【摘要】 针对高速网络海量数据采集、存储和管理问题,分析了传统IPFIX流量日志系统在高速网络中的性能问题,提出了基于IPFIX协议的用户网络流量日志系统体系结构的优化设计,改进了数据聚类和存储算法,包括二元归并方式采集数据以及多层结构的散列算法存储数据。经校园网部署应用证明,可提供万兆链路下用户网络日志详单及准确上网流量计量值。更多还原

【Abstract】 To deal with the large-scale traffic capture and management in high speed network, the performance of IPFIX system was studied. An optimized architecture was proposed and implemented based on improved binary information integration to collect data and improved multi-layer hash algorithm to storage data. This system was deployed in Tsinghua university campus network and can scale to the 10 GB network traffic collection and accurate pricing.更多还原
