Recent years, with the continuous expansion of Internet-scale, as well as terminal enhancement of the ability to move, the Internet essentially does not support mobility and routing scalability problem gradually highlights. In order to solve the above problems have been proposed location and identity separation (ID and Locator Separation) ideas, there are already a variety of solution based on the location and identity separation. Network architecture based on the location and identification of separation, due to the existence of a single point of failure and communication bottleneck for Internet mobility management mechanism, is no longer applicable. Although mobility management solutions based on the location and identification of separate solutions, but these mobility management solutions to the following problems: First, the actual deployment is difficult, and second, there are security risks Third, packaging and new The introduction of options to reduce the bandwidth utilization. Therefore, a need to propose a novel separation of location and identity-based mobility management solutions. Firstly leads summarizes the existing problems of the Internet as well as the cause of these problems based on fundamentally solving the above problems have been proposed - the location and identity separation, the introduction of the analysis location and identity separation technology for mobility management zone to. Then an overview of mobility management technology and its research status, through the analysis of existing mobility management solutions exist, summarizes the design of mobility management solutions based on the location and identification of separation should have characteristics. On this basis, the paper for the existing problems of the existing mobility management solutions based on the location and identity separation, the proposed network architecture based on the location and identity separation, design the corresponding position, identifiers, and mapping system, and based on that architecture design is based on the destination address rewrite the mobility management solution (Mobility Management based on the ID and Locator Separation - MILS), including the registration process, the the domain location updating and the switching control process, inter-domain location updating and the switching control process. According to the design described above, there is described a data transfer process, including the data transfer process when the communication between the extended terminal and extended the data transfer process between the terminal and the traditional terminal summarizes the destination address, and on this basis rewrite bring advantages. Finally, the method of mathematical modeling, signaling overhead, switching delay, etc. analyze the performance of the mobility management solutions. The results showed that the mobility management solutions can provide lower signaling overhead and lower switching delay, and can reduce the transmission of data packets overhead.
