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.
In order to improve the communication performance of IPSec-protected TCP data, this paper analyzes the problems such as the slow TCP communication over the Internet and the analysis of IPSec system.In order to improve the communication performance of IPSec-protected TCP data, this paper proposes TCAP (Tcp) mechanism using ACK proxy, data cache and IPSec over TCP mechanism, Cache Accelerate Protocol) and gives the structure and flow of protocol implementation.In order to verify the protocol model, this paper designs and realizes the TCAP protocol based on FreeSWAN software and provides performance test data for comparison The performance of the new system was analyzed.
