Abstract

In-band network telemetry (INT) is one of the promising technologies for achieving fine-grained and real-time visibility into the network, however, it brings non-negligible traffic overhead due to the increased packet length. Several sampling methods have been introduced to reduce the INT overhead; although, the provision of satisfactory network visibility was not well investigated. In this paper, we introduce a utility-based INT sampling rate allocation scheme, namely uINT, that aims to reduce data redundancy while improving network visibility. We conducted experiments using the software switches and demonstrated that uINT reduces redundantly collected INT data by up to 15% compared to sINT.
