Providing this capability in Neutron won't be hard.
As discussed previously in this thread this operation can be achieved using
a sequence of Neutron API calls.
The sequence would be pretty much the following:
1) verify network is associated with router, and router has external
gateway configured
2) create port
3) allocate floating IP
4) associate floating IP with port
You can surely implement it directly in Neutron - and there's no strong
opposition fromme.
From an architectural perspective, Neutron exposes an API for 'atomic'
operations. Composite, or orchestrated, operations, are better delegated to
an appropriate service, which, in this case, if the
nova.network.neutronv2.api module.
The argument for building this capability directly in neutron would be to
reduce the amount of API calls needed to achieve this goal.
If you want to proceed with implementing it directly in neutron, don't mind
my opinion. I am just a grumpy guy who loves to moan about pretty much
everything.

The blueprint proposed to assign auto floating IP during port creation.
Since auto floating IP is supported in nova-network, +1 to implement the
same in Neutron.
Salvatore,
Can you share with us the concerns in implementing in Neutron?
Thanks,

Hi Ofer,
Basically this operation consists in ensuring that an instance, when it's
booted, is also associated with a floating IP address, and therefore
publicly accessible.
I discussed this topic a couple months ago with another developer, but I
am now unable to find the chat in the openstack-dev IRC logs.
The bottom line is that even if this is registered as a neutron
blueprint, we are not really sure Neutron is the right place to perform
orchestration operation.
And this operation falls into this category - since it involves, creating
a port, ensuring the network for that port is associated with a router,
allocating a floating IP, and associating it with the port.
Currently all the orchestration operations are performed in the module
which configures instances networking, which is part of nova. This module
(nova.network.quantumv2.api) uses the quantum API.
I reckon this blueprint should be implemented there performing the
operations listed above.

Hi, I am interested in helping out with QE efforts on upstream
OpenStack, specifically around Neutron.
I'm trying to understand the following blueprint,can you please point me
to more detailed design
