Title:
INFORMATION PROCESSING SYSTEM AND METHOD FOR CONTROLLING THE SAME
Document Type and Number:
WIPO Patent Application WO/2013/171802
Kind Code:
A1
Abstract:
An information processing system 1 includes a plurality of edge nodes 10 to provide services relating to files, and a core node 20 communicatively coupled to each of the edge nodes 10 and configured to send or receive data of the files to or from the edge nodes 10 and to manage the data of the files. Any one of the edge nodes 10 is granted a first right (RW) being an access right permitting update of the files, whereas any two or more of the edge nodes 10 are granted a second right (RO) that is an access right to prohibit update of the files. The core node 20 stores the access right granted to each of the edge nodes 10. When detecting that a failure has occurred in the edge node 10 granted the first right, the core node 20 sends one of the edge nodes 10 granted the second right a first instruction to take over the first right granted to the edge node 10 having the failure.
