Eidolon: Real-time performance evaluation approach for distributed programs based on capacity of communication links

Abstract

In this paper, we propose an approach for the real-time performance analysis of distributed programs, called Eidolon. The approach is based on the capacity of communication links. In Eidolon, some algorithms are designed to find all the transmission paths of each data file needed while the program executes, count the transmission time for each the transmission path, then get the minimum and the maximum transmission time by analyzing all the transmission paths of each data file, and at last, calculate the fastest and the slowest response time of distributed programs. A case study is given at the end of this paper to justify the validity of this approach. © Springer-Verlag 2001.
