Network Overlays are established as major enablers for Network virtualization. The growing prevalence of overlays, partially due to the broad and accelerated adoption of SDN and NFV, has raised the need for improved programmability to simplify provisioning, change propagation, and policy application by network admins, as well as network application developers. The Fast Data project (FD.io) has recently joined Linux Foundation, as a new open source project aiming at providing an I/O services framework for the next wave of high-performance network and storage. At the heart of FD.io is the Vector Packet Processor (VPP), a DPDK enabled forwarding engine. In this talk, we will give an overview of the current overlay capabilities in VPP, with a focus on LISP/VXLAN-GPE, and discuss how FD.io together with OpenDaylight SDN Controller platform can be used to improve programmability in overlays.
