In virtualized networking environments, understanding frame latency is essential to ensure performance and reliability. svtrace and svtrace-ansible are specialized tools designed to compute the latencies of network frames, particularly within virtualized infrastructures. Leveraging eBPF (via bpftrace), these tools offer precise measurements of frame transit times between virtual machines, hypervisors, and physical interfaces, providing critical insights into the behavior of virtualized systems.

This presentation will showcase how svtrace tools are used to analyze latency in real-time, streamlining performance diagnostics for developers working on networked applications. These tools are part of the SEAPATH project, a virtualization platform developed under LF Energy.

SEAPATH focuses on creating open-source solutions for high-reliability and real-time automation systems, providing the foundation for next-generation virtualized environments.
