Abstract
A multi-address space mobile network architecture is disclosed, in which edge networks (ENs) are connected to a core network (CN) through core edge routers (CERs). A distributed hash table (DHT) set in the CN is adapted to not only store or update a mapping relation between a CER ID and CER location information in the CN, but also receive registration information sent from a host through the CER, and store or update mapping relations between a host ID host identifier (HI) and the CER ID and between the HI and host location information. A method for registering host information includes the steps as follows. The host acquires routable host location information in an EN to which the host currently added and information of the CER in the EN. The host sends registration information to the CN through the CER in the EN. Further, a method for sending data is described. The network architecture and methods of the present invention may improve update and query efficiency of the registration information from the host.
