基于边缘计算的物端系统挑战与愿景
|
摘要
针对物端计算系统面临的"昆虫纲悖论"和"数据过于集中"2大生态问题,从计算系统的角度,讨论分析了其在系统架构、应用层协议、资源管理、开发与运行时、计算负载调度5个方面面临的挑战。提出了物端控域计算机设计愿景,即将物端计算系统划分为具有相同或兼容管理策略的控域,并将每个域看作一台分布式计算机,为其设计物端信息总线架构原型。
To address the two ecosystem problems of things system:"Paradox of Classis Insecta"and"Centralized Data", five challenges of things system in perspective of computing system are discussed in this paper. These challenges include system architecture, application protocol, resource management, application development and runtime environment, and computing payload scheduling. Then, the design vision of the physical-zone-of-control computer is put forward, which divides things system into multiple zones of control with same or compatible management policy. The physical information bus architecture prototype which regards every zone as the distributed computer is finally proposed.
