"Prime Minister Tucao network speed slow" thing, some time ago in the network downtown uproar. That our broadband in the end is not slow, expensive, operators should not back this black pot? JAVA Jun today to Tucao under.
Depending on whether the internet is slow or not, there may be a way to judge first. We first look at ordinary people's point of view, how to judge the network is not slow.
Operators that you open a 100M broadband, it is estimated that it is not going home all day to take a speed measurement software speed it. You open the broadband is for the Internet, in order to see the video, in order to play the game, in order to download a small movie, and occasionally also used YY, cut a diagram to the circle of friends to show off your home 100M bandwidth. No matter how you use broadband, broadband is just a channel, you need is the data obtained from the Internet. Therefore, judging fast network, the user's most direct feeling is the speed of access to data from the Internet. This is actually the same speed that the operator tells you is not the same thing. Operators tell you that your home broadband is 100M, referring to your home to the carrier network speed is 100M, but to the carrier network and the Internet that is two different things.
Let's give a simple example. Internet is like a city, you go out to the door Wal-Mart it? The average person downstairs or in the district, out of the district have to sit a car to Wal-Mart it. This district is the operator's access network (which can be fixed broadband, it can be 4G), and out of the district's main road that is the backbone, Wal-Mart is a data center. All the data you get from the Internet is delivered from the data center. You need to go through the access network to your home network first. Operators tell you 100M, but your home to the district speed is 100M, which is still far from Wal-Mart yet. More troublesome is that sometimes you want to buy things in Beijing, but your home in Shanghai, have to send courier, it is even slower. (Think of operators to tell you clearly what this 100M is, or is not it easy)
So we can see that the speed is not fast, not only depends on the access bandwidth, but also depends on how far the data is from you. The farther the data leaves, the longer the path will be and the more congestion will be caused. The bandwidth of the access network and backbone network is very high at present (the road is very wide), ranging from dozens of G to dozens of T, but the bottleneck often appears in the connection place (intersection), such as your home Community exit that road, such as the elevated intersection, such as Wal-Mart's door. You should now be able to understand that, even if the operator gives you 1G of bandwidth, in fact, not much use.
So this problem can not be solved? If your wife let you buy salt package, you have to run Wal-Mart, it is estimated that you have not finished eating meal back. In fact, operators and content providers (that is, Wal-Mart) is also to solve this problem, think of ways to get data closer to your home, for example, next to your community to open a community store, then this is the CDN (content distribution Network). With the community shop, you finally do not have to Wal-Mart to run the bottle of soy sauce, the speed greatly improved, to catch up with the meal. Therefore, CDN is also a very important system on the Internet nowadays. Like the blue floods listed in the United States, the domestic listed websites are all doing this. Many Internet companies are starting to make efforts in this regard.
But this is not fast enough, in order to buy a bottle of soy sauce run across the cell door is also very tired, in particular, some of the community itself is very large, ran to the door had 10 minutes to the community shop had 10 minutes team. What you hope is downstairs to buy, right? That can not be closer to the content of the user, directly downstairs in your home to open a canteen it? Sorry, I can not do it right now. Because the current structure of your home district, can not shop. You must be weird, why can not we open it? In fact, this can not be completely strange operators, because your home was originally built when the community did not expect to shop, no place. This is a big problem now facing the network, too rigid, inflexible, not open.
Therefore, to solve the problem of the speed at which the premier said that the Internet is actually more than just a matter of access bandwidth. In fact, blindly increasing the access bandwidth will only make the situation even worse, because such a small number of users will cause a lot of congestion. To solve this problem, the most fundamental thing is the revolution in network technology, to make the network more intelligent and more open, so that the content is closer to the user. For example, the content sinks to the access network or base station Your home downstairs).
Finally, let us look at your expensive. Really expensive, a pile of data can explain. Can it be cheaper? That depends on the cost can not go down. To be honest, operators actually no way, who let those equipment so expensive, so complicated maintenance, take a look at all the equipment manufacturers earn pours know. Why equipment manufacturers that earn? To put it plainly, technical barriers. Therefore, to cut prices, the same is to rely on changes in network technology to break the monopoly of traditional equipment.
In any case, the black pan operator must back, who let him accept our money, or quickly think about how to use technological change to solve this problem.
