Connection and service discovery are usually key challenges for multi-cluster management, existing solutions such as Submariner introduce pre-conditions for public IP and specific CNI. This is problematic for projects like the "East-to-West Computing Resource Transfer Project" where clusters lack public IPs and have diverse CNIs due to different ownership. This session introduces a solution to establish an independent and unified parallel network for east-west traffic cross clusters based on Node Resource Interface (NRI) to avoid intrusive modifications for clusters and limitations on CNI. A hybrid approach is provided for inter-cluster traffic: clusters can communicate through a hub cluster with public IP or connect directly if public IP is equipped. Moreover, cross-cluster service discovery follows the MCS standard to ensure seamless service access. All functionalities remain agnostic to Kubernetes and applications. A live demo will be shown in this session.

连接和服务发现通常是多集群管理的关键挑战，现有解决方案如Submariner引入了公共IP和特定CNI的先决条件。这对于像“东西计算资源转移项目”这样的项目是有问题的，因为集群缺乏公共IP并且由于不同所有权而具有不同的CNI。 本场演讲介绍了一种解决方案，基于节点资源接口（NRI）建立一个独立和统一的跨集群东西流量网络，以避免对集群进行侵入性修改和对CNI的限制。提供了一种混合方法用于集群间流量：集群可以通过具有公共IP的中心集群进行通信，或者如果具有公共IP则可以直接连接。此外，跨集群服务发现遵循MCS标准，以确保无缝的服务访问。所有功能都与Kubernetes和应用程序无关。 本场演讲将展示现场演示。
