Is the faster the internet speed, the lower the latency? 20

There are at least two basic concepts involved in your question, first, how latency is generated, and second, how the speed is limited. These two basic questions are very complicated and lengthy to explain clearly, so choose the main points to explain briefly, and if you are interested, you can refer to the relevant materials yourself.

Network delay simply includes two factors, one factor is the delay caused by the transmission speed of the signal in the medium, in general applications, it is assumed that the transmission speed of the copper medium is about the speed of light, and the other factor is caused by the data network using the working mode of storage, the delay caused by the transmission speed is fixed, and the delay caused by the storage mode is variable, not possible, the storage mode introduces the concept of queues, and the data that cannot be processed in real time enters the queue. The memory of any device cannot be infinite, so when the queue eventually overflows, the overflowed data will be discarded. At the application level, the most common occurrence is ping latency fluctuation (the device is overloaded and data enters the ** queue) and even packet loss (queue overflow and data is discarded).

For the limitation of network speed, either IP speed control, or MAC speed control, the router application layer gateway uses IP speed control, by counting the number of packets containing a specific IP header for rate control, the switch uses MAC speed control, by counting the number of data frames containing a specific MAC for rate control, obviously, whether it is packet speed control or data frame speed control, it is inevitable to introduce the concept of **queue and drop) (because this is one of the applications of storage**).

Now back to your question, theoretically, there is no strict proportional relationship between network speed and latency, but in practice, we often find that a high-speed line will have a lower latency when accessing a specific remote device (to be precise, the remote IP stack) than a low-speed line accessing the same remote-end device. The existence of this phenomenon is influenced by many factors, but the main factor lies in the speed control mechanism. Corresponding to a relatively high rate, the device has a larger tolerance when counting packet frames, and the chance of data entering the queue is lower, and the delay caused by storage is not obvious.

Actually if you're on the same line, like the original 4m

AD upgraded to 8M

ad, there will be no noticeable change in the average latency of accessing the far end. Don't take 4m

AD followed by 20m

Optical fibers are compared, and the line performance and link equipment are completely different and not comparable.

Not necessarily. This is generally determined by the operator. Generally speaking, the lowest latency is telecom, but now the mobile Unicom in most areas is also very good, and the network speed.

Soon. Other small broadband providers are more unstable, sometimes good and sometimes bad. It is recommended to play the game by telecommunications, and you don't need a very fast internet speed.

Network latency. High, it may be due to aging routes, which seriously affects the network quality. It is also possible that the network cable or network port is faulty, resulting in poor network transmission. In addition, assuming that the 10M network is operated alone, there will be no problems with the network quality, and if it is divided into several parts, the network will naturally deteriorate.

If it is a single-person wireless router.

It is possible that the password has been stolen, and you can try changing the password. <

Summary. Hello Oh Kiss Low latency but slow internet speed 1The router selected router should at least meet the requirements of supporting gigabit network and dual band, gigabit refers to the bandwidth of 1000m, and dual band refers to two wireless signals:

The advantages of AND are fast speed, low latency, and not easy to be interfered with, but the coverage is insufficient. The advantage is that the ability to penetrate the wall is strong, the signal is farther and more stable, but it is easy to be interfered with, so only the combination of the two can be more convenient to use. Routers get what you pay for, Xiaomi, Tengda, TP-Link if you are on a tight budget, and ASUS, Netgear, and H3C if you are not nervous.

2.The network cable selection is divided into four types: Category 5 cable, Category 5 cable, Category 6 cable and Category 6 cable, the following figure is the detailed parameters of several different types of network cables.

Category 5 lines have been gradually eliminated by the market because they cannot reach the broadband transmission speed at home, so now for decoration, at least more than Category 5 lines should be selected. 3.The WAN port of the router is the exit of the network output, the larger the entrance, the more network signals will pass, if your broadband is 200M, and the WAN port is indeed 100M, then the network it can pass through can only be 100M, then your home network speed is limited to 100M, so the WAN port of the router should choose a large one, and the Gigabit port is the best.

Class 5 line Lao Tong because it can't reach the broadband transmission speed at home, has gradually collapsed and been eliminated by the market, so now decoration, at least choose more than 5 types of line.

I connected directly via a network cable.

Is there a router installed on the network cable?

No. Kiss Your installed broadband megabytes are small!

100 trillion, it was good before, but suddenly it was like this, and it was very slow to open the web page.

Kiss 100 trillion is not high, maybe your area There are many people using the Internet during that time, so it leads to a lot of stuck!

It will be fine in a while!

Network latency of less than 100ms is considered normal.

30ms: Extremely fast, almost noticeable lag, playing any game is very smooth.

50ms: Good, normal gameplay, no noticeable lag.

100ms: Normal, adversarial games can feel a noticeable lag with a slight pause.

4. >100ms: poor, unable to play normally, stuck, packet loss and disconnection.

Calculation method: 1 second = 1000 milliseconds (e.g., 30 ms is a second) <>

Nowadays, whether it is office or study, we can't do without computers, but computers may occur in various situations under long-term use, for example, some users have recently encountered the problem of fast network speed but high latency, how to deal with it? Let's share with you the solution to the problem that the network speed is obviously fast but the latency is high.

Reason:

First, the link problem between the game operator and the broadband operator, this problem can not be solved by the user, if this phenomenon often occurs, you can call the operator's repair report**, so that the operator can check whether there is a problem with the intermediate equipment.

2. Server problems, network servers (including operator DNS servers) resource tension peaks lead to insufficient processing capacity and delays.

Third, the problem of its own computer processing capacity, the terminal computer is old and the processing power is insufficient, resulting in delay.

5. NIC problems (including drivers).

Workaround:

First, for the line problem, this is not for the user to solve, you can try to call the operator's repair ** to detect the line.

2. For server problems, you can try to use an online game accelerator, which can optimize the lower line to reduce game latency.

3. You can use the computer manager to test the hardware and check whether the overall performance of the hardware is too low. With the continuous upgrading of games, the demand for computer hardware is also increasing, and the hardware can be appropriately upgraded to solve this problem.

5. If the network delay caused by the NIC or NIC driver is delayed, you can try to update the NIC driver.

2. If it is not an exe driver, you can do the following.

Start Menu, Search, Go to Device Manager, then find "Network Adapters", click on it, right-click on the device you want to update, and then click on "Update Driver" as shown below.

Observe if there is any improvement after updating the driver.

The above is the solution to the high latency of the network speed, which is obviously very fast, and if you encounter the same situation, you can participate in the above method to solve it.
