Abstract
The present invention discloses a name-to-address mapping system in a locator and identifier separation network. The system includes mapping nodes and access service nodes connected to each other through the network. The mapping node includes a transceiver module, a first storing module, a node determining module, a second storing module, and an address inquiring module. The present invention also discloses the corresponding method. In the present invention, the one-hop Distributed Hash Table (DHT) algorithm is used to generate a node routing table and a local mapping table whose performances are greatly improved when compared with the Content Addressable Network (CAN) algorithm, thus the phenomenon of the non-uniform distribution of mapping relations in mapping nodes caused by the operators assigning identities section-by-section can be avoided.
