摘要
本文首先针对广域网上TCP通信比较慢等问题进行了分析,接着再对IPSec体系进行剖析。为了提高IPSec保护的TCP数据的广域网通信性能,本文提出了采用ACK代理、组包和压缩以及IPSecover TCP等机制的TTAP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,本文以FreeSWAN软件为基础,对TTAP协议进行了设计和实现,并提供了性能测试数据作为比较,最后对新系统的性能进行了分析。
This paper discusses the slow speed of the TCP communication in WANs，and analyses the architecture of IPSec. To improve the performance of the TCP communication protected by IPSec in WANs, a new TTAP（TCP Tunnel Acceleration Protocol）is proposed 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.
