates a VPNService, without any connections.
  • The tenant creates one or more IKEPolicies.
  • The tenant creates one or more IPsecPolicies.
  • The tenant creates one or more VPNServiceConnections and associates with the VPNService id, IKEPolicy id and IPsecPolicy id.
