摘要： 隨著通信技術(shù)的發(fā)展和智慧園區(qū)類需求的不斷增加，傳統(tǒng)園區(qū)網(wǎng)絡(luò)也面臨著帶寬不足、組網(wǎng)僵化、物聯(lián)網(wǎng)接入困難等重大挑戰(zhàn)。產(chǎn)業(yè)界內(nèi)近幾年通過在園區(qū)網(wǎng)絡(luò)引入PON、WDM等網(wǎng)絡(luò)技術(shù)，或改進(jìn)優(yōu)化現(xiàn)有以太網(wǎng)技術(shù)，以應(yīng)對面臨的問題和挑戰(zhàn)。通過綜述產(chǎn)業(yè)界代表性組網(wǎng)方案，分析技術(shù)原理、特點和組網(wǎng)優(yōu)劣勢，以園區(qū)網(wǎng)場景為索引分別進(jìn)行適應(yīng)性判別和總結(jié)，以達(dá)到技術(shù)先進(jìn)性的對比和判斷。通過對比可以更為深入理解現(xiàn)有技術(shù)的不足和新型技術(shù)的優(yōu)劣勢，以期在未來組網(wǎng)建設(shè)時作為方案選型參考。

Abstract： With the development of communication technology and the increasing demand for smart campuses, traditional campus networks are also faced with major challenges such as insufficient bandwidth, inflexible networking, and difficulty in accessing the Internet of Things. In recent years, the industry has introduced network technologies such as PON and WDM in the campus network, or improved and optimized the existing Ethernet technology to deal with the problems and challenges. This paper summarizes the representative networking solutions in the industry, analyzes the technical principles, characteristics, and networking technology advantages and disadvantages, and uses the campus network scene as standard to judge and summarize the adaptability respectively, so as to achieve the comparison and judgment of technological advancement. Through the comparison, the shortcomings of the existing technology and the advantages and disadvantages of the new technology can be more deeply understood, in order to be used as a reference for solution selection in the future network construction.

園區(qū)網(wǎng)絡(luò)相對于廣域網(wǎng)是承載企業(yè)內(nèi)部數(shù)據(jù)通信的網(wǎng)絡(luò)，從校園到工業(yè)園區(qū)，再到酒店房間、醫(yī)療診室，都屬于園區(qū)網(wǎng)絡(luò)范疇。
隨著通信技術(shù)的發(fā)展和智慧園區(qū)類需求的不斷增加，傳統(tǒng)園區(qū)網(wǎng)絡(luò)也面臨著重大挑戰(zhàn)，主要體現(xiàn)在：帶寬升級難、難以擴展、繼承性差；多網(wǎng)并存、管理復(fù)雜；物聯(lián)網(wǎng)化；園區(qū)傳輸覆蓋范圍有限；成本和功耗較高等。面對以上種種挑戰(zhàn)，多種基于光通信技術(shù)的園區(qū)網(wǎng)方案爭相推出。本文主要目的即是分析相關(guān)通信技術(shù)和方案，給出各個技術(shù)和方案的適用場景對比分析。
