+===============================================
+Fuel plugin for VPNaaS functionality in Neutron
+===============================================
+
+https://blueprints.launchpad.net/fuel/+spec/support-vpnaas-in-mos
+
+VPNaaS (VPN-as-a-Service) is a Neutron extension that introduces VPN feature
+set.
+VPNaaS provides multiple tunneling and security protocols with static routing.
+For now this plugin uses OpenSwan, which is an opensource IPsec implementation
+for Linux.
+
+Problem description
+===================
+
+Today multi-cloud integration is a popular topic, because very often we have
+more than one cloud and want to have connectivity  between tenants from the
+different clouds, for example, to have HA for our services on the VMs. And of
+course the most popular use case to have a VPN tunnel between your home network
+and a private network in some cloud.
+
+Proposed change
+===============
+
+Implement a FUEL plugin which will deploy IPSec service(OpenSwan) and configure
+VPNaaS functionality in Neutron and Horizon.
+
+Alternatives
+------------
+
+It also might be implemented as a part of FUEL core, but we decided to make
+it as a plugin for several reasons:
+* Community decided to separate VPNaaS and other aaS services into their own
+  project(repo), so we would do it the same way.
+* Another reason is that any new additional functionality makes a project and
+  testing more difficult, which is an additional risk for the FUEL release.
