in daily Internet access, online office or game entertainment, high network latency often brings problems such as loading cards and operation lags, and accurate network latency testing is the core premise of locating and solving such problems. Many people think that network latency testing is just a click of the test button, but in fact, to get accurate results, it is necessary to control the whole process from preparation work, test scene selection to data interpretation. This article will start from a practical perspective, step by step to analyze how to scientifically complete network latency testing, and provide users with different needs with landing test solutions.
want to get accurate network delay test results, the preparation work before the test directly determines the reference value of the data, and no details can be ignored.
1 Clean up the current network load
Beforetest, close all programs that occupy network bandwidth, such as background downloaded files, online videos, cloud synchronization services, etc. These programs will preempt network resources, resulting in false high network delay test results, which cannot reflect the real network basic delay. It is recommended to check the network occupancy rate through the task manager to ensure that the network load drops below 10% before starting the test.
2, select the appropriate test node
different test node distance, operators will directly affect the network delay test results. If it is to test the delay of daily Internet access, it is recommended to choose a node that is consistent with your own operator and close to you; if it is for a specific game or office platform test, choose the official server node of the corresponding platform, so that the data obtained is more targeted.
different usage scenarios have different requirements for network delay, the corresponding network delay test methods are also different, and the test method needs to be selected on demand.
1, network delay test
for common Internet scenariosfor ordinary Internet users, you can use professional online testing tools, such as Speedtest, webmaster tools, etc. After opening the tool, select the nearest official node and click Start Test. Such tools will automatically complete network delay test, bandwidth test and other indicators detection, and finally give intuitive delay values and network quality ratings. The operation is simple and easy to use.
2, network latency testing of game scenarios
game users are more sensitive to network delay, it is recommended to use the game's official network delay test function. For example, some online games provide server delay detection on the login interface, which can directly display the delay value of the current network to the corresponding game server. You can also execute the ping command through the command prompt, enter the Internet Protocol Address of the game server, and send 10 consecutive data packets to view the average delay and packet loss rate. The data is more referential.
3, office scenarios network delay test
for teleworking scenarios, such as accessing the company's intranet or cloud office platform, network delay testing can be carried out through the network detection tool that comes with the platform, and the traceroute command can also be used to track the path of the data packet from the local to the office server to see the delay of each hop.
complete the network delay test, you can't just look at the surface delay value, you need to conduct in-depth analysis of the data to find the root cause of the problem.
1 Focus on average latency and volatility
network delay test report, the average delay is the core reference indicator, the average delay of ordinary Internet scenarios is less than 50ms belongs to the high-quality network, and the game scene needs to be less than 30ms to ensure smooth operation. At the same time, pay attention to the fluctuation range of delay. If the fluctuation exceeds 20ms, it means that the network stability is poor, and even if the average delay is low, there may be card conditions.
2, check the packet loss rate indicator
packet loss rate is a key indicator that is easy to be ignored in network delay testing. Under normal circumstances, the packet loss rate should be less than 1%. If the packet loss rate is too high, it means that there is data packet loss in network transmission, which will directly lead to incomplete page loading, no response to game operations and other problems. At this time, it is necessary to check whether the router, network cable and other hardware devices are faulty.
the ultimate goal of network delay testing is to optimize the network, according to the test results targeted adjustment can effectively reduce the delay.
1, hardware level optimization adjustment
If the network delay test results show that the WiFi delay is much higher than the wired delay, it is recommended to connect the device directly to the router through the network cable to reduce wireless signal interference; if the router is more than 3 years old, it can be replaced with a new router that supports WiFi6 to improve network transmission efficiency and stability.
2, operators and nodes adjustment
if the network delay test results show that the delay of cross-operator nodes is too high, such as Unicom users accessing telecom servers with a delay of more than 100ms, you can contact the operator to handle the network line, or use the cross-network acceleration service provided by the operator; You can also set the DNS address in the router as public DNS, such as 114.114.114.114, to improve the speed of domain name resolution.
To sum up, accurately completing network delay testing is a complete process from preparation to analysis to application. It is necessary to do a good job of load cleaning and node selection before testing, select the corresponding test method according to different scenarios, deeply analyze the average delay and packet loss rate in the test data, and finally optimize the network according to the results. Mastering these skills can quickly locate network problems and create a smoother network experience.
