Abstract: Based on the analysis of packet filtering techniques and current optimization algorithms, this paper proposes a new filtering-rule structure model and an adaptive optimization strategy that aims to enhance the performance for packet filtering firewalls. A series of trails on performance evaluation prove the effectiveness and usability of the special strategy.

Key words: packet filtering, dynamic statistics, adaptive optimization

摘要： 针对影响防火墙性能和自适应能力的因素，以封包过滤技术和现有自适应策略为基础，通过研究过滤规则组成和封包过滤匹配过程，提出新的过滤规则参照模型和更通用的自适应算法。通过一系列具体试验对策略进行性能评估的结果，证明该自适应优化策略的有效性和可用性。
