摘　　要：针对网络流量监测系统传输数据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,其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7个时,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。When data transmission speed of the network traffic monitoring system is too fast, the data packet loss, transmission stops, response error will occur. To resolve the problem, this paper proposed evaluation index for the sys- tem which uses the system throughput as core index to evaluate the system optimization performance throught the in- dex; selects the network protocol analysis system for multi-core optimization research, taking GTP-AS system as a spe- cific objective optimization,according to the system performance bottleneck, puts forward a set of multi-core platform optimization strategy. The experiment proves when number of the core processor computing core is increased to 7, a number of kernel optimization of network protocol analysis system throughput can reach 391. 73 ~ of the optimized pri- orty, effectively improves the performance of the system.
