Abstract
Systems and methods for selectively generating a telemetry report to calculate a flow or bit rate are disclosed. The methods include calculating a hash value of a packet, using it as a key to query a bloom filter, and obtaining a packet count. If the packet count reaches a trigger value, a telemetry report is generated and sent, along with the ingress timestamp, hash value, and the packet count, to the collector for calculating the flow rate (or bit rate). The collector compares the packet count and ingress timestamp of the packet of the first telemetry report with a second telemetry report, both reports being generated at various trigger values, and calculates the flow rate. If a hash collision is detected, the calculations are voided and an update to the hash function is suggested.
