摘要
近年来，骨干网的能力进一步增强，与此同时接入网方面却没有大的改进。接入网的能力的增长远远落后于Internet 流量的快速增长，因而接入网成为高效的LAN 和骨干网发展的瓶颈，又被称为“最后一公里”。EPON由于集中了以太网设备价格低廉和光纤能够提供高带宽的优点，成为下一代接入网的最佳选择。 本论文首先从接入网的基本概念出发，对接入网的定义与定界和拓扑结构进行介绍，然后介绍了目前流行的几种宽带接入技术，引出EPON 接入技术，并对洁银
EPON 技术的产生背景、网络结构、工作原理和技术特点作进一步介绍；进而从EPON 业务接入出发，分析EPON 系统支持的业务类型以及需求，设计了一套支持多业务的接入解决方案； 最后从EPON 的应用角度，阐述EPON 接入网的组网原则，运用EPON技术对滑县英民小区进行接入组网。 关键词：接入网，EPON，多业务。
ABSTRACT
br710
In recent years, the capability of Backbone Network has been more increased, the acces
s network has not much improvement in the mean time. The rate of increase of capability of the access network is far behind the flow of Internet, so the access network has become the bottleneck of the development of the high efficiency LAN and Backbone Network, and it goes the name of “the last one kilometer”. Due to EPON is a technology with the advantages of the low-price Ethernet equipments and fiber which can provide high bandwidth, it becomes the best choice of the next access network. .
The article proceed from the basic concept of access network, introduces the definition and demarcation/opological structure of access network, then introduces some Broadband access techenologies that are popular now, to draw the access technology of EPON, and futher introduces the background of generation/ network structure/theory of operation/technique feature of EPON; And proceed from the service access of EPON, analyze the service types and demands which EPON system supports, design a access scheme which can support different services; finally, from the application angle of EPON, expatiate the meshing principle, and aim at different kinds of users, separate select campus network/commercial client/denizen user these representative user, base on EPO
N and use access technologies with yingmin uptown.
Key words: :Access Network, EPON，Different Services
