摘要
分析了三种防火墙技术,然后在OPNET仿真平台中构建仿真场景及模型,两种不同的场景对网络性能产生了不同的影响,通过比较两种情况下经过量化的网络性能指标变化曲线,可以得出结论:网络所需的安全程度和数据操作速度之间存在着一个权衡。
Based on the analysis of three firewall technologies,this paper has constructed the emulative scene and model on the platform of OPNET emulative,From the finding that different scene has different effect on the network performance,and through the comparative studies of variation curves obtained by quantifying the network performance index,the authors reach the conclusion that there must be a balance between the degree of safety which the network needs and the data operating speed.
