Global network capacity doubled growth rate slowed down two years


technology news (Liu Xuetong) September 7th Beijing time news, according to foreign media reports, according to Telegeography data show that the global network capacity spent two years has doubled, but the rate of growth is slowing.


from 2008 to 2012 the global broadband growth trend (Tencent technology plan)

according to the analysis of the company’s Telegeography in September 6th released information shows that in order to fully saturated the current network capacity, the need for 77Tbps (megabytes per second) content. Although the 77Tbps network capacity will seem shocking, but now the overall network capacity growth is slowing. This is because the new access network users are gradually reduced, while the use of network content is constantly improving.

Telegeography claims that, although there are 19 million people in the United States is not connected to broadband, but due to various reasons, the number of new broadband users gradually reduced. This means that the Internet service providers will save a lot of money, and the cost of network investment will be reduced.

this means that the global network capacity will be in 2011 to years in the past two years, an increase of 40%. Just as Internet vendors complain that the existing broadband network is not able to meet the requirements, it is fortunate that the global network traffic growth is slowing. According to Telegeography news, in 2012, global network traffic grew by 35%, compared with 2011, a decrease of 39%. In 2012, the peak network traffic grew by only 33%, compared with the peak traffic growth rate of 57% in 2011, but also a lot of decline.

although the global network traffic and network capacity growth is slowing, but still growing steadily. This means that Internet providers can not stop investment in network construction, and long-distance broadband companies should continue to upgrade its network.

now, the growth rate of broadband penetration in developing countries remained relatively stable, but there is still much room for improvement. In developed countries, now broadband infrastructure has become increasingly mature, new subscribers slowdown. However, due to the increasing number of online video and a variety of online applications, the speed of each network user requirements are still high. So overall, the global demand for broadband continues to rise is still quite strong.

this also requires Internet providers need to continue to maintain the existing investment in order to meet the needs of users. According to the Telegeography report, the cost of long-distance broadband companies to reduce costs. Part of the reason is that the cost of equipment continues to decrease, and the addition of new capacity on the existing network is relatively cheap.
