A Hot Redundancy Method For Virtualized Industrial Edge Applications

With the rapid evolution of industrial architecture, industrial edge computing is one of the most popular architectures at present. However, backup methods designed for traditional industrial architectures are not satisfactory in terms of device cost and applicability when they are applied in this new architecture. Against this background, this work presents a new backup method for industrial edge applications with better performance on resource consumption and high stability. The Function Block of IEC 61499 is used as the standard industrial edge application in this work. By carrying out experiments and employing multiple backup approaches, the resource occupancy rate and recovery time can be reduced simultaneously. The innovative methods and resource allocation models tackle the limitation of traditional backup methods effectively.
