"Will hardware offload help Open vSwitch to scale above 10G, and keep the CPU cool?

Our journey starts with why hardware offload is needed for Open vSwitch? Can we scale consuming more and more CPU resources for handling networking traffic?

What can hardware bring to the table to help us free these CPU resources for the real task at hand, i.e. running containers and/or virtual machines?

If the hardware can help, how will this all be utilized in a vendor natural way? TC Flower to the rescue...

But what is TC Flower, how does it work, and finally how does it integrate with Open vSwitch.

And for the conclusion... How well will Open vSwitch with TC Flower perform? We will present the results based on our tests using the Physical to Virtual to Physical (PVP) test methodology."
