MTR Network Link Monitoring
Monitor background
The routing strategies of the three major domestic operators are complex and the network links are unstable, which has a great impact on various industries. For example, games, live broadcasts, etc. are highly dependent on the network. Therefore, IT personnel of each enterprise need to understand the network link conditions of users in each region to the computer room or target host, and can perform targeted optimization to improve the user's business access experience.
Solution
For network link monitoring and optimization, Tingyun adopts the MTR monitoring method. It uses dial-up test clients in various regions across the country to simulate the real network of real users to initiate MTR tests on the target host - My tracerout integrates the characteristics of Ping and Traceroute. Compared with Traceroute, which only performs a link tracking test, MTR will continuously detect the relevant nodes on the link and give corresponding statistical information. It can avoid the impact of node fluctuations on the test results, so the test results are more accurate.
| Metric | Metric Descriptions | explain |
|---|---|---|
| Loss% | Packet Loss Rate | Use the final target host Packet Loss Rate to determine the overall link packet loss. If the Packet Loss Rate is high, you can contact the computer room to notify the operator of optimization by checking which hop in the entire link has a problem. |
| Send | Sent packet size | The default is to send 100 packets at a time. |
| Last (ms) | Delay of last data packet sent | |
| Avg (ms) | Average Latency | |
| Best (ms) | Best delay | |
| Worst(ms) | Worst delay | |
| StdDev | Standard deviation (jitter) | The higher the jitter, the more unstable the link is. |
| Hop | Hops | The number of route hops from the test point to the target host |
Industry reference:
| good | Normal | Difference | |
|---|---|---|---|
| Same province, same operator | Latency: <20 ms | Delay: 20~80ms | Delay: >80ms |
| Packet Loss: <5% | Packet loss: 5%~10% | Packet loss: >10% | |
| Same operator in different provinces | Latency: <50 ms | Delay: 50~100ms | Delay: >100ms |
| Packet Loss: <10% | Packet loss: 10%~15% | Packet loss: >15% | |
| Different operators | Latency: <100 ms | Delay: 100~150ms | Delay: >150ms |
| Packet Loss: <15% | Packet loss: 15%~20% | Packet loss: >20% |
