摘要: 边缘计算(edge computing, EC)是在靠近人、物或数据源头的网络边缘侧,融合网络、计算、存储、应用核心能力的新网络架构和开放平台.边缘计算将传统的集中式云计算处理的方式,改为将计算存储能力下移至网络边缘,面向用户和终端的方式,就近提供边缘智能服务.边缘计算极大地降低了由于数据回传造成的核心网和传输网的拥塞与负担,实现较低时延,带来较高带宽,同时能够快速响应用户请求并提升服务质量.当前,边缘计算已经成为未来第五代通信(5G)时代的重要使能技术,并写入第三代合作伙伴计划(3rd generation partnership project, 3GPP)标准.越来越多的运营商、设备商、芯片厂商加入建设边缘计算生态的行列,如何打造一个统一的标准化的边缘计算平台对于未来边缘生态的建设至关重要.因此,重点介绍当前边缘计算标准化的进展情况,从欧洲电信标准化协会(European Telecommunications Standards Institute, ETSI)最先提出边缘计算架构开始,到3GPP将边缘计算纳入未来5G发展的关键技术,再到中国通信标准化协会(China Communications Standards Association, CCSA)中边缘计算的立项与课题研究.每一部分的介绍均安排了大量对标准内容的分析和解释.最后介绍了近年来中国联通在边缘计算方面的研究成果.包括重要的边缘计算试点、联通未来边缘计算试点计划以及边缘计算的组网部署方案探索等内容.期望与产业界共同探讨边缘计算商业合作模式,共建网络边缘生态,全面推动5G业务的蓬勃发展.

Abstract: Edge computing is a new network architecture and open platform that integrates network, computing, storage, and application core capabilities on the edge of the network. Edge computing changes the way of traditional centralized cloud computing which moves computing and storage capabilities to the edge of the network. Edge computing can greatly reduce the congestion and burden of core network and transmission network, due to canceling the data backhaul. And it can lower the delay, bring high bandwidth. Also at the same time it can quickly respond to users’ requests and improve service quality. Now, edge computing has become an important enabling technology for the future 5G, and it has been written into 3GPP standard. More and more operators, equipment vendors and chip manufacturers join to construct the edge computing ecological. How to build a unified standardized edge computing platform for future ecological construction is very important. Therefore, this paper focuses on the progress of standardization of the current edge computing. From edge computing architecture was first proposed by ETSI, to edge computing has been listed as the key technology for future 5G development in 3GPP. The approval of projects of the edge computing in CCSA is also included. The introduction of each part has a great deal of analysis and explanation of the standard content. In the end, this paper introduces China Unicom’s edge computing research achievement in recent years, including the important edge computing experimental project, the pilot scheme for future edge computing of China Unicom and the exploration of the network deployment plan of edge computing. We are looking forward to discussing the edge computing commercial cooperation mode with all sectors so as to jointly build the network edge ecology and comprehensively accelerate the vigorous development of 5G services.
