Egress port queues of TCP flows

 

Hi Everyone,

 

 I am using qos-profile queues to allocate different shares for different flows. So the allocation as planned goes fine with UDP flows, only !

But: with TCP flows, the share is not controllable 

   1) sometime flow assigned to less priority queue takes a higher bandwidth!!

    2) when sending let say two flows, not all egress port bandwidth is exploited. For example, if port speed is set to be 100-full,  flow 1 takes 42.5 mbps, while the other one is 28mbps.

 

I was wondering if you could let me know what is going on?

 

Many thanks and best regards,
