Abstract
A meter module for use in a network device comprises conformance circuitry configured to: access a first memory device storing a conformance indicator that indicates whether a permitted rate of packet traffic has been exceeded, and classify packets received at the network device based at least in part on the conformance indicator. Sampling circuitry is configured to, responsively to the conformance circuitry classifying the packets: sample events associated with at least some of the received packets, and generate indicators of the sampled events. Update circuitry is configured to: access a second memory device, slower than the first memory, to update a number of tokens stored in the second memory device, and access the first memory device to update the conformance indicator when the updated number of tokens indicates that the permitted rate of packet traffic has been exceeded.
