(The interface of pingplotter is simple, and it combines the two expressions of data and graphics. Compared with other inspection and analysis tools, its inspection and analysis results are more intuitive and easy to understand. PingPlotter is characterized by a multi-linear trace-routing program, which can quickly alert the bottlenecks and problems in the network at that time. For example, compared to TraceRT in Windows, it has the speed advantage of the information being reacted together.)
