摘要：提出一种新的基于端口地势值比较的数据转发新技术——Nature Flow。该技术不仅能有效确保二层数据无环路转发，而且能提升数据中心网络开放能力。新转发架构的价值在于构建大规模二层拓扑存环网络的无环转发能力、对应用程序开放网络端到端的距离感知能力、网络故障快速收敛和自愈能力、网络拥塞时的流量自主调优能力等。新转发架构有望变革现有技术，助力未来数据中心网络建设。

Abstract: A new data forwarding technology nature Flow based on the comparison of port terrain values is proposed, which can effectively ensure the no-loop forwarding of layer 2 data and improve the network opening ability of the data center. The value of the new forwarding architecture lies in the following aspects: the acyclic forwarding ability of large-scale two-layer network with topological rings, the end-to-end distance perception ability for the application in open network, the rapid convergence and self-healing ability of network failure, and self-tuning ability of traffic in network congestion. The new forwarding architecture is expected to change the existing technology and help the future data center network construction.
Keywords: Nature Flow; port terrain value comparison; no-loop forwarding; self-healing ability; end to end distance sensing; traffic self tuning
