【摘要】 当前SIP电话越来越流行,但是高可移植SIP终端的设计和实现却是一个难点。以设计和实现一个高可移植性的SIP终端为主要研究问题,首先介绍两个基础协议—SIP、RTP协议,然后从几个开源SIP协议栈和RTP协议栈中选取适合软件需求的协议栈,接着介绍软件的应用环境和软件的体系结构,最后,给出软件在Windows、Linux、uClinux、VxWorks上运行情况和相互通信的数据。通过实验数据,说明SIP终端的软件很好地满足了高可移植性的要求。更多还原

【Abstract】 Currently,communication based on SIP protocol is more and more popular.However,the design and implementation of high transplantable SIP terminal is a poser.Focusing on how to design and implement a high transplantable SIP terminal,in this paper it firstly introduces in brief SIP and RTP protocol,then after comparing some popular open source SIP stacks and RTP stacks,it chooses the protocol stacks from them suitable for the software.Afterwards it introduces the environment and the architecture of the software.Finally,the operation situation on Windows,Linux,uClinux,VxWorks and the communication data are provided in this paper.From the experimental data,we can see that the SIP terminal software proposed in the paper meets the requirement of high transplantation well.更多还原
