The current studies focus on the data packet detection and filtering, without due consideration of the packet filter device deployment. If the packet filter is deployed properly, the network performance and efficiency can be significantly improved. Packet filters are always placed on the border of the administrative network, the boundaries between trusted and non-trusted networks. Generally, the packet filters are placed on the router in the border of the network, and a tremendous amount of time and space would be consumed, that results in time-delay and congestion, and hampers the efficiency of the network. In this paper, a new disposition algorithm is proposed. To compare various kinds of risks in the border and to remove the edge with operation risks, the packet filters can be placed in an efficient way by generating a shortest border, to provide a perfect protection for trusted networks between the internal network nodes. Experiment results show that the number of packet filters is reduced by 20% to 50%. The network delay time is reduced and the network connectivity is improved., authors=null, authorsList=null, authorCompany=null, correspAuthors=null, authorNote=null, correspAuthorsNote=Jie Wang,

articleAbstract=整合在路由器上的数据包过滤功能是网络安全的第一道防线，对保护网络的安全有着至关重要的作用。当前的研究主要侧重于对数据包的检测和过滤，忽略了数据包过滤器的部署问题，如果对其部署得当，能极大改善网络的性能和效率。在大规模的网络中，数据包过滤器被部署在管理网络的边界上，即信任网络和非信任网络之间。一般情况下，数据包过滤器被部署在网络边界的每一个路由器上，由于需要遍历路径上的过滤器，大量的时间和空间被消耗，容易造成时延、拥塞、丢包等问题，降低网络的效率。本文依据最短路径优先的思想，提出了一种新的部署算法，通过对比边界上各种风险，移除有操作风险的边界，产生一条最短虚拟路径，更加有效地部署过滤器的位置，给内部节点之间的信任网络提供保护，并使用基于风险的方法对虚拟边界进行离线计算。实验结果表明，使用该算法后，过滤器的数量减少20%～50%，网络的延迟时间变小，网络的连通性也得到改善。,
