In complex enterprise network environments, some applications need to isolate traffic between frontend services and backend services in different VLANs, or need to provide dedicated, low-latency data channels for high-performance data transmission, such as database synchronization and message queues.
Based on Multus CNI, AKE implements Pod multi-network access for workload clusters (VM-based workload clusters). Multus CNI is a mature addon in the K8s community. It is maintained by the CNCF Network Plumbing Working Group and supports adding multiple network interfaces to Pods. AKE connects Pods to multiple independent network planes by configuring NetworkAttachmentDefinitions. It implements Pod secondary NICs based on Macvlan technology, providing near-native network performance and strict layer 2 isolation. Users can manage Pod dedicated network configurations through the visual interface, and can also dynamically enable Pod multi-networking after cluster creation without rebuilding the cluster.
