【摘要】：統(tǒng)計(jì)數(shù)據(jù)顯示,P2P、在線視頻已經(jīng)徹底統(tǒng)治了當(dāng)今的互聯(lián)網(wǎng),互聯(lián)網(wǎng)80%的總流量都來自P2P和在線視頻應(yīng)用。這些應(yīng)用給客戶帶來豐富的互聯(lián)網(wǎng)體驗(yàn)的同時(shí),也給網(wǎng)絡(luò)的運(yùn)營者、管理者帶來了很大的挑戰(zhàn)。P2P和在線視頻應(yīng)用占用了運(yùn)營商城域網(wǎng)大量的帶寬資源,而其他一些業(yè)務(wù)的質(zhì)量無法保障,用戶抱怨增多,粘合度急劇下降,造成用戶流失。常熟廣電在發(fā)展寬帶業(yè)務(wù)的過程中也出現(xiàn)了類似的問題。有限的互聯(lián)網(wǎng)出口帶寬被大量在線視頻、P2P業(yè)務(wù)流量占據(jù),用戶體驗(yàn)變差,投訴量日益增長。本文首先提出了常熟廣電建設(shè)互聯(lián)網(wǎng)CDN(內(nèi)容分發(fā)網(wǎng)絡(luò))平臺(tái)的必要性,并對建設(shè)CDN平臺(tái)的幾個(gè)關(guān)鍵技術(shù)進(jìn)行了研究和闡述;然后對平臺(tái)的總體設(shè)計(jì)和各個(gè)子系統(tǒng)進(jìn)行研究和部署;最后對整個(gè)平臺(tái)的運(yùn)營情況進(jìn)行了測試和總結(jié)。實(shí)踐證明,互聯(lián)網(wǎng)CDN平臺(tái)的部署,對于解決常熟廣電互聯(lián)網(wǎng)出口帶寬不足的現(xiàn)狀,加速用戶體驗(yàn),具有積極的意義。
[Abstract]:Statistics show that online video has completely dominated the Internet today. The total traffic of Internet 80% comes from P2P and online video applications. These applications bring customers a rich Internet experience, but also give network operators. The manager has brought great challenges. P2P and online video applications have taken up a lot of bandwidth resources in the operator's metropolitan area network, while the quality of some other services is not guaranteed, user complaints have increased, and the degree of adhesion has plummeted. A similar problem has arisen in the development of broadband services in Changshu Radio and Television. The limited bandwidth of Internet exports is occupied by a large number of online video and P2P traffic, and the user experience becomes worse. The number of complaints is increasing day by day. Firstly, this paper puts forward the necessity of building Internet CDN (content distribution network) platform in Changshu Radio and Television, and studies and expounds several key technologies of building CDN platform. Then the overall design of the platform and the various subsystems are studied and deployed. Finally, the operation of the platform is tested and summarized. Practice shows that the deployment of the Internet CDN platform, It is of positive significance to solve the shortage of bandwidth of Changshu radio and television Internet export and accelerate the user experience.
