Right.

Well, that is easy.

Create as many classes needed, add filters based on MARK value to put
the traffic in the correspoing classes, then simply put the connbytes
rules (-m connbytes max_bw:) together with a jump to MARK target
(-j MARK) in the mangle table.
As soon as max_bw will be reached, the packet will get marked and the
filter will put the traffic in the appropriate class.

Re[2]: [LARTC] per-session QoS

[Ben]

So maybe I'm dense, but I thought that throughput limit on classes where 
class-wide, not for each session in the class. In otherwords, if I limit 
class A to 50KB/5s, every tcp session in that class fights for the same 
50KB/5s.

Instead, I want every tcp session to have a thoughput limit of 50KB/5s. 

Maybe I don't understand your example?
