                        draft-barkai-lisp-nfv-13

Abstract

   This draft describes an RFC 6830 Locator ID Separation Protocol
   (LISP) based distributed flow-mapping-fabric for dynamic scaling of
   virtualized network functions (NFV).  Network functions such as
   subscriber-management, content-optimization, security and quality of
   service, are typically delivered using proprietary hardware
   appliances embedded into the network as turn-key service-nodes or
   service-blades within routers.  Next generation network functions are
   being implemented as pure software instances running on standard
   servers - unbundled virtualized components of capacity and
   functionality.  LISP-SDN based flow-mapping, dynamically assembles
   these components to whole solutions by steering the right traffic in
   the right sequence to the right virtual function instance.
