Object
The parameter N for statistical counting on this interface.
Set to N to count 1/Nth of the packets appearing at this
interface. A sampling rate of 1 counts all packets.
A sampling rate of 0 results in the interface being ignored
by the meter.
A meter should choose its own algorithm to introduce variance
into the sampling so that exactly every Nth packet is counted.
The IPPM Working Group's RFC 'Framework for IP Performance
Metrics' [IPPM-FRM] explains why this should be done, and sets
out an algorithm for doing it.
