Abstract:
This memo describes a periodic sampling method and relevant metrics for assessing
the performance of IP networks. First, the memo motivates periodic sampling and addresses the question
of its value as an alternative to the Poisson sampling described in RFC 2330.
The benefits include applicability to active and passive measurements, simulation of
constant bit rate (CBR) traffic (typical of multimedia communication, or nearly CBR, as
found with voice activity detection), and several instances in which analysis can be
simplified. The sampling method avoids predictability by mandating random start times and
finite length tests. Following descriptions of the sampling method and sample metric
parameters, measurement methods and errors are discussed. Finally, we give additional
information on periodic measurements, including security considerations.
