Abstract

The invention discloses an addressing system and method aimed at layering host marking and based on overlaying DHT; structure of each addressing server in the system is identical and is provided with a node accessing and exiting processing module, an information maintenance module, a route searching module, a mapping record information memory module, and an overlaying DHT structure establishing and maintenance module. The addressing method is to set up the overlaying DHT first: non-semantic host identifiers used in the network are hierarchically transformed; area marks indicating the locating area position of each node are added; then each node is divided into different areas, and each area DHT is set up respectively; finally, all the area DHT are overlaid together to constitute a global DHT; when routes are looked for and transmitted, a next hop is chosen in priority in the area DHT based on the overlaying DHT; trans-regional routing times should be reduced to the fully extent to improve routing efficiency; each operation of registration / updating is carried out in two DHT simultaneously to realize equity of load on balance and economy.

Description

technical field

[0001] The present invention relates to an addressing system and an addressing method in an IP network, specifically, an addressing system and an addressing method based on a superimposed DHT (Distributed Hash Table) for hierarchical host identification. The present invention can aim at the current network architecture where identity and location are separated, and provide registration and analysis services for each host in the IP network from identity identification to location identification mapping information, and has high registration and analysis efficiency and good load balance and fairness, which relieves the excessive dependence of the addressing of the original network architecture on the DNS system. It belongs to the field of Internet technology. Background technique

[0002] In the current Internet architecture, the IP address has dual semantics and plays two roles: it not only describes the location information of nodes in the network, and is us...
