Ping Math to Kbps
Can one of you technical math minds figure this out for me . . . .
I am trying to find my connection speed to the internet
I get back statistics that say
8 packets transmitted, 8 packets received, 0 loss
120ms avg round-trip

Show me the math please to convert this to actual Kbps in a 768Kbps to
3Mbps DSL connection

Thanks
Paul

You don't use ping for "bandwidth" testing. The ping time gives
you just ping time latencies.... which may or may not be interesting.

tester... e.g. [url]http://www.dslreports.com/speedtest[/url] or
[url]http://www.speakeasy.net/speedtest/[/url] or [url]http://www.speedtest.net/[/url]

(there are many others)

Weeeell, 64 BYTES in 60ms (half round-trip) translates to 8.5kbps :P

I'd suggest you try [url]http://www.speedtest.net[/url] for a more realistic

Re: Ping Math to Kbps
The reason I asked this question:
I had been using the Verizon Speedtest because the connection
seemed so slow. Sometimes it read under 350Kbps and 5 minutes later
1.8Mbps. I called Verizon to check for problems. One test they had
me do was the PING of google to see how fast the connection APART FROM
their test. They still have not solved the fast/slow thing. I was
using:
[url]http://infospeed.verizon.net[/url] for a Verizon DSL connection

Thanks for the info that I am trying to compare "apples and oranges" -
Not sure what the Verizon tech was doing then???

In addition to the online speedtests, you can use 'bing' as well. You
can install it with:

zypper install bing

and then:

man bing

It's all of 50KB in size . . . :-)

Do you drive a car? How fast can you drive from... I dunno, how
about Bethpage (Long Island, NY) to Saint Louis, Missouri? Don't
you think it might have something to do with the amount of traffic
on the roads? Simple point - Verizon provides a connection that
might be capable of 3000 Megabit/second but "caps" (limits) it to
some value that you are paying for - perhaps 3 Megabit/Second
(so that you don't hog all of that 3000 Megabit), and then they also
sell the same service to a million of your neighbors because they
know that everyone won't be going to school/work/shopping at the same
time. Using these numbers, only 1000 people can get their "full"
bandwidth at any given moment, and if more people than that try, it's
like a traffic congestion on the roads - traffic slows down.

If you pay more, they might be able to offer a "faster" connection...
until they sell the same service to a million other people.

You gauge speed by timing how long it takes to transfer a substantial
amount of traffic. You want to grab something large enough so that
you can time it on your watch - perhaps the source of the latest
kernel from ftp.kernel.org which is about 50 or 60 megabytes, and see
and see how long that takes. The idea is a large file, so that you
