Throughput Testing

What are people using for testing throughput on networks. Not just Canopy, but any type of network. I am looking for something I can use for poiint-to-point testing in a number of applications.

Any help is appeciated. Thanks.

You can use Ixia QCheck

Cool. Thanks. I’ll check it out.

I wrote a simple perl script that measures bandwidth. Feel free to use it.

###### Guts of program ###################################
my $data = “E” x 1024; #This is a 1 kilobyte block

print “Content-type: text/html”, “'n’n”;

my $time = time;
my $stamp = localtime($time);

my $size = 500;

for (my $i=0; $i<$size; $i++)
{
print “$data<BR>'n”;
}

my $time2 = time;

my $dif = $time2 - $time;
my $kbyte = ($size / $dif);
my $kbit = $kbyte * 8;

##### Done testing ######################################################


##### Cheesy output ######################################################
print “<BR>The whole thing took $dif secconds<BR>and was started at $stamp<BR>'n”;

printf (“Bandwidth = %.3lf KB/sec or %.3lf kb/sec<BR>'n
on a %.1lf KB transfer<BR>'n”, $kbyte, $kbit, $size);

I just downloaded Ixia QCheck, pretty neat tool.
