AI Technical Summary

Technical Problem

The prior art is difficult to effectively optimize data export in both high data rates and low data rates network telemetry data streams, resulting in excessive load on the central acquisition node.

Method used

Adaptive network telemetry export method is adopted to receive data packets, classify them based on predefined rules, and export telemetry reports at different export rates based on classification results. Specifically, data packets not classified as congested are derived at a lower rate, data packets classified as congested are derived at a higher rate, and the merged export rate is limited to a certain threshold.

Benefits of technology

It effectively reduces the data load of the central acquisition node, ensures optimization of network performance, and is suitable for high data rates and low data rates.

Abstract

A network device and method for exporting network telemetry data are disclosed. The network device is used to: receive at least one data message suitable for telemetry export; classify the at least one data message based on predefined rules to obtain a classification of each data message; generate a telemetry report for each data message in the at least one data message; and export the at least one telemetry report at a certain export rate based on the classification of each of the at least one data message. In this way, a dynamic adaptive telemetry data export strategy is provided, thereby ensuring network performance while minimizing the overhead generated by executing the measurement mechanism.
