Re: [openstack-dev] [neutron][AdvancedServices] Confusion about the solution of the service chaining!

2015-01-14 Thread Yuriy.Babenko
Hi,
we really like the idea to address the SFC use-case in Neutron working group.
We would be happy to work with the community to work out the way to consume 
service-chains via standardized neutron-api and provide use-cases and 
blueprints.
Some initial ideas on the use-case can be found in the following etherpad [1].

Keshava, we think that it would be ideal to have two type of use-cases: one 
which you described below (“dynamic” one) with the usage of IETF-defined header 
but also one “static” one where the whole chain can be pre-provisioned by the 
orchestrator via Neutron-API  w/o usage of classifier and header extensions.

Kind regards/Mit freundlichen Grüßen

solution of the service chaining!

Yes, I agree with Kyle decision.

First we should define what is Service.
Service is within OpenStack infrastructure ? or Service belongs  to NFV 
vNF/Service-VM ?
Based on that its Chaining needs to be defined.
If it is chaining of vNFs(which are service/set of services)  then it  will be 
based on ietf  ‘service header insertion’ at the ingress.
This header will have all the set services  that needs to be executed  across 
vNFV, will be carried in each of the Tennant packet.

So it requires coordinated effort along with NFV/Telco  working groups.

Service chaining isn't in the plan for Kilo [1], but I expect it to be 
something we talk about in Vancouver for the Lxxx release. The NFV/Telco group 
has been talking about this as well. I'm hopeful we can combine efforts and 
come up with a coherent service chaining solution that solves a handful of 
useful use cases during Lxxx.

Thanks,
Kyle

Yes, the above two blueprints have been implemented and are available
for consumption today as a part of the Group-based Policy codebase and
release. The GBP model uses a policy trigger to drive the service
composition and can accommodate different rendering policies like
realization using NFV SFC.

 We are developing the service chaining feature, so we need to know which one
 is the neutron's choice.

It would be great if you can provide feedback on the current
implementation, and perhaps participate and contribute as well.

 Are the blueprints about the service insertion,
 service chaining and traffic steering list in JunoPlan all Abandoned ?


Some aspects of this are perhaps a good fit in Neutron and others are
not. We are looking forward to continuing the discussion on this topic
on the areas which are potentially a good fit for Neutron (we have had
this discussion before as well).
