What is Reasonable? Pipeline-able @ link-rate speeds Very doable OC-48c ~= 6.25Mpps OC-192c ~= 24.5Mpps OC-768c ~= 98Mpps Pipe stage does not depend on downstream stages Counters in registers Read/modify/write possible in single stage Limits number of samplers Or, complexity increases and/or functionality decreases Disallow/Ignore packets to the same sampler within some N packets of each other Complex bypassing structures
