Hello,

I was going through rfc 2819
<http://www.ietf.org/proceedings/97apr/97apr-final/xrtftr72.htm>and found
that utilization formula is given as follows

         This object can be used as a reasonable estimate of
         10-Megabit ethernet utilization.  If greater precision is
         desired, the etherStatsPkts and etherStatsOctets objects

         should be sampled before and after a common interval.  The
         differences in the sampled values are Pkts and Octets,
         respectively, and the number of seconds in the interval is
         Interval.  These values are used to calculate the Utilization

         as follows:

                          Pkts * (9.6 + 6.4) + (Octets * .8)
          Utilization = -------------------------------------
                                  Interval * 10,000

         The result of this equation is the value Utilization which

         is the percent utilization of the ethernet segment on a
         scale of 0 to 100 percent."



However wanted to know the formula for 1G Ethernet ports. Has it been
developed?

Thanking in advance
Best Regards
Madhumala
