摘要
下一代网络是以IP技术为核心,同时支持语音、数据、多媒体业务的新型网络。会话初始化协议SIP是一种在IP网络中建立、修改和终止多媒体会话的应用层协议。而主机标识符协议HIP的优势主要体现在提供安全和移动性支持。将SIP协议和HIP协议结合起来实现网络语音业务,设计了一种基于HIP的SIP电话协议流程,在支持HIP协议的主机上实现SIP电话,同时提供端到端的安全数据传输和网络层移动性支持。
Next generation network is converged at IP centric networks that simultaneously support voice, data and multimedia services. Session Initiation Protocol （SIP） is an application layer control protocol that can establish, modify, and terminate multimedia sessions （conferences）, especially in Voice over IP. Host Identity Protocol （HIP） is an experimental protocol which aims to handle the IP mobility and secURLty using a different approach. In this paper, a new scheme based on Host Identity Protocol （HIP） and SIP is proposed, which can implement Internet telephony calls. And the specific protocol flow of HIP based on SIP soft phone is designed. It can implement SIP soft phone communication between hosts which is supporting HIP. The proposed architecture ensures security of end to end data transmission and provides mobility support in the network layer.
