协议内容还原是进行网络内容安全监管的核心技术,而传统的协议还原系统采用单线程运行,还原效率较低,无法满足高速网络流量的需求.总结了协议还原的多核架构,针对协议内容还原的特点,提出了一种协议内容还原的通用算法模型,并给出了两种协议的具体还原示例.新的算法使用哈希散列链表来保存会话状态,提升了会话查找的速率,能够准确高效的完成协议内容还原.实验表明,算法在还原速率和还原准确率上具有优势. Restoration of protocol content is the core technology of network content security regulation, while the traditional protocol recovery system runs on a single thread, the restoration efficiency is low and can not meet the needs of high-speed network traffic.It summarizes the protocol-restored multi-core architecture, , This paper proposes a general algorithm model for reducing the content of protocol, and gives some concrete examples of the two protocols. The new algorithm uses hashed hash linked list to save the session state and improve the speed of session search, which can be accurate and efficient Of the completion of the agreement to restore the content.Experiments show that the algorithm has an advantage in the reduction rate and reduction accuracy.
