Re: Measuring throughput

Sometimes I'm a little thick ;-)
I guess I don't understand.

If a SNMP octet counter has incremented from 24 to 48, that says to  
me that 24 octets of data have passed.  If I multiple that by 8 I get  
192 bits.  I don't understand where the difference between base 2 and  
base 10 come into play.  192 decimal or 1100 0000 binary is still the  
same number.

SNMP is returning a base 10 number, so I don't understand the point  
about collection in base 2 or base 10.

Thanks in Advance,

Se
