网速变慢原因分析(Cause analysis of slow speed)

网速变慢原因分析(Cause analysis of slow speed) Analysis of causes of slow speed The Internet has become indispensable work and leisure in our lives, but in daily work often encounter the netizen letter to ask why the slow speed of the slow speed; how to do and other issues. To solve these problems, first we start from the understanding of some concepts. First, some basic concepts about speed 1, speed and bandwidth Speed usually refers to the actual users network access speed, the theoretical speed of the network bandwidth is usually expressed in. As we often say that the 1M bandwidth is 1024 Kbps (Kilo bit per second kilobits per second). The so-called network speed, network transmission speed per second, it is often said that the upload speed and download speed, BPS said that the number of transmission per second. Here is another kind of representation, namely KB/s (Kilo Byte per second kilobytes per second), because of 1Byte=8bit, so 1M bandwidth can also be expressed as 128KB/s, is a form of download or upload speed of our common. 2, why is the speed limit Influenced by the network transmission medium and the technical level, so the speed will be limited. As before we through the telephone line, using Modem (modem) dial-up, speed of 54Kbps, now most of the users through the ADSL access to the Internet, often in the 1-3Mbps speed (provided with local operators, the service related) optical fiber, it can reach 10M or 100M. 3, what is the flow Flow refers to the total transmission data within the specified time. Traffic is generally calculated on a monthly basis, calculated as: page size (or download files) * browse number = total flow. For example, if the 10Kbyte of the page, browse 1000 times in a month. The flow rate is 10Kbyte * 1000=10000Kb=9.77Mb Two, why the Internet speed will slow down The Internet slow for many reasons, have their own computer problems, there may be a transmission medium and routers, servers and other problems. The author summarizes some common si
