Ping 测试
测试到任意主机的网络连通性并测量响应时间
Ping tests measure network latency and packet loss by sending ICMP echo requests to a target host and measuring response times.

什么是 Ping？
Ping is a network utility that tests the reachability of a host on an Internet Protocol (IP) network. It measures the round-trip time for messages sent from the originating host to a destination computer.
测试两台主机之间的网络连通性
测量网络延迟和响应时间
检测丢包和网络问题
Ping 的工作原理
Ping uses ICMP (Internet Control Message Protocol) Echo Request and Echo Reply messages to test connectivity.
1. 发送回显请求
你的计算机向目标主机发送 ICMP 回显请求数据包
2. 接收回显应答
目标主机以 ICMP 回显应答数据包响应
3. 计算往返时间
测量时间差并作为延迟报告
