This novel processing paradigm raises a number of issues from different points of view: the need for the availability of proper APIs and programming abstractions to allow the control plane to configure and instruct the data plane processing nodes; the data plane itself must be able to perform early-stage data elaboration at (or nearly at) the network line rate; the control plane must be able to cope with the possibly significant computation burden imposed by different use-cases—for example, a system for Deep Packet Inspection (DPI), or, even more complex, Security Information and Event Management (SIEM). 2.1.
