Understanding TTCP Output

davidhuynh5 · ‎09-30-2010

Below is the output for TTCP from RouterA to RouterB.

I am interpeting the ouput as RouterA has sent 67mbps of data to RouterB in 39 seconds and averaging 1.6mbps? Is this correct?

What does the 2626 I/O calls mean? Thanks in advance.

ttcp-r: buflen=32768, align=16384/0, port=5001
rcvwndsize=32768, delayedack=yes tcp
ttcp-r: accept from 10.0.253.10

Hi David,

Checking this link below:

It appears the receiver i/o calls equate to the number of packets received.

Regards, Ash.

thanks, but that article was still a little unclear.
