Re: Question about propagation and queuing delays

This is interesting. This may sound like a naive question. But if queuing delays are so insignificant in comparison to other fixed delay components then what does it say about the usefulness of all the extensive techniques for queue management and congestion control (including TCP congestion control, RED and so forth) in the context of today's backbone networks? Any thoughts? What do the people out there in the field observe? Are all the congestion control researchers out of touch with reality?

Co-operative congestion control is like many other things where you're better off without it if most of "somebody else" is using it. TCP does not give you optimal performance but tries to make sure everybody gets along. Pete
