ROUTING CONSTRUCTING METHOD AND APPARATUS

摘要

The provided is a routing constructing method, which comprises: the node searching the destination node in the first grade node group according to the first grade routing information, and if finding the destination node, then returning the search result or the data saved in the destination node, or if else, executing the following steps: the node searching the destination node in the higher grade node group according to the higher grade routing information, and if finding the destination node, then returning the search result or the data saved in the destination node, or if else, continuously executing this step. Embodiments of the present invention also provides a node ID constructing method, an apparatus for constructing node ID with geography location identifier, a method for constructing a two-hierarchies DHT network, a communication apparatus, a communication network system and a communication network. With such a hierarchical communication system, most traffic produced in the daily service operation of the communication network can be limited in a small region, and it is avoided to occupy too much of the bone network bandwidth, which is not very redundant.
