This deliverable presents the analysis, design and prototype implementation of SELFNET mechanisms and procedures for the encapsulation of Network Function Virtualization (NFV) and Software Defined Network (SDN) applications. These applications are SELFNET sensors and actuators that will support the four use cases defined in the project: self-optimization, self-healing, self-protection and a composed use case combining the previous three. Their encapsulation basically provides common and uniform primitives and procedures to manage their lifecycle (instantiation, configuration, termination, etc.) irrespectively of the specific application logic. In particular, two prototypes are released with this deliverable in support of Virtual Network Functions (VNFs) and SDN application lifecycle management.
