Video web site Transformation Peer-to-peer Rife

Communications Industry newspaper reporter Shuje

"The world is changing so fast that August and now are two worlds." "Tudou CEO Wang is undoubtedly a real reflection of the drastic changes in the recent economic environment." High financing, large burning of money, access to traffic, overseas listing was once a video-sharing site success Road map of the choice, but in crazy burning money and access to huge user traffic, video sites have to face the capital and advertising market double winter.

There is no doubt that the Internet is the first to be affected by the profit model is not clear, the cost of high video sites.

　The transformation of the Peer-to-peer in the storm

This month, Tudou officially announced that its Peer-to-peer video accelerator, "Fast potatoes," has more than 1 million people online daily, with more active users than 10 million. According to Wang, Tudou has regained the Peer-to-peer software "fast potatoes", which it started two years ago, in the hope of cutting bandwidth costs from technology.

Video sites have been the biggest cost is bandwidth.

Prior to the industry has counted a ledger: At present Youku's daily video playback volume over 160 million, the monthly bandwidth cost about 10 million yuan, the annual bandwidth consumption of more than 120 million yuan. Prior to the "Communications industry newspaper" reporter during the Olympic Games, cool 6 in order to ensure the live broadcast during the Olympic Games, the site added thousands of servers, and the bandwidth adjusted to 220G, only in the bandwidth of an investment, will be more than Peer-to-peer type of Web site input more than millions of yuan.

Up to now, whether it is from the UGC content uploaded by users, or with the content provider to cooperate with some of the high-definition film and television content, Youku is still used by the traditional p2s technology. Youku CEO Koo in the "Communications industry newspaper" reporter interviewed, said that the traditional Peer-to-peer technology general requirements is "hot content", and Youku and other video sites due to the large number of video, even if the use of Peer-to-peer methods can not play a cost-saving effect.

But for the sake of saving operation cost, Peer-to-peer VOD has become a common choice of many video websites. Not only is Tudou's "fast potatoes", 酷6网 's "fast cool 6", even Youku itself has developed a "I cool" peer-to-peer software, users can use this software on demand and download Youku site all video. According to the popular CEO Lo Jiangchun, the use of Peer-to-peer technology to occupy the popularity of the equivalent of similar video sharing site about 1/10.

Single on the amount of investment, venture capital seems to be more important to video-sharing sites, but in fact, Peer-to-peer streaming media site may be more moist days, most of which have achieved a single monthly profit.

　　Operator scratching head

"The increase in peer-to-peer traffic is not a good news for operators," he said. An industry insider told reporters. Because of the out-of-order and free use of peer-to-peer traffic, operators are unable to gain the investment return of bandwidth construction, and also reduce the network quality of fee-based service.

According to the statistics of China Telecom, Peer-to-peer Service has become the main use of bandwidth consumption backbone network. The general shift in video sites will obviously exacerbate this situation. It is understood that the bandwidth of a high-definition video is equivalent to 35,000 times times the consumption of web pages.

In the video site transformation process, there will be operators have to face the dilemma. One side is that the video site improves the user experience while reducing costs, while the other side is that operators, while reducing revenue, still have to cope with greater network traffic accompanying high-definition video. The current Internet capacity will be depleted within two years unless Internet backbone operators invest 137 billion of billions of dollars to build new infrastructure, according to a report released recently by a US research firm.

"The biggest stress is the backbone. "In response to the growing network blockage, an industry expert believes that, because in recent years the operator has been in the metropolitan area network bandwidth expansion, so the city area network silting up the problem is relatively easy, but the backbone of the network to withstand the most pressure." "If the network blockage situation intensifies, do not rule out operators will take the flow of fees, limit the length of download and so on." "One industry analyst thinks.

　　Amnesty Peer-to-peer

However, Peer-to-peer as a popular technology, operators only limit the problem is difficult to solve. "Lo Jiangchun said. According to the survey, Peer-to-peer applications have become the main choice for subscribers to the broadband subscription, he said.

According to statistical data, as of January 2008, Internet Broadband access users close to 67 million households. But that figure is still less than 1/3 of Chinese netizens. "The total number of netizens, especially the monthly broadband subscribers, still has a lot of room for growth." "Lo Jiangchun said. More importantly, each broadband subscribers more than 100 yuan per month for the Apru value of the declining operators, the temptation is big.

It is precisely because of the huge benefits, how to put the Peer-to-peer into the controllable range has become the operator's first problem, because of this, become a new point of interest. Unlike Peer-to-peer random selection of resource points, a manageable peer-to-peer can use network topology data to select the best peer to improve network routing efficiency.

According to Lo Jiangchun's introduction, manageable Peer-to-peer has turned the loose peer-to-peer approach into a planned deployment and application. Therefore, in the premise of improving customer satisfaction, it further reduces the peer-to-peer traffic to other operators or out of the province, so the pressure on the network of operators is greatly reduced, so it is welcomed by operators.

In this respect, Lo Jiangchun explained that the popular use of a very advanced management Peer-to-peer technology, can be the same area of traffic control within the local operator's network.

Dongzhenjiang, director of the Department of Intelligent Network Systems at ZTE Network Division, said the current problem with Peer-to-peer would also be a problem that mobile internet might face.
