According to the characteristic of high speed network , it also have realized the distribution of data handling with a linux cluster - lvs ; in final , the paper analysis the 3 layer of network data restore : ip layer , tcp layer and application layer . especially it made detailed analysis for application protocol restore . it also realized the data restore of simple high layer protocol 针对高速网信息流量大的特点，系统在一个linux集群- lvs上实现了数据包处理的分布性；最后，本文对网络数据还原的三个层面： ip层、 tcp层和应用层作了还原分析，特别对应用层的协议还原作了详细分析，并实现了其中简单高层协议的数据还原。
The gigascreen - ii , via its advanced flow processing design , implements multiple security functions in silicon including : policy searching , packet translation - which includes encryption , tunneling , authentication and network address translation - layer 2 and layer 3 packet processing , layer 4 flow processing , session table maintenance and deep packet inspection Ii处理芯片依靠它先进的流式处理设计，在硅片上执行多项安全功能：策略搜索，信息包翻译-包括加密，隧道通讯，认证和网络地址转换-第二三层的包处理，第四层的流处理，会话表维护和更深层的包侦测。
