• Calico VPP is a data plane that uses VPP as a data plane for pod traffic in Calico.
• VPP brings a lot to the table for custom networking requirements and network-intensive applications.
• The host stack can be enabled for a pod with an annotation, providing a substantial performance boost.
• Regular Kubernetes networking features apply to traffic processed through either MIF or the host stack.
• AF packet or AF XDP sockets can be used under the interface in the pod without Calico VPP, but performance is lower.
