Abstract
The embodiments of the present invention disclose a system for data communications, a router, and a method for data transmission and mobility management. The method for data transmission includes: receiving, by a first AR, data; identifying the transmission route based on the results of querying the local mapping information base; and transmitting data, where the local mapping information base stores the mappings between IDs and LLs. The embodiments of the present invention completely separate the ID, LL, and GL of the terminal, and thus solve the problems with the routing table expansion and scalability faced by the Internet. In this way, the terminal data can be transmitted without changing the terminal or the routing protocol stack; in addition, the hierarchical mapping helps reduces the amount of locally and globally stored information, and thus accelerating the query.
