Something that broadband is not up to standard may you know?

The “News Tea Fan” promoted this morning has aroused heated discussion among the participants. Xiao Bian has seen a lot of comments and comments, mainly focusing on the “Ministry of Industry and Technology to rectify the problem of broadband resolution rate”. It is true that nowadays the lack of life of young partners can be overcome, but lack of electricity and no net is unbearable. However, do you know how broadband can be considered non-compliance? Why does it fail?

FTTH or FTTB

Now most of the broadband is nothing more than two kinds of FTTH or FTTB, the so-called FTTH full name Fiber To The Home, as the name suggests is a fiber directly to the home, with a cat device dial-up Internet access, exclusive bandwidth for the unit; FTTB's full name is Fiber To The Building, which means "optical fiber to building." FTTB uses dedicated access without dialing. It uses the optical fiber directly to the building, and then uses the twisted pair to receive the user's mode. It belongs to the dedicated line access, users do not need dial-up Internet access, boot can enter the Internet.

To be more straightforward, FTTH requires dialing (whether it is using computer dialing, routing dialing, or optical cat built-in dialing), and bandwidth is exclusive. FTTB is commonly known as residential broadband, and wiring can be used (maybe need to log in to the web page to enter Account), but the bandwidth is shared.

The exclusive nature is the best. This is also the solution used by the three major operator-based broadband providers. Even ADSL is actually exclusive, so that it is not interfered by others and the natural broadband is stable. The broadband in the community can be much more, all are shared in any case, the nominal broadband speed is very easy to be influenced by other users in the building to use the network, so it is easy to appear unable to reach the target situation.

Broadband speed test to know

Broadband speed measurement is the most intuitive way to check broadband, and Xiaobian has previously recommended websites for speed measurement, such as http://. This site can automatically determine the location of the site and use the corresponding local speed server to measure the speed. However, the test results of this site can only be a reference and cannot be used as a basis! Because broadband operators only recognize their own speed results, Xiao Bian believes that this is indeed understandable, after all, the speed of the network is difficult to judge in absolute terms, the impact of various other factors are included (server area, technical differences).

Xiao Bian also posted the official speed website of the collected operators. The small partners in need can give it a try:

China Telecom

China Unicom

China Mobile

Websites everywhere have their own speed pages and cannot provide all of them effectively. For example, Beijing is:

Great Wall Broadband

There are still some broadband companies across the country that can't do everything one by one. There are comments in the comments area. Xiao Bian can help you.

Another point is that if your network bandwidth test result is more than 80% of the nominal speed (downstream), it is basically an acceptable result. Not only that, in fact, in order to deal with speed failure, some broadband operators actually open the broadband speed to you in the background, which is about 120% of the time of signing (200Mbps of the small compiler's actual speed is 250Mbps). This is to avoid the occasional connection of broadband. Smooth question. Pay special attention to the use of small partners above 100Mbps bandwidth, pay attention to whether their light cat is Gigabit, whether the router / switch is Gigabit, the wireless part is not 802.11ac specification, otherwise it can not reflect the actual capacity of 100Mbps broadband.

Is broadband not equivalent to speed?

I do not know if everyone noticed that broadband speed is not equal. We often say that the so-called 100Mbps bandwidth actually refers to the downlink bandwidth. The low uplink bandwidth is 1:2 in most areas, and most areas are 1:8 (or even 1). : 10), 100Mbps uplink, downlink is about 12.5Mbps, and there are 50Mbps (rare). Only the bandwidth of the private line can achieve a 1:1 ratio, but the price is not affordable to the family and it is meaningless.

Poor speed is more than an operator’s business

The speed of the network is sometimes not good, and it is not entirely a problem for broadband operators. Xiao Bian summed up the current impact of speed on the network:

First, the background rogue program, all family buckets will run data in the background, there is no good limit method, in short, is to install as little as possible;

Second, all kinds of downloading software will be uploaded after startup, and the bandwidth will always be squeezed, resulting in many applications where the networking speed of other applications is not ideal.

Third, many routers have the behavior of collecting data. This Xiaobian has no way to say one by one. After all, the situation is different. On the empirical theory, the reliability of traditional router manufacturers is higher.

Fourth, there is insufficient connectivity between broadband and servers. Many players who play games know that sometimes they have to replace the server to find the one with better connection speed. This kind of influence basically belongs to an uncontrollable range, and anyone who can't say what the problem is is that they can't just blame the crime. Business

Fifth, the impact of response time, especially game players, is not that the "width" of broadband affects the gaming experience, but more importantly, PING - the response time. Does it mean to see if the Xiaobian has a “PING” test value on the left side of the speed chart? That is the response time of broadband. The smaller the number, the shorter the communication time with the server and the faster the response. The online game is naturally better.

Sixth, it's easy for Xiaobai to understand 100Mbps as 100MB/S, MB/s as megabytes per second, and Mbps as megabits per second. The former refers to the number of bytes transmitted per second. The latter refers to the number of bits transmitted per second. Byte is the number of bytes, bit is the number of bits, in the computer every eight bits is a byte, which is 1Byte=8bit, which is a 1:8 correspondence. So 1MB/s is equal to 8Mbps, so it's easy to understand.

Seventh. The FTTB-like shared network is naturally slow. Everyone is using it. Even if it is 100MMbps broadband, there may be dozens of people watching movies, files, and games at the same time. Can you get up fast?

In any case, Xiao Bian is very much interested in seeing a higher quality network environment. Now, leaving the Internet is almost an era of illiteracy, and no one can escape.
