随着互联网的不断发展,涌现出一些具有优异特性的协议栈,例如流控制传输协议、数据报拥塞控制协议.现有的应用程序并不能兼容这些新的协议栈,因此难以享受到新协议带来的好处.文中提出一种设计,在不修改应用程序的情况下使其基于新的协议栈进行通信,从而使现有应用能够方便地享受到新协议的特性,并为新旧网络协议栈的过渡带来便利.采用SCTP协议作为蓝本,设计并实现了一种TCP到SCTP的转换模块,使现有基于TCP的应用程序能够使用SCTP进行通信,最后采用WEB浏览器这一应用程序对协议转换模块的功能进行验证,实验结果证明了协议转换模块的可行性.%With the continuous development of the internet.it is a fact that there are some new internet protocol stack with excellent features , such as stream control transmission protocol .datagram congestion control protocol. Legacy applications are not compatible with the new protocol stack, making it difficult to enjoy the benefits of the new advantages. It presents a design,which without modifying the application itself,makes legacy applications communicate based on the new protocol,and easily enjoys the characteristics of the new features. This will bring the convenience of the transition of old and new network protocol stack. Take SCTP as the blueprint, design and implement a conversion module of TCP to SCTP, making the leagcy applications to call SCTP instead of TCP. In the end use WEB browser to test the functions of the protocol conversion module. The results prove the feasibility of protocol conversion module.
