智算中心组网技术及应用

摘要：智算中心网络架构正面临高性能、低延迟、高扩展性和可靠性的挑战。当前多种主流的智算中心组网拓扑结构各具优缺点。针对智算中心各种组网方案，边界网关协议（BGP）、开放式最短路径优先（OSPF）、中间系统到中间系统（IS-IS）、胖树路由协议（RIFT）等具有不同适用性。中兴通讯对智算中心组网和部署方案进行实践，提出Scale-Up与Scale-Out网络融合的创新方案，并通过协议优化提升等价多路径路由（ECMP）路径选择精度与故障收敛效率。这些研究和实践可为智算中心网络设计提供参考，推动智算中心技术的发展和应用。

Abstract: The network architecture of intelligent computing centers is facing challenges in terms of high performance, low latency, scalability, and reliability. Currently, there are several mainstream networking topologies for intelligent computing centers, each with its own advantages and disadvantages. Meanwhile, for various networking solutions in intelligent computing centers, protocols such as BGP, OSPF/IS-IS, and RIFT have different applicabilities. ZTE Corporatiuon has implemented practical practices in the network architecture and deployment solutions for intelligent computing centers, proposing an innovative converged solution integrating Scale-Up and Scale-Up networks. By employing protocol optimizations, the precision of ECMP path selection and the efficiency of fault convergence have been significantly enhanced. These studies and practices can provide references for the network design of intelligent computing centers and promote the development and application of intelligent computing center technologies.
