针对当前基于软/硬件的流导出技术存在的数据失真、不易扩展等问题，本文提出一种准确、通用、易扩展的高速网络流量处理框架NTCI Flow。首先,基于PF_RING DNA实现了高性能的网络包抓取，采用基于网络包五元组的负载均衡策略对网络包进行分组分发，并利用批处理、无锁队列、多线程等技术将多个网络包封装为单条大消息并行发送，改进与优化网络包转发性能；然后,采用Kafka消息系统作为中间件接收并缓存网...
Counter Braids: A Novel Counter Architecture for Per-Flow Measurement
Statistics Counters Network Measurement Message Pass- ing Algorithms
2015/8/21
Fine-grained network measurement requires routers and switches to update large arrays of counters at very high link speed (e.g. 40 Gbps). A naive algorithm needs an infeasible amount of SRAM to store ...
Adaptive modulation with smoothed flow utility
A wireless connection data flow trade smooth data traffic application
2015/8/7
We consider the problem of choosing the data flow rate on a wireless link with randomly varying channel gain, to optimally trade off average transmit power and the average utility of the smoothed data...
