Abstract
A method of caching counter values in network packet traffic sampling, includes: generating a pre-sample strobe; loading the pre-sample strobe into a counter cache; waiting for the next strobe; and generating a sample pulse when the next strobe arrives. An apparatus for counting packet values and for sampling the values, includes: a packet sampling processor including a counter cache, the packet sampling processor responsive to a pre-sample strobe so that the pre-sample strobe updates the counter cache, where a sample pulse is generated when the next strobe arrives.
