【摘要】:隨著三網(wǎng)融合的概念的提出,電信網(wǎng)絡(luò)和廣播電視網(wǎng)絡(luò)的互聯(lián)互通的需求與日俱增。鑒于電信網(wǎng)絡(luò)的現(xiàn)實中的各種優(yōu)勢,廣播電視網(wǎng)絡(luò)在三網(wǎng)融合的競爭中必須做到揚長避短,充分利用自己的現(xiàn)有網(wǎng)絡(luò)的資源進行技術(shù)改造。 本文的研究重點在于,根據(jù)我國廣播電視網(wǎng)絡(luò)的實際情況,基于同軸電纜雙向接入改造技術(shù)(HINOC)來進行實現(xiàn)和測試,具體如下: 本文首先闡述了接入網(wǎng)的概念,繼而簡單介紹了有線接入網(wǎng)的幾種技術(shù)標(biāo)準(zhǔn)并對比了它們性能的優(yōu)劣及各自的應(yīng)用場景。隨著有線電視新的應(yīng)用場景的出現(xiàn),原有的有線接入網(wǎng)技術(shù)無法滿足有線電視對有線接入雙向改造的技術(shù)需求。歐美發(fā)達國家廣電網(wǎng)絡(luò)運營商和設(shè)備上不斷地推出了各種新技術(shù)來對廣電網(wǎng)絡(luò)進行改造,以滿足互聯(lián)網(wǎng)時代用戶對雙向交互式多媒體應(yīng)用日益劇增的需求。由此,“EoC”技術(shù)應(yīng)運而生。“EoC”技術(shù)利用廣電網(wǎng)絡(luò)龐大的到戶的同軸電纜資源,將高速光纖骨干網(wǎng)絡(luò)和同軸電纜資源進行無縫對接,實現(xiàn)了利用同軸電纜進行高速寬帶接入。然而,各種“Eoc”技術(shù)的層出不窮也導(dǎo)致設(shè)備之間的互聯(lián)互通和性能匹配成為了廣電網(wǎng)絡(luò)發(fā)展的阻礙。然后我們介紹了全球范圍內(nèi)主流的“Eoc”技術(shù),對比了它們的技術(shù)性能并分析了它們的應(yīng)用場景。為了避免出現(xiàn)其他國家在網(wǎng)絡(luò)改造時遇到的問題,,我國設(shè)計了具有自主知識產(chǎn)權(quán)的HINOC技術(shù),該技術(shù)充分吸收了國外的先進經(jīng)驗,同時也結(jié)合我國網(wǎng)絡(luò)資源的實際情況。 本文在HINOC1.0協(xié)議標(biāo)準(zhǔn)的基礎(chǔ)上,結(jié)合自己的實際實驗條件,利用FPGA實現(xiàn)HINOC終端協(xié)議功能。本文主要側(cè)重在PHY層和MAC層協(xié)議的FPGA實現(xiàn),部分成熟的FPGA設(shè)計利用了IP CORE來實現(xiàn)。本文最后對HINOC1.0協(xié)議的FPGA進行了測試并分析。
[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.
