Hello!
I have 4 flows sent with a constant rate 100 pkts per second. The packet size in each flow is 1400 bytes.
After passing WRED each flow gets some packet loss and delay variation.
My question: In WRED The queue size for each flow must oscilate (it is not constant) But on tje output of the router cisco 7206 I get the constant RTT for each flow.
How can it be?
IN the attachments are the LOSS&RTT graphs for the flows
