It isnt automatic. CBQ is a policy driven system. You get to set policy
according to local needs. Thats one of the problems you need to then
talk to the other end to pass policy (and also potentially along paths
packets are taking).
If you control both directions from a routing point then CBQ can
be a huge help as can other flow control schemes like RED (random
early drop - a simple scheme that punishes the highest bandwidth
users when congestion is occuring)
