【摘要】：随着三网融合的概念的提出，电信网络和广播电视网络的互联互通的需求与日俱增。鉴于电信网络的现实中的各种优势，广播电视网络在三网融合的竞争中必须做到扬长避短，充分利用自己的现有网络的资源进行技术改造。本文的研究重点在于，根据我国广播电视网络的实际情况，基于同轴电缆双向接入改造技术（HINOC）来进行实现和测试，具体如下：本文首先阐述了接入网的概念，继而简单介绍了有线接入网的几种技术标准并对比了它们性能的优劣及各自的应用场景。随着有线电视新的应用场景的出现，原有的有线接入网技术无法满足有线电视对有线接入双向改造的技术需求。欧美发达国家广电网络运营商和设备上不断地推出了各种新技术来对广电网络进行改造，以满足互联网时代用户对双向交互式多媒体应用日益剧增的需求。由此，“EoC”技术应运而生。“EoC”技术利用广电网络庞大的到户的同轴电缆资源，将高速光纤骨干网络和同轴电缆资源进行无缝对接，实现了利用同轴电缆进行高速宽带接入。然而，各种“Eoc”技术的层出不穷也导致设备之间的互联互通和性能匹配成为了广电网络发展的阻碍。然后我们介绍了全球范围内主流的“Eoc”技术，对比了它们的技术性能并分析了它们的应用场景。为了避免出现其他国家在网络改造时遇到的问题，，我国设计了具有自主知识产权的HINOC技术，该技术充分吸收了国外的先进经验，同时也结合我国网络资源的实际情况。本文在HINOC1.0协议标准的基础上，结合自己的实际实验条件，利用FPGA实现HINOC终端协议功能。本文主要侧重在PHY层和MAC层协议的FPGA实现，部分成熟的FPGA设计利用了IP CORE来实现。本文最后对HINOC1.0协议的FPGA进行了测试并分析。
[Abstract]:With the introduction of the concept of three-network convergence, the demand for interconnection between telecommunication network and radio and television network is increasing day by day. In view of the various advantages of the telecommunication network in reality, the radio and television networks must make full use of their existing network resources to carry out technical transformation in the competition of the integration of the three networks. The research focus of this paper is that according to the actual situation of radio and television network in China, based on the coaxial cable two-way access technology HINOC) to carry out the implementation and testing, the details are as follows: firstly, this paper describes the concept of access network, Then several technical standards of wired access network are introduced and their performance and application scenarios are compared. With the emergence of new application scenarios of CATV, the original CATV access network technology can not meet the needs of CATV two-way transformation of cable access. In the developed countries of Europe and the United States, the operators and equipments of the radio and television network have continuously introduced various new technologies to transform the radio and television networks, in order to meet the ever-increasing demand of users for two-way interactive multimedia applications in the era of the Internet. As a result, "EoC" technology emerged as the times require. "EoC" technology makes use of the huge coaxial cable resources of the radio and television network to seamlessly connect the high-speed optical fiber backbone network with the coaxial cable resources. The use of coaxial cable for high speed broadband access is realized. However, the emergence of various "EOC" technologies also leads to interconnection and performance matching between devices, which is a hindrance to the development of radio and television networks. Then we introduce the global mainstream EOC technology, compare their technical performance and analyze their application scenarios. In order to avoid the problems encountered by other countries in network transformation, HINOC technology with independent intellectual property rights has been designed in China, which fully absorbs the advanced experience of foreign countries and combines the actual situation of network resources in our country at the same time. Based on the HINOC 1.0 protocol standard and the actual experimental conditions, this paper uses FPGA to realize the HINOC terminal protocol function. This paper focuses on the implementation of PHY layer and MAC layer protocol based on FPGA. Some mature FPGA design uses IP core to implement. Finally, the FPGA of HINOC 1.0 protocol is tested and analyzed.
