find a tool to test packet loss and throughtput

dreams · 08-03-2007, 09:18 PM

Hello,

Is there any tool(software) to test the packet loss and throughput of Ethernet? Now I use netperf to test throughtput, and I cannot get how many packets which it send. I do need to find a tool which can test Ethernet throughtput and a tool which can test packet loss.

Any suggests and helps would be appreciated. Thank you so much

Environment:
2 servers are connected by crossover cable directly.
NIC: Intel PRO/1000 (both server are same)

For packet loss, how about ping?

ping is a good choice, but
I need a tool which sending packets as fast as possible, does ping have this feature?
thanks PatrickNew

On Linux man is a good choice to start ;-)

man ping

Code:

-f     Flood  ping.  For  every  ECHO_REQUEST  sent a
              period  ``.''  is  printed,  while  for   ever
              ECHO_REPLY  received  a  backspace is printed.
              This provides a  rapid  display  of  how  many
              packets are being dropped.  If interval is not
              given, it sets interval to  zero  and  outputs
              packets  as fast as they come back or one hun‐
              dred times  per  second,  whichever  is  more.
              Only  the  super-user may use this option with
              zero interval.

Thank you framp, but "ping -f" is still not fast enough. when I ping a server 10000000 times, it last so long time.

Code:

ping -f -s 64 -c 10000000 xxx.xxx.xxx.xxx(server ip)

So I need a professional network test tool to send packets floodly even than "ping".
Thanks
