【摘要】：隨著互聯(lián)網(wǎng)技術(shù)的提高和寬帶用戶的普及,固網(wǎng)運(yùn)營(yíng)商提供的寬帶業(yè)務(wù)已經(jīng)發(fā)展到基本飽和狀態(tài)。面對(duì)這種市場(chǎng)現(xiàn)狀,必須發(fā)現(xiàn)和創(chuàng)造更多商業(yè)機(jī)會(huì),尋找新的業(yè)務(wù)增長(zhǎng)點(diǎn)來(lái)提升差異化競(jìng)爭(zhēng),突破終端瓶頸,培養(yǎng)已有用戶的忠誠(chéng)度,降低客戶流失率。這時(shí)IPTV業(yè)務(wù)應(yīng)運(yùn)而生,充分有效的利用現(xiàn)有網(wǎng)絡(luò)資源,擴(kuò)展了互聯(lián)網(wǎng)業(yè)務(wù)的使用終端,更好的適應(yīng)當(dāng)今網(wǎng)絡(luò)飛速發(fā)展的趨勢(shì),提升了固網(wǎng)運(yùn)營(yíng)商的核心競(jìng)爭(zhēng)力。IPTV利用已有寬帶網(wǎng)絡(luò)的基礎(chǔ)設(shè)施優(yōu)勢(shì),依托其海量高清的試聽(tīng)內(nèi)容儲(chǔ)備和互聯(lián)網(wǎng)雙向交互的技術(shù)優(yōu)勢(shì),為用戶提供了更個(gè)性化更多選擇的新一代電視收視方式,無(wú)論在在內(nèi)容和形式等方面都超過(guò)傳統(tǒng)電視,使用戶得到更靈活更體貼的服務(wù)。PTV也為電信運(yùn)營(yíng)商啟動(dòng)了潛在的新業(yè)務(wù)新收入的機(jī)遇,業(yè)務(wù)融合是網(wǎng)絡(luò)發(fā)展的趨勢(shì),IPTV業(yè)務(wù)的開(kāi)展是促使三網(wǎng)融合的契機(jī),前景非常樂(lè)觀。2012年起,B市聯(lián)通開(kāi)始投入IPTV業(yè)務(wù)的建設(shè)與試點(diǎn),作者參與了該市聯(lián)通IPTV業(yè)務(wù)的基于IP城域網(wǎng)的網(wǎng)絡(luò)現(xiàn)狀,本課題首先對(duì)整體架構(gòu)和網(wǎng)絡(luò)容量是否能夠滿足IPTV業(yè)務(wù)的開(kāi)通做了評(píng)估和預(yù)測(cè),根據(jù)IPTV的業(yè)務(wù)特性,在網(wǎng)絡(luò)端采取組播技術(shù)作為首要關(guān)鍵支撐技術(shù)來(lái)節(jié)省帶寬,解決視頻流的復(fù)制問(wèn)題。而后給出了IPTV業(yè)務(wù)承載方案,包括IPTV端到組網(wǎng)方案、STB(Set Top Box,網(wǎng)絡(luò)機(jī)頂盒)的網(wǎng)絡(luò)接入認(rèn)證和地址分配方案、組播復(fù)制點(diǎn)選擇方案等。詳細(xì)闡述了實(shí)現(xiàn)IPTV業(yè)務(wù)涉及到的幾種IP組播協(xié)議,制定了IPTV業(yè)務(wù)組播部署方案。最后通過(guò)測(cè)試實(shí)際驗(yàn)證了方案可以實(shí)現(xiàn)預(yù)期效果,在幾個(gè)試點(diǎn)小區(qū)實(shí)現(xiàn)了IPTV業(yè)務(wù)。目前,該IPTV試點(diǎn)項(xiàng)目已經(jīng)在B市正常投入使用,網(wǎng)絡(luò)運(yùn)行正常,達(dá)到了該項(xiàng)目的預(yù)期設(shè)計(jì)要求。在文章的最后,對(duì)該方案進(jìn)行了總結(jié),并從IPTV長(zhǎng)期規(guī)�；陌l(fā)展考慮,提出了B市聯(lián)通城域網(wǎng)的不足,對(duì)下一步的網(wǎng)絡(luò)優(yōu)化和改造工作進(jìn)行了展望。
[Abstract]:With the improvement of Internet technology and the popularity of broadband users, broadband services provided by fixed network operators have developed to a basic saturation state. In the face of this market situation, we must find and create more business opportunities, find new business growth points to enhance differentiated competition, break through terminal bottlenecks, cultivate the loyalty of existing users, and reduce customer turnover. At this time, the IPTV service emerged as the times require, making full and effective use of existing network resources, expanding the terminal of Internet services, and better adapting to the rapid development trend of today's network. Improve the core competitiveness of fixed network operators. IPTV takes advantage of the existing broadband network infrastructure, relying on its massive high-definition audition content storage and two-way Internet interaction technology advantage, Provides users with a more personalized and more selective new generation of TV viewing, both in terms of content and form than traditional television, Making users get more flexible and considerate service. PTV also starts the potential new business revenue opportunities for telecom operators. Service convergence is the trend of network development and IPTV service development is an opportunity to promote the integration of three networks. The prospects are very optimistic. Since 2012, China Unicom has begun to invest in the construction and pilot of IPTV services, and the author has participated in the current situation of IP man based network of IPTV services in the city Unicom. In this paper, we first evaluate and predict whether the whole architecture and network capacity can meet the requirements of IPTV services. According to the characteristics of IPTV services, multicast technology is adopted as the first key supporting technology to save bandwidth at the network end. Solve the problem of video stream replication. Then, the scheme of IPTV service carrying is presented, including the network access authentication and address assignment scheme of IPTV end-to-network scheme (STB-STB (Set Top Box, network set-top box), the scheme of multicast replication point selection and so on. Several IP multicast protocols involved in implementing IPTV services are described in detail, and a multicast deployment scheme for IPTV services is developed. Finally, the test results show that the scheme can achieve the desired results, and the IPTV service is implemented in several pilot communities. At present, the IPTV pilot project has been put into use in B city, and the network is running normally, which meets the expected design requirements of the project. At the end of the paper, the scheme is summarized, and considering the long-term development of IPTV, the shortcomings of the metropolitan area network of Unicom in B city are put forward, and the future work of network optimization and transformation is prospected.
