<b>Subject:</b> [openstack-dev] [neutron] How should edge services APIs integrate into Neutron?<o:p></o:p></span></p>
</div>
<p class="MsoNormal"><o:p> </o:p></p>
<div>
<p class="MsoNormal">There's been talk in VPN land about new services, like BGP VPN and DM VPN. I suspect there are similar things in other Advanced Services. I talked to Salvatore today, and he suggested starting a ML thread on this...<o:p></o:p></p>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Can someone elaborate on how we should integrate these API extensions into Neutron, both today, and in the future, assuming the proposal that Salvatore has is adopted?<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I could see two cases. The first, and simplest, is when a feature has an entirely new API that doesn't leverage off of an existing API.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">The other case would be when the feature's API would dovetail into the existing service API. For example, one may use the existing vpn_service API to create the service, but then create BGP VPN or DM VPN connections for that service, instead
of the IPSec connections we have today.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">If there are examples already of how to extend an existing API extension that would help in understanding how to do this.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I see that there are RESOURCE_ATTRIBUTE_MAPs with the information on the API, and I see that the plugin has a supported_extension_aliases, but beyond that, I'm not really sure how it all hooks up, and how to extend an existing extension.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I'm assuming that the python-neutronclient would also need to be updated.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">So... the intent here is to start some discussion on how we do this, such that we have some things figured out before the summit and can save some time.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Thanks in advance,<o:p></o:p></p>
