Why the user's network speed "broadband is not wide"? Who is the real killer?

There is no high-speed broadband infrastructure, all the Internet and other information applications will be source, this is not alarmist, and "broadband is not wide" phenomenon again let this source face exhaustion. 2011 Antitrust investigation Uproar, last year, "fake broadband" is also a concern, for broadband services, the various questions have always plagued every user, in this regard, Tencent technology field investigation visits for you to unlock the heart layer of mystery.

Last year, a report by Dcci revealed the actual average internet speed of broadband used by internet users in China, more than half of which did not reach the calibrated speed, and the netizens ' complaints exploded. So, the user's speed why "broadband is not wide"? Who is the real killer?

First understand a few concepts, this is not completely clear to many users. The broadband refers to the bandwidth in communication, the ability to transmit data on behalf of a communication line, then the user's home installed 2M, 4M or 10M refers to the speed of the broadband transmission data, also known as broadband access rate, straightforward is that we often say that the speed of the network.

Understand the concept, want to know the speed of fast, the naked eye observation is a surface method, but the user spends the money to purchase the broadband service nature to verify the product, just like the market buys the food to buy the meat, looks fresh, then must see whether weight, buys the food to buy the meat to use the scale, the net speed nature must according to the test standard

In this connection, Shanghai Telecom experts and technical people to Tencent technology, said generally speaking of 2M refers to 2 megabits per second (ie 2mbit/s), and the user's use of some real-time speed measurement software usually shows the user download speed, the unit of measurement is the number of kilobytes per second, which is 1:8 of the relationship between the two, So 2M bandwidth corresponds to the 256kb/s download speed per second, 4M corresponding 512kb,10m corresponding 1280kB. But these are theoretical rates, which are actually slightly lower.

So how much is the actual rate in line with the standard or not "fake broadband"? The person said, or 2M for example, if the normal download speed to achieve 200kb/s, there is no fake broadband. No country in the world can do 100% to provide theoretical download speed, compared to the United States, Japan, South Korea, such as regional technology relatively leading, can only reach about 90%.

And the country has already had the relevant Test standard. At the end of November last year, the Ministry of Industry officially announced the standards of the communications profession standard of broadband rate test method fixed broadband access and the "broadband rate test method users ' Internet experience" China Communication Standardization Association. Specific content you can check online, here do not repeat.

But one thing to note in the standard is that the broadband access rate refers to the transmission rate of the link from broadband service access point of broadband Access service operator to user terminal, but most of the broadband subscriber terminals are connected to the Internet terminal equipment (such as dslmodem, etc.) by means of wired connection. Because the access network is only one part of the net, so the broadband connection rate is not the same as the actual rate that users experience when they use the network service, that is, the rate between the user terminal and the Business Server.

This paragraph seems to some professional, in simple terms, is the operator to provide broadband speed to the user terminal between the other access equipment, so the actual speed and theory will be biased, and the control of the intermediate access link is a level two or three operator.

Two or three-level network operators in order to pursue higher economic benefits, do not guarantee the broadband network user experience is the main cause of "false broadband" problem. It is mainly caused by two reasons: one is to enjoy broadband sharing, the other is to force the installation of unqualified designated network.

It is understood that whether foreign or domestic, the broadband sales market can be divided into three levels: the first market is backbone broadband wholesale market, the lower backbone network operators to the top backbone network operators to buy backbone network bandwidth (export bandwidth, mainly China Telecom (micro-blog) and Chinese unicom (micro-bo)). Secondary market is the broadband wholesale market, broadband providers to backbone network operators wholesale bandwidth. The three-tier market is the broadband retail market, where broadband providers sell broadband services to users at all levels.

The experts said that the backbone of the broadband wholesale market is a very special market, and consumer relations are not, closely related to consumers is mainly the broadband wholesale market and broadband retail market. "Fake broadband" mainly appears in the broadband retail market, that is, the private broadband provider to the three basic telecommunications operators low-cost wholesale bandwidth, under the guise of Low-cost exclusive broadband, to attract the largest number of consumers to maximize profits, and too many consumers use the exclusive broadband network to make the exclusive network into a shared network, resulting in a user rate that is far below its advertised bandwidth rate.

So far, "false broadband" the real killer at a glance.

At present, Beijing has twenty or thirty two or three-level telecommunications network operators qualified SP. These SPS can to China Telecom, China Unicom, Mobile's CRC wholesale some of the bandwidth resources, driven by the interests, the wholesale bandwidth to be divided into the community to share more people use.

A seemingly simple "false broadband" problem, if really careful analysis, behind the hidden is China's broadband development in some of the big problems to be solved, only to solve these problems, can fundamentally solve the "fake broadband" problem.
