摘　　要：针对栓通互联网上TCP通信比较慢等问题进行分析,对IPSec体系进行了剖析.为了提高IPSec保护的TCP数据的通信性能,提出采用ACK代理、数据Cache缓存以及IPSec over TCP等机制的TCAP(Tcp Cache Accelerate Protocol)协议,并给出了协议实现的结构和流程.为了对协议模型进行验证,文章以FreeSWAN软件为基础,对TCAP协议进行了设计和实现,提供了性能测试数据作为比较,并对新系统的性能进行了分析.This paper discusses the slow of TCP communication in WAN,and the architecture of IPSec is got.To improve the performance of TCP communication protected by IPSec in WAN,the new TCAP（TCP Cache Accelerate Protocol）is exposed including its structure and procedure.The soft structure of FreeSWAN is improved and the performance test data are presented in order to validate this new protocol.Finally,the performance of the new system is analysed detailedly.
