Hi Carlos,

We have just started looking at the same issues you have mentioned. Please
follow the email thread started by me earlier today ([openstack-dev]
[neutron][policy] Using network services with network policies). We will be
spending more time on these topics during our upcoming weekly IRC calls as
well.

Best,

-Mohammad

Subject:	[openstack-dev] [Neutron] Group Policy questions



Hi,

I’ve a couple of questions regarding the ongoing work on Neutron Group
Policy proposed in [1].

1. One of the described actions is redirection to a service chain. How do
you see BPs [2] and [3] addressing service chaining? Will this BP implement
its own service chaining mechanism enforcing traffic steering or will it
make use of, and thus depending on, those BPs?

2. In the second use case presented in the BP document, “Tired application
with service insertion/chaining”, do you consider that the two firewalls
entities can represent the same firewall instance or two running and
independent instances? In case it’s a shared instance, how would it support
multiple chains? This is, HTTP(s) traffic from Inet group would be
redirected to the firewall and then passes through the ADC; traffic from
App group with destination DB group would also be redirected to the very
same firewall instance, although to a different destination group as the
chain differs.

Thanks.

Cheers,
Carlos Gonçalves
