Abstract: A system and method for processing network packets based on NFV for ensuring high availability are disclosed. The disclosed system may include: at least one server, where a multiple number of VNF's for performing particular service functions are formed in the at least one server, each of the VNF's including at least one VNF instance; and a control apparatus that sequentially selects an M number of VNF's and selects one VNF instance from each of the selected M number of VNF's to configure an SFC, where the control apparatus may calculate an availability cost ratio value associated with each of the at least one VNF instance within VNF i+1 with respect to a VNF instance selected from VNF i (i being an integer from 1 to M) and may select a VNF instance within the VNF i+1 corresponding to the maximum value among the availability cost ratio values.
