Ping Check-up
Ping Overview
Ping is a computer network administration utility used to test the reachability of a host on an Internet
Protocol (IP) network and to measure the round-trip time for messages sent from the originating host to a
destination computer. Ping operates by sending Internet Control Message Protocol (ICMP) echo request
packets to the target host and waiting for an ICMP response. In the process it measures the time from
transmission to reception (round-trip time) and records any packet loss. The results of the test are printed
in the form of a statistical summary of the response packets received, including the minimum, maximum,
and the mean round-trip times, and sometimes the standard deviation of the mean. Ping does not
evaluate or compute the time to establish the connection; it only gives the mean round-trip times of an
established connection with an open session.
To implement ping check-up, click
Maintenance -> Network Diagnostics -> Ping Check-up
, finish
required settings and click OK. Then Ping check-up begins and the ping info will be displayed in the ping
result box.
