If you are doing 115 Mbps then in 5 minutes you will count 115 * 5 * 60 / 8 = 4312 Bytes However a 2^32 counter can only count 2^32 / 10^6 = 4295 Bytes So yes, it will overflow. On a somewhat related topic Martin, your graph at http://www.beecroft.co.uk/choppy.png shows the classic case of this problem. I am wondering if I can get permission to use that graphic in the JFFNMS docs? You've removed all the identifying information which is good. It will probably help others touse a concrete example. If it can be used, it would go at the bottom of http://www.jffnms.org/docs/errors.html which describes this problem. - Craig -- Craig Small GnuPG:1C1B D893 1418 2AF4 45EE 95CB C76C E5AC 12CA DFA5 Eye-Net Consulting http://www.enc.com.au/ MIEE Debian developer csmall at : enc.com.au ieee.org debian.org ------------------------------------------------------- This SF.Net email is sponsored by the 'Do More With Dual!' webinar happening July 14 at 8am PDT/11am EDT.
