VFs bypass much of the hypervisor’s software switching path, delivering <strong>lower latency</strong>, <strong>higher throughput</strong>, and more <strong>deterministic</strong> behaviour than <strong>paravirtualised virtio</strong> alone — properties valued in <strong>telco NFV</strong> (vEPC, vRAN CU/DU, firewall, DPI) and in <strong>cloud-native</strong> packet workloads on <strong>Kubernetes</strong>.</p>
