This paper proposes a proactive optimal resource allocation scheme for elastic security Virtualized Network Functions (VNFs) in the Service Function Chaining on the Software Defined Network Function Virtualization (SDNFV-enabled) cloud environment. We firstly analyze our system model, and transform them into M/M/1/∞ and M/M/k queueing model. Then we define mathematical requirements by analyzing the new VNF resource allocation function and estimating the total number of packets in an SFCisystem. From these requirements, we finally propose a proactive resource allocation optimizer with solvable and practical constraints.
