Hi Alfredo

Having a 10 Gbps interface and  inter-packet-time = 0 nsec would give us “full 
speed”.
I agree, increasing the inter-packet-time would throttle the transmitted volume.

Choosing the right value for it is the problem.
This value must be calculated with the average packet length of a pcap file and 
the desired volume.
Do I understand this correctly?

Or is there another, simpler way to achieve this?

Regards,
Marcel

Hi Marcel
adjusting the inter packet time should actually work, increasing it for getting 
5 Gbit

[--inter-packet-time|-I] <nsec>

Please let me know if you are able to make it work, or if you need something 
different.

Alfredo

Hi,

we have pcap files collected at 1 Gbps.
Now we want to replay them on a 10 Gbps interface at different
"transmit rates", e.g. 10 Gbps, 5 Gbps, 1 Gbps, 500 Mbps - meaning
the sent data volume according to those rates.

Only adjusting the inter packet time would not help, right?
Is there a way to easily achieve this?

Thanks in advance.

Regards,
Marcel
