Real-Time Performance Evaluation of Distributed Program Based on File Transmission Paths
Weizhong Qiang · Journal of Chinese Computer Systems · 2006
Based on the basic theory used for real-time distributed systems,a basic theory for evaluating real-time performance of distributed programs is deduced by combining with the character when distributed program executed.On the basis of these theories,we propose an approach to evaluation the real-time performance of distributed program.Our approach is based on three factors,which include the nodes on which program can be executed,the data files needed when program executes and the transmission paths of data file.The minimum of transmission time and the maximum of transmission time of each data file can be calculated out by using the three factors,and then the earliest response time and the latest response time of program can be gotten by deducing the transmission time of all data files needed when program executes.At the end of this paper,a case study is given to justify the validity of this approach.
