摘要： 工业互联网现场存在大量异构设备和网络带来的复杂性以及工业生产的实时性和可靠性问题，如果数据分析和控制逻辑全部在云端实现，难以满足工业场景的网络需求，而通过边缘计算在服务实时性和可靠性方面能够满足工业互联网的发展需求。提出了面向工业互联网的OLT融合边缘计算三种技术方案，主要通过边缘计算和OLT的业务连接、路由转发以及管理功能等方面进行了分析。对比了具有增值功能的OLT内置型边缘计算、具有通用功能的OLT内置型边缘计算以及OLT外置型边缘计算三种方案的差异性，根据其差异性提出了适用于不同工厂的场景需求。

Abstract： The industrial internet site has the complexity brought by a large number of heterogeneous devices and networks, as well as the real-time and reliability problems of industrial production. If data analysis and control logic are all implemented in the cloud, it is difficult to meet the network requirements of industrial scenarios. However, edge computing can meet the development needs of the industrial internet in terms of service real-time and reliability. This paper proposes three technical solutions for optical line terminal(OLT) converged edge computing for industrial internet,mainly through the edge computing and OLT business connection, route forwarding and management functions and other aspects of the analysis. Comparing the differences among the three solutions of OLT built-in edge computing with value-added functions, OLT built-in edge computing with general functions, and OLT external edge computing, according to their differences, the scene requirements applicable to different factories are proposed.
Key words : edge computing；optical line termina；built-in resource board

隨著工業(yè)互聯(lián)網(wǎng)的快速發(fā)展，工業(yè)場景中對(duì)邊緣計(jì)算的應(yīng)用需求越來越多，其中包括數(shù)據(jù)預(yù)處理、低時(shí)延、多接入以及安全和隱私等。這也導(dǎo)致數(shù)據(jù)傳送量不斷增加，海量終端接入及數(shù)據(jù)傳輸、處理、存儲(chǔ)的需求極大地增加了網(wǎng)絡(luò)負(fù)荷，并對(duì)網(wǎng)絡(luò)帶寬提出了更高的需求。表1列舉了一些工業(yè)典型場景對(duì)邊緣計(jì)算的需求。
