Fast TCP?

Thu Jun 5 03:20:25 UTC 2003

Glad this came up as I have been reading this paper -

Does Figure 1 in

seem reasonable ? Will 100 RED TCP flows really only fill 90% of a 155  
Mbps pipe but  87% of a 2.4 Gbps connection
and 75% of a 4.8 Gbps connection ? This seems strangely non-linear to  
me.

A more fundamental question is, is this really useful except in the  
case of very high bandwidth single flows (such as
e-VLBI or  particle physics or uncompressed HDTV).
After all, isn't the current standard practice not to come close to  
fully utilizing backbone bandwidth ?

                                  Regards
