The network control message protocol enables network administrators to accurately obtain the latest network status, in order to repair network failures in time and ensure the quality of data transmission in dynamically changing network environments. There are many applications based on the network control message protocol for detecting and diagnosing network problems on the Internet, such as the path trace tool, i.e., Trace. Path trace tools send control messages through special mechanisms and receive replies to obtain link information and transmission delays between two points. This information is valuable for analyzing network performance, troubleshooting, and optimizing route selection.
