Traveling Through a Network
Packets travel through the network by a series of
servers that create a web-like path from computer to computer. This type of
path makes it possible for a packet to choose from many different routes to
find the quickest one. If a server is busy, it can reroute to find the next
best route. Google.com took a max of 335ms to send an echo reply, Yahoo.co.jp
220ms, and News.com.au 20ms. Distance-wise, google is the closest, and Australia
is the furthest by 15183.75 km. It doesn’t seem that distance has anything to
do with how fast a site pings because the Australian site only took 20ms.
However, the traceroute command shows that Google.com was significantly faster
at each hop clocking a max of 25ms.
Using the traceroute command, one can identify the
server (IP) blocking the packet and notify the ISP of the issue. The route can
also show if your packet takes the most efficient path available. Using the
ping command, one can determine if the site is down or if there is some
communication error with that particular site rather than the entire internet. Two
possible reasons why a ping request or traceroute command might time out or return
with an error message are that the server is busy or down and the packet needs
to find a new route, or the website is down and cannot send the echo reply.
Knowing the issue is the first step to correcting it and returning to your day.
