英文摘要： The research on the future IP-based Aeronautical Telecommunications Network (ATN/IP) is an important part for the aviation industry. NEMO(Network Mobility) is one of the key technologies which can handle the mobility management of the whole network. The existing protocols regarding NEMO can not satisfy the demands of aeronautical environments. The aviation industry is currently at the beginning of the research on the NEMO. The work on NEMO can support China's Big Plane project. An aircraft generally contains many computing nodes, sensors, and other devices that are possible to address individually with IPv6. Given that a craft has only a small number of access links, we can use NEMO route optimization (RO) to manage the large onboard network's reachability over the few dynamic access links. The goal of the research is to contribute Moving Networks Integration to the design of ATN/IP. The main research points are as follows: 1. Traffic separability. It should be possible to apply RO only to flows that really require it. So we should differentiate the traffic of the services. 2. NEMO Route Optimization. The NEMO will avoid some suboptimal routing present when a network moves, by both optimizing flows between nodes within the NEMO and external CN, and also by optimizing the routing in nested mobile networks. 3.
