DPU/Host CNI

DPU/Host CNI integrates Data Processing Units (DPUs) with Container Network Interface (CNI) plugins on host systems, offloading network processing to hardware accelerators to improve performance and security for container workloads.

DPU/Host CNI leverages specialized Data Processing Units (DPUs) to offload packet processing, encryption, and traffic management tasks from the host CPU, enhancing network throughput and reducing latency for containerized applications.

By integrating CNI plugins with DPU hardware, this approach accelerates network functions such as packet forwarding, QoS enforcement, and secure tunnel termination without burdening CPU resources, while maintaining compatibility with Kubernetes and other orchestrators.

Administrators define DPU/Host CNI configurations through custom resource definitions (CRDs) and manage lifecycle events via the CNI operator. Proper firmware updates, driver compatibility, and security policies are essential to ensure stable and secure operation.
