In-band Network Telemetry Task Orchestration based on Multi-objective Optimization

In-band network telemetry task orchestration is to study how to reasonably select business flows to carry in-band network telemetry tasks to cover all necessary switches and ports. An inappropriate orchestration scheme not only fails to meet the requirements, but may reduce the performance of network telemetry. This paper proposes a multi-objective optimization-based in-band network telemetry task orchestration algorithm, while taking into account both the aspects of telemetry: freshness and intrusion. The experimental results show that the proposed scheme outperforms in terms of freshness and intrusion.
