摘要
一体化网络采用身份与位置分离映射机制,避免了传统网络中IP地址在语义上的双重属性问题,使得一体化网络不但可以有效解决核心网的路由可扩展问题,而且可以很好地支持节点的移动性。提出了一种一体化网络的移动性管理机制,详细描述了移动过程中该机制的协议流程,然后建立了一个移动过程信令开销分析模型,并给出了通过该模型计算最佳域大小的方法。根据建立的信令开销模型得出的各种信令开销,通过仿真得到了移动过程中不同参数对总信令开销的影响。
The universal network can not only resolve effectively the routing scalability problem of the core network, but also support very well the node mobility, adopting separation and mapping scheme of the identifier and locator, which avoids the problem of the overloaded semantics of IP addresses in the traditional network. Propose a type of mobility management mechanism of the universal network, describe in detail the protocol flow during the mobile process, establish the analysis model for signaling overhead during the mobile process and provide the method for the calculation of the best domain value by this model. Based on the established model for signaling overhead obtain various signaling overheads and get the influence on signaling overhead of different parameters during the mobile process through the simulation.
