【摘要】：校园网是学校重要的基础设施之一，，是学校多媒体教学平台、数字化管理、课程共享、数字教育资源库、思想文化教育等工作的基础平台，在促进思想文化交流且推动教育改革发展、丰富校园精神生活等方面起到了重要且积极作用。本文提出一个采用无源光网络（PON）技术为校园骨干传输网络，以高速率无线局域网（WLAN）技术作为终端接入手段为主要、有线接入为补充的，同时能支持多元化终端移动接入的新型校园网络构架规划设计。在所采取的方案中，PON技术具有高速带宽接入、支持并能满足现在和未来全业务接入需要、节省光纤纤芯资源、可大大提高光纤资源的利用率、运维简便、节能环保、支持QoS全业务保障等优点；WLAN则以安装便捷、使用灵活、易于扩展等优点作为PON技术的补充与拓展。本文的主要设计内容包括网络架构设计、ODN传输网络光纤覆盖设计、WLAN接入网覆盖设计三个方面。校园网络架构设计是校园网络规划设计的基础工作，而PON传输网络中ODN部分占据主要的资金预算投入，本文对ODN光缆覆盖规划设计以及、ODN网络光功率预算两个问题进行了深入研究。为了实现WLAN接入网络覆盖，本文给出了覆盖方式分析、容量规划设计、AP设备选择等结果。
[Abstract]:Campus network is one of the important infrastructure of school, it is the basic platform of multimedia teaching platform, digital management, curriculum sharing, digital education resource bank, ideological and cultural education, etc. It plays an important and positive role in promoting ideological and cultural exchange, promoting educational reform and development, enriching campus spiritual life and so on. This paper presents a campus backbone transmission network based on PON technology, with high rate wireless LAN (WLAN) technology as the main means of terminal access and cable access as a supplement. At the same time, the planning and design of a new campus network architecture can support mobile access of multiple terminals. In the scheme adopted, the technology of PON has high speed bandwidth access, supports and meets the needs of current and future full service access, saves fiber core resources, can greatly improve the utilization ratio of optical fiber resources, is simple in operation and maintenance, and can save energy and environmental protection. The advantages of supporting the full service guarantee of QoS are convenient installation, flexible use, easy extension and so on as the supplement and extension of PON technology. The main design content of this paper includes three aspects: network architecture design, optical fiber coverage design of ODN transmission network and WLAN access network coverage design. The campus network architecture design is the basic work of the campus network planning and design, while the ODN part of the PON transmission network accounts for the main investment in the capital budget. In this paper, the design of optical cable coverage and the optical power budget of ODN network are studied. In order to realize WLAN access network coverage, this paper gives the results of coverage mode analysis, capacity planning design and AP equipment selection.
