Open Stack

Hi Sumit,

Thanks for comments.

We want to bring-in more flexibility for Tenants to choose from multiple vendors and their appliances for NFV using Quantum. We are in the process of expanding this to support L3 mode based on the configuration, and as well add more open source application NFVs  similar to HAProxy.

As NFV is gaining momentum, Quantum has to support VM form-factor for NFV appliances along with service provider abstractions.

Regards,
Balaji.P

Subject: Re: [openstack-dev] [Quantum]Network Function Virtualization using OpenStack and Network Service Chain Implementation Blue-Print

We had a discussion on the topic of service chaining and insertion during the summit. You can find the details here:
Etherpad: https://etherpad.openstack.org/Quantum_Services'_Chaining_and_Insertion
Blueprint: https://blueprints.launchpad.net/quantum/+spec/quantum-services-insertion-chaining-steering

My first impression on quickly browsing through your attached document is that it focuses on the service provider abstractions and might be complementary to what we discussed in the above proposal during the summit. That said, it seems to me that your document makes an assumption that a service chain always manifest as a single multiservice appliance in a VM form-factor and in a single insertion mode. This is one valid use case, however the model should not be limited to this. One can have a combination of services in different insertion modes and realized on dedicated hardware or in software. Please the aforementioned blueprint/spec for such examples and a flexible model which captures this.

Thanks,
~Sumit.

This is in continuation with the APIs I have shared couple of weeks ago in this link.

Balaji,
  Glad to see the document coming along.
I suggest we create a google doc so that it is easy to collaborate with the openstack community.

Thanks,

Hi,

It is glad to inform that we are publishing the Blue-Print for Network Function Virtualization using OpenStack and Network Service Chain Implementation.

We had couple of queries when we show cased it in ONS 2013 like guys from Midokura,Redhat etc are enquired about this blue print.

We would like to contribute this for Havana Release.

Regards,
Balaji.P
