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。
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 implementations on different layers are discussed and the security of this new solution is analyzed.
