ofdistributed
1.Itis believed that DRD technology is a natural and interesting combination and development ofdistributed computing and RAID technologies.
2.With the development of network distributed computing, the characteristics ofdistributed applications bring many challenges to the software architecture anddeveloping methods.
3.Secondly, we analyze the excellence and shortcomings of the main distributed technique (CORBA, DCOM, Java, Web Service) and propose the characteristics ofdistributed technique abreast of the times.
4.Based on the apply mode ofdistributed file system, we did some clustering analysis for the factors which will influence the highavailability issue. Based on the failure and restoring factors, we defined the high availability indistributed file system, and constructed a qualitative analytical model for high availability issue indistributed file system—DFS_HAL ( Distributed File System High Availability Level ) model.
