The construction of 5g and gigabit optical networks in China has accelerated, and the network access rate has increased rapidly. However, in the landing application, the network disk speed limit has been encountered, and the user experience rate has decreased instead of increasing. Many netizens have had similar experiences: in work or life, they often need to download video files from the online disk to the computer. The more urgent they are, the slower the download speed is. However, opening a member can greatly speed up. Limit the download rate of non members, which is called "online disk speed limit" in the industry. The author recently encountered several videos with a length of about 4 minutes. The normal download and display time takes about 20 minutes; After opening a member, the download is completed in a few seconds. With China's accelerated entry into the information society and the increasing popularity of mobile Internet and intelligent devices, many netizens are used to storing personal data assets such as files, photos and videos on the online disk. People are also used to sharing some video transmission at work through network disk. However, with the increasing demand of users, the problem of "online disk speed limit" also appears, which greatly affects the use experience and brings trouble to users. "Network disk speed limit" is a small problem, but it is related to the sense of access of Internet users to network services. In recent years, the construction of 5g and gigabit optical networks in China has accelerated, and the network access rate has increased rapidly. However, in landing applications, the network disk speed limit has been encountered, and the user experience rate has decreased instead of increasing. Cracking the network disk speed limit and breaking the network speed bottleneck will not only help to consolidate the effectiveness of network speed increase and fee reduction, but also conducive to the healthy and sustainable development of information and communication service industry in the long run. Carefully analyzing the causes of the problem of "online disk speed limit", it is not difficult to find that this not only has the objective needs of relevant service enterprises to reduce costs and increase income, but also exposes their short board of development with single profit model and insufficient innovation power. In recent years, the growing number of online disk users has led to a significant increase in operating costs such as manpower, server and bandwidth. Some online disk service providers have begun to test the water payment membership model and force users to pay for use by making an article on the rate. The development of paying users by simply limiting the rate has gathered members in exchange for benefits in the short term; In the long run, it affects the experience, loses people's hearts, and hinders the better innovation and development of enterprises. In fact, to ensure the sustainable development of user experience and online disk service enterprises should be a virtuous circle of complementarity and mutual promotion. Providing undifferentiated rate services by relevant enterprises can not only improve the user experience, but also break through the existing single development model, accelerate product R & D and upgrading, and enhance core competitiveness. We might as well launch innovative products according to the subdivided users, attract more users to take the initiative to use, and improve the commercial value of personal online disk service business through business model innovation. It is gratifying that relevant departments and enterprises have begun to take action. In response to the problem of "online disk speed limit", in November 2021, the Ministry of industry and information technology deployed the action to improve the perception of information and communication services, and clearly proposed that relevant enterprises should optimize the provision of online disk services to ensure that the minimum rate of upload and download meets the basic download needs of free users. In order to further protect the rights and interests of users, the China Internet association organized major online disk enterprises in China to sign the self discipline Convention on user experience protection of personal online disk service business. By the end of 2021, 8 online disk enterprises have provided "undifferentiated rate" products. Some enterprises have also provided users with capacity expansion options, and the download rate of free users has been significantly improved. A small step makes a thousand miles. "A small step" to crack the network disk speed limit is also a "big step" to improve the quality of information and communication services. We expect relevant enterprises to be more proactive and continuously improve the user experience. Relevant departments and associations should also play the role of guidance and supervision, unblock the feedback channels, timely accept and properly deal with users' opinions and suggestions, transform practical initiatives into real user feelings, speed up and improve the pace of information services from "small steps" to "big steps", and constantly improve the people's sense of access to information services Happiness and security.
