摘要:

边缘计算和共识是分布式计算领域的2个重要研究课题。边缘计算将一部分资源下放到靠近终端设备的边缘侧以提高计算效率和质量,共识通过实现分布式个体状态的一致性为分布式系统提供安全保障。在简要综述相关文献的基础上,总结和分析了边缘计算与共识的互惠关系:边缘计算架构为共识算法研究提供了理论模型的创新,共识为边缘计算提供了理想的系统安全性。将边缘计算和共识算法有机地进行结合,提出“共识边缘计算”的概念,在能源互联网的背景下对这种结合的应用进行展望性分析,并进一步列举可能的发展方向。

Abstract:

Edge computing and consensus are two important research topics in the field of distributed computing. Edge computing delegates some resources to the edge near terminal devices to improve the efficiency and quality of computing, while consensus provides security for distributed systems by achieving the consistency among the states of distributed individuals. After a brief review of related literature, this paper summarizes and analyzes the reciprocity between edge computing and consensus: the edge computing architecture provides innovation for the theoretical model of consensus study, and consensus provides desirable security for edge computing systems. In this paper, edge computing and consensus algorithm are combined organically, and the concept of "consensus edge computing" is established. The application of this combination is prospectively analyzed under the background of energy internet, and then possible development directions are enumerated.

Key words: edge computing, consensus, energy internet, internet of things, distributed algorithms, blockchain
