Distributed network construction and storage method, apparatus and system

A distributed data storage apparatus, comprising:

• an obtaining module, adapted to obtain geographic location information about data, and determine the storage area of the data according to the geographic location information about the data;
• a Hash module, adapted to calculate the key value of the data;
• and
• a storage module, adapted to select a local node in the storage area determined by the obtaining module according to the key value, wherein the key value is calculated by the Hash module, and store the data into the local node.

A distributed network construction method, comprising:

• obtaining geographic location information about a node;
• determining the home area of the node according to the geographic location information about the node, and determining the ID space of the node according to the home area of the node, wherein different areas correspond to different ID spaces;
• and
• selecting a value in the determined ID space to construct the ID of the node.
