摘　　要：随着数据中心网络承载的数据量的爆炸式增长,越来越多的框架、模型和应用选择使用RDMA技术来加速网络传输。RoCE是RDMA技术在以太网上的实现,但针对RoCE网络目前还没有有效的状态感知和度量体系,无法全面展现RDMA网络状态。对此,提出针对RoCE的实时状态感知系统和多维度多层次的RDMA度量指标体系。采用旁路分布式流量捕获方式,运用Sketch算法全方位度量RDMA网络状态。系统易于部署且成本低,具有可扩展性和灵活性。实验结果表明,该系统能在较低误差下客观反映出RoCE网络状态,提供故障定位建议。With the explosive growth of data volume carried by data center network,more and more frameworks,models and applications choose to use RDMA technology to accelerate network transmission.RoCE is the implementation of RDMA technology in Ethernet,but there is few effective state awareness and measurement systems for RoCE network,which cannot fully show the state of RDMA network.In view of this situation,this paper proposes a real-time multi-dimensional and multi-level state awareness and measurement metric system for RoCE.It adopted the bypass distributed traffic capture method and used the sketch algorithm to measure the RDMA network state in all aspects.The system is easy to deploy and low cost,with high scalability and flexibility.The experimental results show that the system can objectively reflect the state of RoCE network with low error and provide fault location suggestions.
