Nirmal,

It would appear to me that you are trying to measure I/O traffic 
using time, is that correct?

Have you checked to see if the device you are using supports 
some kind of session traffic limit rather than trying to use a 
session time limit ?

If my presumption was correct and there is no other way of doing 
what you want automaticaly, this may be a last resort :

If your equipment provides bandwidth limiting, you may be able 
to use successive approximation, by using the maximum amount of 
traffic over a specified amount of time to determine the 
session time limit. You could then calculate how much traffic 
is left and allow the next session to connect for the ammount 
of time it would take to exhaust that amount of traffic. I have 
not looked into the specifics of how you could do this, but if 
you are using some kind of SQL for accounting it shouldn't be too 
difficult.
