Heterogeneous Multi-Cluster Full Mesh Communication Practice

Explore heterogeneous multi-cluster full mesh communication practices in this 34-minute conference talk presented by Li Yang from Transwarp and Liu Wenfeng from VMware at a CNCF event. Discover novel approaches for establishing high-performance and simplified network communication between heterogeneous multi-Kubernetes clusters, enabling efficient data access for big data businesses running across different environments. Learn about the implementation of host routing in second-layer networks to ensure optimal performance, and the utilization of vxlan tunnel technology for third-layer network connectivity. Gain insights into overcoming challenges posed by heterogeneous Container Network Interfaces (CNIs), including strategies for direct communication in second-layer networks and adapting CNIs to establish vxlan tunnels with consistent Virtual Network Identifiers (VNIs) in third-layer networks. Understand the selection of Antrea as a core CNI to support configurable VNIs and its role in facilitating seamless communication across diverse Kubernetes clusters.
