Use WinMTR software to simply analyze, trace, and detect network routing conditions.

Software download address: http://downinfo.myhostadmin.net/vps/WinMTR.rar After unzipping, run it.

Enter a domain name or IP, and click the start button to begin execution.

Parameter explanation:

Loss: Loss rate

Sent: Number of packets sent

Recv: Number received

Best: Fastest response time

Avrg: Average response time

Worst: Worst response time

Last: Last response time

Mainly look at these parameters: Loss, Best, Avrg, Worst. For example, in the image above, taking 百度 as an example, a Loss of 100 can basically be ignored; this is because route data cannot be obtained, so it is 100%. Mainly look at the Best and Avrg data of other routes; generally, values within one hundred are normal. In addition, check whether the last route IP is the IP that the domain name points to; if not, it indicates a problem.

Example 2:

As shown in the image above, although the packet loss rate looks very high, looking at the later routes, the data packets sent were all received, indicating that the link is normal. Some routes have imcp packet protection, so a high packet loss rate appears, but it is actually normal. The response value of over one hundred is because this IP is in the United States; due to its physical location, the response time is generally around 200 milliseconds.

Summary: Generally, only look at the Sent and Recv values. If the sent and received data are basically equal, it indicates that route packet transmission is normal. Next, look at the Best, Avrg, and Worst data; generally, a response time within 100 is normal. If the packet loss rate is very high and the response time is very large, you can look at the route IPs before and after. You can query the location of this IP online, and you can basically determine where the network delay exists.
