Re: Lower bound for maximum ATM bandwidth?

Good work. How did you come up with the theroetical bit rate of 134.5 MB/S
from 135.63 MB/S after considering overheads like LLC and AAL5? To figure
out why you miss about 1.5MB/S, you may need to understand the hardware
design if the overhead of TCP/IP, LLC, and AAL5 you calculated are correct.


To my understanding, some hardware design uses bit stuffing for some
special purposes, say, sync bits(inside SPE) for mux and demux. I am not
sure that is the case for you. It really depends on your hardware.
