A Difference Detection Mechanism Between API Cache and Data Center in Smart Manufacturing

Abstract

According to the concept of edge computing, some service and data should be moved to the equipment to enhance the computation efficiency. For example, in the software-defined hybrid cloud (SDHC) [1], moving the setting of production lines from the data center to the application programming interface (API) servers decreases the time required to verify the access traffic. However, capturing the setting difference between API servers and the data center is a critical problem. In this paper, we propose the partition and pass (PnP) mechanism to synchronize the production line settings saved in the API servers with that in the data center. In the case study, we show that the approximation ration is 1 / 2 comparing with current solutions. In other words, applying PnP in the SDHC will increase the computation performance in saving manufacturing data.
