Bandwidth facing scarcity crisis, the network construction of cloud computing era should first

The U.S. ABI research company recently released its latest report on global broadband use, which shows that the number of fixed broadband subscribers in 2009 is 430.7 million, and that by 2015, fixed broadband users will grow to 548 million, of which 134 million are fibre users. People in the information Age love mobile phones and internet TV, and the demand for broadband will be even more, according to a recent article published by Time magazine. When resources are scarce, there will be oligarchs and some of them will not be able to have them, so there is a good chance that there will be a new resource crisis-bandwidth in the new millennium. Bandwidth will become the "black gold" of the new era.

Wide-band Development of "beaches" in various countries

The U.S. Federal Communications Commission (FCC) April 15 announced that the United States will vigorously popularize high-speed broadband network, and strive for the next 10 years in the United States to establish high-speed broadband network in all corners.

The plan set out the following objectives: In the next 10 years, a network of at least 100 million American households will be built at a speed of 100 megabits per second, a speed of more than 20 times times faster than existing users, and a high-speed network of 1G bits per second in public places such as schools, hospitals and government departments; The fire brigade and other public security departments have established new wireless networks to ensure that these departments can communicate and share information in emergency situations. The FCC said the United States would have the "fastest and broadest" broadband network in the world once the plan was implemented.

The European Union also urged its member States to use the same microwave FM as their mobile broadband to achieve the 2013 broadband network coverage across Europe, according to BBC News.

Japan and South Korea are one of the regions where broadband networks are developing very well, with a penetration rate of 55% and 49% per cent respectively. New Zealand's Minister of Communications and Information technology Joyce also announced March 31 last year that the government will invest 1.5 billion New Zealand dollars (about 840 million U.S. dollars) in the optical fiber high-speed broadband network promotion program.

Cautious market investment may lead to insufficient broadband

Technically, bandwidth is the ability to use a channel to transmit information. The more information you pass through a channel, the greater the bandwidth you will use. When the amount of information needed to be transmitted exceeds the capacity of the channel, there is a shortage of bandwidth.

Sometimes, the slow speed of the Internet may be caused by a full information congestion, Time magazine said in a report. But beyond that, the deeper problems lie in high prices and possible speculative profiteering. As people's demand for broadband increases, suppliers are likely to raise prices and replay the "plot" of the energy market.

So can we rely on cable or phone companies to solve these problems? In short, to some extent. But from another perspective, each broadband provider, for example, American telephone and Telegraph company, CNN, etc., may face the same problem: to increase the frequency of tolerance will require large-scale investment, and customers may be dissatisfied with their services to abandon it at any time, the company for infrastructure upgrading of the billions of dollar investment may be " , which makes it very prudent for companies to invest.

The game between optical fiber and copper cable

The ABI study shows that while countries are already pushing for fiber-optic access, the DSL (Digital Subscriber Loop) technology remains the mainstream by 2015, with a ratio of 65%, up from 24% of the fiber-optic internet.

While mobile internet access has become a choice for many users, fixed broadband has a greater advantage in home entertainment and stability, so fixed broadband will remain the mainstream option for a long time to come, but that does not prevent the rapid spread of mobile internet, Abi said.

This is evident in the United States. Verizon, the largest local telephone operator in the United States, launched an ambitious "FiOS" program (the triple Play service for Fibre to households) 5 years ago and announced an investment of $23 billion trillion, and today Verizon's "light into copper retreat" project is nearing its end. can provide users with faster Internet access speed and TV services.

But because of the high cost of the project, Verizon Communications announced on March 30 that cities that have not yet provided FiOS TVs and broadband services will not be built. Nonetheless, the project has enabled Verizon Communications to effectively confront US cable companies and provide more bandwidth than telephone companies without fibre to households.

However, many other broadband companies in the United States have been reluctant to copper cables. American telephone and telegraph companies, for example, are laying optical fibres near residential locations, but the final part of the signal entering the home is still transmitted using copper telephone lines. This is a low-cost strategy that is easy to "favor" Wall Street investors, but also limits the maximum bandwidth.

Wireless network "Traffic jam" will become normal

The Time magazine pointed out that if the cost is higher, in the next period of time, rely on optical fiber can temporarily solve the problem of bandwidth. However, the real broadband shortfall will occur in the wireless network, where demand is growing and supply is relatively tired.

The network industry is unable to meet people's demand for wireless networks, and people are seeing more and more government spending on data plans and more frequent drop-and-connect delays. At the worst of times, internet congestion is the norm, not the exception, as the traffic jams that are now being ignored in big cities, wireless service operators may use insufficient supply to earn money, and "tip" for priority access and secure broadband connections. If people want to enjoy the fun and convenience of high-speed broadband, they need to come up with a way out of the bandwidth dilemma as quickly as possible.
