摘要:
 为了测量数据中心网络的单向时延,针对数据中心网络高带宽低延迟的特点,提出了分布式有损差分聚合( Dis-tributed Lossy Difference Aggregator,D-LDA)测量方法。该方法在有损差分聚合算法的基础上,能够测量网络中任意端到端的单向时延,并且增强了对大数据量报文的处理能力,且架构灵活,扩展性好。开发了实际的测量系统进行实验,系统采用FourInOne分布式框架和基于Java的B/S架构。测试结果显示该方法计算效率高,CPU占用率低,占用带宽小,可以广泛地用于数据中心网络进行性能监测。
Abstract:
 In order to measure the one-way delay of the data center network,a measurement method called Distributed Lossy Difference Aggregator ( D-LDA) is put forward,which is adapted for its characteristic of high bandwidth and low latency. Based on a lossy differ-ence aggregator,this method can measure latency of any point to point in network and has a more powerful ability to deal with big data packets,with flexible software architecture and high scalability. A practical software measurement system is developed to experiment, which is based on FourInOne distributed framework and B/S architecture based on Java. The results show that this way has a high compu-ting efficiency,a low CPU and bandwidth utilization. It can be used to monitor performance in data center network extensively.
