Description
Overlay Network Engine (ONE) is a VPP project that enables programmable dynamic Software Defined overlays. ONE uses an extended LISP-based map-assisted control plane to dynamically lookup overlay-to-underlay address mappings, as well as forwarding policies, on demand and as packets arrive. This includes policies such as connectivity, encryption, traffic engineering and virtual topologies, access control, and service chaining. The looked up mappings and forwarding policies are cached locally for a TTL period until they time out. The mapping and forwarding policy information is then used to encapsulate overlay packets towards their associated destinations or next hops.
ONE can use and operate a variety of encapsulation formats for the overlay including GRE, VXLAN-GPE (Generic Protocol Extension) [1], which is effectively merging VXLAN and LISP [2] encapsulations in a single format that supports multi-protocol payloads, etc. The control plane can be used to fetch the encapsulation capabilities of a destination as part of its mapping and forwarding policies.
An external open SDN controller will be used as the mapping system to store and provide the mapping and forwarding policies.
