Open Stack

Doesn't the current service framework address the support of VM based services ? 
The current limitations to HA-Proxy seems to be due to SW development resources instead of the proposed framework limitations which should support any types of services, i.e. hardware-based or SW-based including VM ?

Thanks
Christian

Yes, I agree that this blue-print is to focus on VM form-factor and NFV deployment using Quantum.

We tried to bring in more modular and flexible approach so that tenants can have more options for choosing the vendor and their NFV appliances. And as well multiple vendors can use the same network service infrastructure create their own plug-ins for deploying their NFV appliances.

Any comments on improving this further are most welcome.

I agree with Sumit, but I would say that NFV focuses specifically on virtualizing network services, so I would expect this blueprint to focus on the virtual form factor. Seeing how this fits into the broader service insertion story will be a good first step.

Thanks,
Kyle

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.
