Why do so many broadband upload speed is very slow? ?
With the Internet into millions of households, a true Internet era has arrived. But in China, many home users upload speed is much lower than the download speed, broadband lot 4M, 8M or even 20M, the upload speed or even less than 50K / s. This in the end is why?
1. Why should broadband upload speed limit
As early as ADSL dial-up era, upload and download speeds are unequal. Because the telephone line into the phone, three independent uplink and downlink channels, in order to avoid mutual interference, which is the ratio of the upstream bandwidth of a downlink is provided to 10: 1 ratio. That 4M broadband download speed, 512KB / s, which corresponds 50KB / s upload speed, this is normal.
However, after the fiber era, different fibers are responsible for the uplink and downlink, uplink and downlink speed not there is no problem. Even if the bureau is 100 km away from your house, upload and download speeds can peer. Technically, from the development of ADSL dial-up to broadband internet access, downlink rate has been resolved unequal problem. So the question is, why should the speed limit upload it?
In fact, broadband operators did it for profit. Starting ADSL era, users have become accustomed to the snail-like upload speed. Even now the fiber optic era, operators still by rule, do not give users upload speed too high. Operators by limiting upstream bandwidth home users, will save resources sold out to corporate customers room, so you can get more benefits.
Many people may not know is hosted in the server room requires a lot of upstream bandwidth, while the engine room of 10M upstream cost is 5-6 times 100M home broadband. Therefore, the downstream bandwidth for sale to home users, business users upstream bandwidth for sale to the practice room, has become an important means of broadband operators to reap profits.
2, upload speed limit many ills
In the early Internet environment, asymmetrical network to meet the basic needs of the Internet at that time, ordinary people generally resource-based download, upload rarely, and therefore does not require much upstream bandwidth. But with the advent of the Internet cloud, more and more people prefer video chat, like cloud storage, the photo selfie, and share video online, so crucial upload speed network.
We all know that cloud storage, video chat, sharing of resources these require a lot of bandwidth to upload and broadband operators ,, then upstream bandwidth limit, has seriously affected the user's overall web experience. Many called Fast broadband fiber to the home, upload bandwidth less than 4M. Some 8M broadband, upload bandwidth is only 0.5M, about the actual upload speeds of 50K / s, and even video chat will card.
Initially, broadband operators to limit the upload speed in order to prevent the use of home broadband business users to build websites, thus affecting their businesses green fiber, hosting and other services. This is understandable, if business users with home broadband to build the site, then the operator is not the money. But if too legislator, it will inevitably be unworthy, even injury to the user.
Speed has always been an important factor restricting the development of the Internet, especially upload speed networks, and many parts of the country simply upload speed turtle speed. In the long run, if broadband operators do not let go of limiting the upstream bandwidth will not be conducive to the rapid development of Internet products.
No upload, so what is the cloud?
