Random-detect with MPLS

Has anyone implemented CBWFQ with MPLS and used random-detect with any of the classes/queues? Is there anything special about random-detect that allows it to drop TCP v. UDP when doing label switching?

Re: Random-detect with MPLS

I have not implemented such a setup, but I am just wondering why something specially would need to be taken care when using random-detect with MPLS. Can someone throw light on this?

Re: Random-detect with MPLS

I'm basically referencing that no other headers are looked at when doing label switching. Therefore, when applying random-detect to a queue we can not easily have TCP seperated from all other traffic to maximize our chances of dropping a TCP packet to slow down the source. It appears that the commonly accepted method is to set the mark probability denominator high enough and make sure that the majority of your traffic is TCP.
