摘　　要：随着互联网应用的全球化发展,随之而来的网络信息安全等问题却影响了用户对互联网络服务安全性和可靠性的信任与使用。防火墙技术是目前应对网络安全问题的重要安全技术,在介绍防火墙技术分类的基础上,研究了AFBV算法的主要思想。针对该算法在数目较大的多维规则库下可能出现时间性能消耗过大的问题,进行了优化和改进,有效地克服了AFBV算法在复杂网络环境中的缺陷,并通过仿真实验给出了对比的实验结果。Along with the globalisation of Internet application,the attendant problems of the security of network information and so on have however affected the users on their trust of the safety and reliability of Internet services and their use of it.At present the firewall technology is the important security means in dealing with the problem of network security,on the basis of the introduction of firewall technology classification,in this paper we have studied the main idea of the AFBV algorithm.To solve the problem of this algorithm that in multidimensional rule library with large number it might appear the problem of time performance excessive consumption,we make the optimisation and the improvement,the deficiency of the AFBV algorithm in complex network environment has been overcome effectively.The contrast experimental result has been given through simulation experiment as well.
