Cilium, an open-source CNI, leverages eBPF data planes to deliver exceptional performance, secure connectivity, and networking for cloud-native workloads. High-performance cluster deployments currently integrate smartNICs and DPUs providing latent compute capacities. These DPUs house power-efficient compute cores with dedicated accelerations for networking and cryptographic workloads, aligning seamlessly with the demands of high-performance CNIs. In our study, we deploy a Cilium Cluster on an OCTEON 10 DPU and benchmark key performance metrics. The focus is on analyzing Cilium's performance on DPUs equipped with low-powered ARM cores. The obtained results demonstrate significant promise, exhibiting competitive performance compared to similar tests conducted on a high-end Xeon processor. Further optimization is achievable by harnessing specialized workload accelerators, thereby enhancing cluster efficiency in terms of power, performance, and costs.
