Overview

The Azure Virtual Filtering Platform (VFP) is Azure’s software defined networking vswitch, enabling us to provide core SDN functionality for Azure networking services. VFP is a programmable switch that exposes an easy-to-program abstract interface to network agents that act on behalf of network controllers like our virtual networks controller and our software load balancer controller. By leveraging host components and doing much of packet processing on each host running in the datacenter, the Azure SDN data plane scales massively – both out and up nodes from 1 Gbs to 50 Gbs, and growing.
