摘要： 工業(yè)互聯(lián)網(wǎng)現(xiàn)場(chǎng)存在大量異構(gòu)設(shè)備和網(wǎng)絡(luò)帶來(lái)的復(fù)雜性以及工業(yè)生產(chǎn)的實(shí)時(shí)性和可靠性問(wèn)題，如果數(shù)據(jù)分析和控制邏輯全部在云端實(shí)現(xiàn)，難以滿(mǎn)足工業(yè)場(chǎng)景的網(wǎng)絡(luò)需求，而通過(guò)邊緣計(jì)算在服務(wù)實(shí)時(shí)性和可靠性方面能夠滿(mǎn)足工業(yè)互聯(lián)網(wǎng)的發(fā)展需求。提出了面向工業(yè)互聯(lián)網(wǎng)的OLT融合邊緣計(jì)算三種技術(shù)方案，主要通過(guò)邊緣計(jì)算和OLT的業(yè)務(wù)連接、路由轉(zhuǎn)發(fā)以及管理功能等方面進(jìn)行了分析。對(duì)比了具有增值功能的OLT內(nèi)置型邊緣計(jì)算、具有通用功能的OLT內(nèi)置型邊緣計(jì)算以及OLT外置型邊緣計(jì)算三種方案的差異性，根據(jù)其差異性提出了適用于不同工廠(chǎng)的場(chǎng)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(chǎng)景中對(duì)邊緣計(jì)算的應(yīng)用需求越來(lái)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(chǎng)景對(duì)邊緣計(jì)算的需求。
