许多大数据业务都在 Kubernetes 集群上运行。为了使运行在不同 Kubernetes 集群上的大数据业务能够高效地访问彼此的数据,需要一种新的方式在异构多 Kubernetes 集群之间建立高性能、简单的网络通信。在第二层网络中,我们选择主机路由进行通信,以保证网络性能。主流容器网络接口 (CNI) 支持此功能。在第三层网络中,我们选择主流容器网络接口支持的 vxlan 隧道技术连接网络。对于异构容器网络接口,在第二层网络中,它们可以直接通信。在第三层网络中,它们的 VNI 可能不同,因此无法在集群之间创建 vxlan 隧道,因此至少可以通过编程扩展一个容器网络接口以适应另一个容器网络接口,确保使用相同的 VNI 在两个容器网络接口之间建立 vxlan 隧道,我们选择 antrea 作为核心容器网络接口以支持可配置的 VNI。

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.
