Claim 14:
15. A postcard-based telemetry capable device comprising:
a network interface of the postcard-based telemetry capable device configured to receive a plurality of data packets; and
a control circuitry connected to the network interface configured to:
receive a first data packet including a first header;
calculate a first hash value from a plurality of first parameters of the first header;
use the first hash value to query a bloom filter to obtain a count from the bloom filter, wherein the count represents a select number of packets received by the postcard-based telemetry capable device;
increment the count obtained from the bloom filter;
determine whether the count has reached an initial counter trigger; and
in response to determining that the count has reached the initial counter trigger:
generate a first telemetry flow report for measuring a traffic flow rate, wherein the first telemetry flow report includes the count and the first hash value, and
forward the first telemetry flow report to a collector.
