Hi,
I want to get estimation of bandwidth even if packet drops are active.
I am using network delay box across two machines which can be configured to
introduce packet drops.
I am dropping 1 packet out of 1000. Window size is set to 32MB. Line rate is
600 Mbps.
However, I observed that iperf calculated bandwidth goes down as delay
increases (delay = round trip time between server and client).
For 0 delay, it is showing 580 Mbps ( no effect of packet drops) which is
pretty accurate with 600 Mbps line
For 20 delay, calculated bandwidth drops till 128 Mbps.
For 30 delay, calculated bandwidth drops till 106 Mbps.
For 50 delay, calculated bandwidth drops till 50 Mbps.
Is there any way using iperf to get better bandwidth estimation even at
active packet drop case?
Thanks,
Riyaz
