<p>By dividing domain mapping planes and adding a domain mapping server, the system and method of the present invention thereby can enable querying the relationships from the cross-domain identifier to the domain mapping plane by the domain mapping server, obtaining the entrance address of the destination domain mapping plane, and then transmitting cross-domain packets to the destination domain mapping plane to complete the communication finally. In the domain mapping plane, applying one-hop Distributed Hash Table (DHT) technology to constitute a high capability distributed database for storing name (viz. identifier) and address (viz. routing ID) mapping relationship, thereby in the domain mapping plane the quick query of mapping relationships completed in one hop can be enabled, and the routing efficiency is improved. When multiple operator domains deploy a network, domain mapping planes are divided according to the operators, namely each operator constitutes an independent domain mapping plane, and a unified domain mapping server is set, so high capability locator and identifier mapping planes applicable to multiple operators deployment network can be provided.</p> |
