What does ping mean?

Jumping ping means that the network speed is unstable, ping is the network delay, the lower the ping value, the better; ping is used to determine whether the local host can successfully exchange data packets with another host, and then based on the returned information , you can infer whether the TCP/IP parameters are set correctly, whether the operation is normal, whether the network is smooth, etc.

Jumping ping means that the network speed is unstable, ping means network delay, the lower the ping value, the better. For example, the ping value of playing CS in an Internet cafe is generally around 10, while the ping value of broadband at home is 20 or It is about 30, which is a normal network speed. But when the network is not good, the ping value will change from 20 to 100 or several hundred, and then back to 20. This is a jumping ping, which requires network to play CS. The speed is not high, but the network speed must be stable.

Ping related introduction:

PING (Packet Internet Groper), Internet packet explorer, a program used to test network connection volume. Ping is a service command that works at the application layer in the TCP/IP network architecture. It mainly sends ICMP (Internet Control Message Protocol) Echo request messages to a specific destination host to test whether the destination station is reachable and Learn about its status.

Basic information

ping is used to determine whether the local host can successfully exchange (send and receive) data packets with another host, and then based on the returned information, the TCP/IP parameters can be inferred Whether the settings are correct, whether the operation is normal, whether the network is smooth, etc. The Ping command can do the following:

① Verify connections to one or more remote computers by sending ICMP (Internet Control Message Protocol) echo packets to the computer and listening for echo reply packets .

②Wait up to one second for each data packet sent.

③Print the number of transmitted and received data packets.

It should be noted that successful Ping does not necessarily mean that the TCP/IP configuration is correct. It may be necessary to perform a large number of data packet exchanges between the local host and the remote host to ensure the correctness of the TCP/IP configuration. . If the ping is successful but the network is still unavailable, the problem is likely to lie in the software configuration of the network system. A successful ping only ensures that there is a connected physical path between the current host and the destination host.
