A convergence algorithm for enhancing the performance of distributed applications running on sizeable networks

The proposed convergence algorithm is aimed at enhancing the performance of distributed applications running on sizeable networks exemplified by the I nternet. The aim is achieved by quickly and accurately predicting the mean message response time of a communication channel with only end-to-end consi deration. With the predicted mean the correct window size of the desired co verage of time-out tolerance for message transmission and response can be c omputed. The correct window size contributes to reduce excessive message re transmissions caused by time-outs. The proposed algorithm is particularly u seful in helping time-critical distributed applications deliver their corre ct functions because prolonged delays in message response in these applicat ions can lead to fatal errors. The discussion in this paper is focused main ly on the development of the convergence algorithm. Results from experiment s have concluded that the proposed algorithm is indeed an effective solutio n for the stated aim. The simplicity of the algorithm is an advantage becau se it makes its implementation in real systems easy.
