【摘要】 NAT穿越技术是基于分组的多媒体传输技术中一个重要的研究课题。目前已有不少切实可行的解决方案,但它们都具有一定的局限性。主机标识协议(host identity protocol,HIP)在传输层与网络层之间引入了新的协议层,打破了身份标识与拓扑位置的绑定。通过引入HIP,提出一种基于HIP的NAT穿越方案。讨论了网络体系中各层的具体穿越办法,并对新方案进行了安全性分析。更多还原

【Abstract】 Network address translator(NAT) traversal solution is an important research project in packet-based transportation technology of multimedia.At present,there are many feasible solutions,but they all have respective defect in different topology environment.The host identity protocol(HIP) introduces a new protocol layer between the transport and network layers,breaking the fixed binding between host identities and locations.By introducing HIP,a HIP-based solution is proposed for NAT traversal.At the same time,relevant im-plementations on different layers are discussed and the security of this new solution is analyzed.更多还原
