摘要
针对目前对高速网络数据监控、分析和性能预测的需求,对实时存取原始网络数据的软件解决方案进行了分析。以WinPcap为例,深入其内部运行机制,详细展示了网络数据包捕获中的各个阶段,并给出了每一阶段的详细性能评估,同时指出其中的性能缺陷和瓶颈所在,最后给出了改进各个阶段性能的详细解决方案,使其能明显改进高速网络数据包捕获速率,节省系统开销,为之后的数据包处理和分析留出充裕的资源。最后对改进方案进行了定量的分析和论证。
For the demand of monitoring and analyzing the high-speed network data and predicting the capability ,analyze the solution of the software for saving and reading the original network data .In this paper ,take WinPcap as example ,particularly prodict each stage of capturing network data with the inner running system ,provide the detailed performance evaluation , meanw hile find out the disadvantage of capability and choke point . T hen elicit the particular solution w hich improve the capability of each stage for improving the rate of capturing the packet obviously ,saving system cost and leaving abundant resource to process and analyze the pocket .In the end ,analyze and demonstrate the solution .
