Analysis of Self-Adapted Fault-Tolerant System in Distributed Information Resource Management
Xi Ai Yan, Jin Yang · Advanced materials research · 2011
Distributed information resources may fail at any time, thus redundancy can be used to enhance fault tolerant capabilities as a technology. In connection with distributed information resource management, the paper has designed a self-adapted fault-tolerant system taking advantages of redundancy technology. In order to reducing overhead, the system makes use of copy-on-write strategy to find checkpoints and chooses the best checkpoint interval for execution efficiency improvement. The experiment indicates that redundancy system has got good results in application with adaptive, simple, efficient and reliable features.
