We, the VFP team, describe here our goals and motivations in building VFP, VFP\u2019s design, and lessons we learned from production deployments. We also compare our design with that of other popular host SDN technologies such as OpenFlow and Open vSwitch (OVS) to show how our constraints in the public cloud can differ from those of popular open source projects. We believe these lessons can benefit the SDN community at large. <\/p>\n","protected":false},"excerpt":{"rendered":"

The Virtual Filtering Platform (VFP) is a cloud-scale programmable virtual switch providing scalable SDN policy to one of the world\u2019s largest clouds, Microsoft Azure.
