hello;
i have mikrotik server installed on rb 450g ,i saw in ppp>>>profiles>>>rate limit
the following equation " formula" which is in the red rectangular,as shown below

what i can under stand is 400k is the first rate the client receive for rx & tx
after some time the rate will decrease to 250k for rx & tx and still to this limit for 8 sec
after that the rate will be fixed to 300k for rx & tx.
this is what i think, but what the benefit of the other numbers i do not know ,and am not sure how much correct what i said above about the formula and how it work.
if there is anyone can explain to me what the formula mean & how it work exactly i will be grateful.
my best regards.
