Achieving End-to-End Network Visibility with Host-INT

Abstract

So far, the In-Band Network Telemetry (INT) standard has been implemented mainly on P4 programmable switches. Observing packets as they travel through switches is knowing only half of the story. In this poster, we present the work in progress on Host-INT, an open-source solution based on eBPF and integrated with Kubernetes that extends INT support to the Linux network stack. When coupled with a P4-based Switch-INT implementation, Host-INT enables end-to-end network visibility.
