Claim 0:
1. A method of generating a plurality of telemetry flow reports in a postcard-based telemetry capable network, the method comprising:
receiving, by a network element, a first data packet including a first header;
calculating a first hash value from a plurality of first parameters of the first header;
using 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 network element;
incrementing the count obtained from the bloom filter;
determining whether the count has reached an initial counter trigger; and
in response to determining that the count has reached the initial counter trigger:
generating 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
forwarding the first telemetry flow report to a collector.
