摘　　要：针对网络流量监测系统传输数据量速度过快时,存在的数据丢包、传输停止、响应错误等性能问题,提出了一套针对网络流量监测系统的评价指标,将系统的吞吐量作为核心指标,通过评价指标来对系统的优化性能进行评估;选取了网络协议解析类系统进行多核优化研究,以GTP-AS系统作为具体目标进行优化之后,根据系统的性能瓶颈提出了一套多核平台优化策略,并且通过实验证明,当核心处理器的计算核心数量增加到七个时,完成多核优化的网络协议解析系统的吞吐量能够达到优化之前的391.73%,有效提高了系统性能。As for the data packet loss ,transmission suspence ,response error when the network traffic monitoring sys‐tem data transmission is too fast ,a set of evaluation index for network traffic monitoring is proposed ,which takes system’s throughput as core index ,and evaluation index is used to evaluat the optimization performance of the system .The network protocol analysis system is selected to make multi‐core optimization research .After optimization of GTP‐AS as the specific objective ,a set of multi‐core plafform optimization strategy is proposed based on the system’s performance bottleneck .Ex‐periments demonstrate that throughput of network protocol analysis system through multi‐core optimization can be 391 .73%of that before optimization when the number of kernel processor adds to seven ,effectively improving the system perform‐ance .
