I would argue that 'congestion' is a characteristic of the network  
(not an individual flow) where the offered load exceeds the network's  
capacity at some point.   Flows are affected by congestion initially  
by delay, marks, and then packet loss as the congestion level  
increases.  (Different types of flows will have different tolerance  
levels for these effects.)
