Many big data business are running on Kubernetes cluster. In order to allow big data business running on different Kubernetes' clusters efficiently access each other's data, it needs a novel way to establish high peformance and simple network communitcation between heterogeneous multi Kubernetes' clusters. In the second layer network, we chose the host routing to communicate to ensure network performance. The mainstream CNI supports this function. In the third layer network, we chose the vxlan tunnel technology supported by the mainstream CNI to connect the network. For heterogeneous CNI, in the second layer network, they can communicate directly. In the third layer network, their VNI could be different that the vxlan tunnel cannot be created between the clusters, so at least one CNI can be extended by programming to adapt to another CNI, ensure that the same VNI is used to establish a vxlan tunnel between the two CNIs, we chose antrea as the core CNI to support configurable VNIs.
