We aim to emulate the success seen in VMs using NFV with SR-IOV, so we implement SR-IOV in cloud-native network-intensive 5G applications. Our test was undertaken within the Charging Function (CHF), a module in what is to be vOCS 4.0 for 5G. CHF is an apt candidate for the purpose of our research because it requires the lowest latency for a smooth-running vOCS.
Three metrics were considered: throughput (in TPS - transaction per seconds), latency (in milliseconds) and CPU utilization (in %).
Our solution using SR-IOV and CPU-Pinning has boosted the network throughput by 30%, in comparison with the Calico-enabled Kubernetes deployment.
