Re: [Cake] total download rate with many flows

[George Amanakis <g_amanakis@yahoo.com>]

The problem I am describing in this thread appears only when using 
besteffort. If diffserv3 is used (without any further prioritization by 
manipulating DSCP bits) downstream is more stable and higher in 
throughput than with besteffort.

Also, in my case disabling BLUE (by commenting out 
cake_queue_{empty,full} and all p_drop parts in sch_cake.c and cobalt.c) 
does not make any difference.
