zhihu.com Ping

Ping is a networking utility tool to test if a particular host is reachable. It is a diagnostic that checks reachability of a host on an Internet Protocol (IP) network. In a computer network, a ping test is a way of sending messages from one host to another. Aside from checking if the host is connected to a network, ping also gives indicators of the reliability and general speed of the connection.


zhihu.com TRACEROUTE

Traceroute is a network diagnostic tool used to track the pathway taken by a packet on an IP network from source to destination. Traceroute also records the time taken for each hop the packet makes during its route to the destination. Traceroute uses ICMP (Internet Control Message Protocol) echo packets with variable time to live values. The response time of each hop is calculated. To guarantee accuracy, each hop is queried multiple times (usually three times) to better measure the response of that particular hop.
