摘要
随着万物互联时代的到来,物联网设备数量呈爆炸式增长,在传统的云计算模型下,需要将终端设备产生的海量数据传输到云计算中心服务器,而海量数据传输所带来的时延无法满足当前多种实时性服务的时延要求。在此背景下,边缘计算的出现开创了能够在网络边缘处收集和处理数据的新型计算模式,为解决传统云计算模式中的时廷、带宽和负载等问题带来了极大便利。边缘计算通过将部分云中心的功能拓展到网络边缘,为终端设备提供有效的数据访问、计算、处理、存储、控制等服务,实现了从云到物之间无缝连接,被认为是实现万物互联的基础。
With the upcoming era of the Internet of Everything(IoE),the number of loE devices is growing explosively.Under the traditional cloud computing model,the massive data generated by the terminal equipment needs to be transmitted to the server of the cloud computing center,and the delay caused by the massive data transmission cannot meet the delay requirements of current multiple real-time services.In this context,the emerging edge computing creates a new computing mode that can collect and process data at the edge of the network,which brings great convenience to solve the problems of delay,bandwidth and load in the traditional cloud computing mode.By extending the functions of some cloud centers to the edge of the network,edge computing prov ides fective data access,computing,processing,storage,control and other services for terminal devices,and realizes the seamless conection between eloud and objects,which is considered as the basis for IoE.
