basic concept:
ping:
Refers to a PING packet sent from the user device to speed points, then return immediately round-trip time from the user equipment speed points. Also known as "network delay"
Typically in milliseconds (ms) is calculated
In general PING 0 ~ 100ms is normal speed, there will be no more obvious Caton.
Test ping value method:
Powershell the input of ping [network address] to the test, the measured four times by default. If you need to test more times, put the command to change ping [network address] -t . By the end of the manual + C Ctrl.
Jitter:
Network jitter refers to the maximum delay and the minimum delay time difference, such as the maximum delay is 20 msec, the minimum delay is 5 ms, then the network jitter is 15 ms, which is mainly the stability of a network identification. Jitter smaller, more stable network.
Loss:
Data packet loss refers to one or more data packets through the network can not reach the destination. There are many possible causes, or network of multipath fading caused by signal attenuation; or loss caused by obstruction; or damaged data packets are rejected by the like. If the receiving side is lost discovery data, it sends a request to the transmitting end according to the queue number, a retransmission packet loss.
