VFP: A Virtual Switch Platform for Host SDN in the Public Cloud

The Virtual Filtering Platform (VFP) is a cloud-scale programmable virtual switch providing scalable SDN policy to one of the world's largest clouds, Microsoft Azure. It was designed from the ground up to handle the programmability needs of Azure's many SDN applications, the scalability needs of deployments of millions of servers, and to deliver the fastest virtual networks in the public cloud to Azure's VMs through hardware offloads.
