for some time Jim Gettys on his blog is writing a lot about problems caused by buffers, queues and other congestion avoidance mechanisms. you should really read about them. especially, if you’re in this group that believes big buffers solve all of the problems, and dropping traffic is absolute evil. nowadays it should be treated as absolutely normal thing - in most of the real life cases.

on the upcoming, sixth PLNOG we may be able to tackle this problem (if there will be space in agenda), and have a shot at myths and legends related to network QoS. and yes, agenda will be out there soon, we’re just closing down last preparations.
