Store-and-Forward Computer Communications Over Noisy Channels.

摘要

A model is developed for a computer communications processor with large storage capacity. The model follows single message positive acknowledgment protocol wherein the transmitting node acquires messages from the external environment, transmits them to the receiver, and awaits acknowledgment. Special attention is given to modeling the effects of transmission errors, either in the message or the acknowledgment, upon the service time of the computer communications network. These effects of error have generally been ignored in previous investigations. In order to realistically account for the service time distributions found in actual computing systems, which have bounded domains, an analysis of M/G/1 queueing servers with service times of this sort was necessary. This analysis (Appendix) focuses upon servers with uniform service times, and those whose service time distributions can be approximated by a section of a normal distribution. (Author)
