Distributed storage system, connection information notifying method, and recording medium in which distributed storage program is recorded

A connection information notifying method of a distributed storage system, the distributed storage system including a plurality of node apparatuses connected to a plurality of different networks through a high order apparatus group or a low order apparatus group, the high order apparatus group including at least one communication apparatus which connects between the networks, the low order apparatus group including at least one communication apparatus which is located below the high order apparatus group in the order level and is connectable to the plurality of different networks through the high order apparatus group, the connection information notifying method comprising:

• acquiring first connection information indicating a high order apparatus group or a low order apparatus group, which is a connection destination of a node apparatus, from a first node apparatus, which includes a first storage unit that stores connection relationship information on a plurality of high order apparatus groups and a plurality of low order apparatus groups connected through networks, based on location information indicating locations of a plurality of node apparatuses in the distributed storage system that stores a plurality of contents so as to be distributed in the plurality of the node apparatuses and the connection relationship information stored in the first storage unit;
• and
• transmitting the first connection information acquired in a step of the acquiring to any of the plurality of node apparatuses included in the distributed storage system.

A recording medium which records a program causing a computer to perform:

• an acquisition unit and a transmission unit in a distributed storage system that includes a plurality of node apparatuses connected to a plurality of different networks through a high order apparatus group or a low order apparatus group, the high order apparatus group including at least one communication apparatus which connects between the networks, the low order apparatus group including at least one communication apparatus which is located below the high order apparatus group in the order level and is connectable to the plurality of different networks through the high order apparatus group,
• wherein
• the acquisition unit acquires first connection information indicating a high order apparatus group or a low order apparatus group, which is a connection destination of a node apparatus, from a first node apparatus, which includes a first storage unit that stores connection relationship information on a plurality of high order apparatus groups and a plurality of low order apparatus groups connected through networks, based on location information indicating locations of a plurality of node apparatuses in the distributed storage system that stores a plurality of contents so as to be distributed in the plurality of the node apparatuses and the connection relationship information stored in the first storage unit;
• and
• the transmission unit transmits the first connection information acquired by the acquisition unit to any of the plurality of node apparatuses included in the distributed storage system.
