Title: Simulator for the evaluation of distributed network-system performance
Abstract: The INSYDE simulator was developed as a tool for estimating the performance of large-scale, complex computer systems using graphical type figures to describe system operations. This paper provides an overview of an enhanced version of INSYDE that can be applied to distributed network systems. The model description method and a number of application examples are also presented. A major challenge in simulating distributed network systems that interconnect multiple computer systems over a network is how to describe the intricate, complex model conditions of computer systems including task processing and interrupts on the one hand, and network-related model conditions (e.g., [email protected] protocol, media access method, congestion control, broadcast communication, and so on) on the other in the most parsimonious fashion with the least amount of model description. In this work, the complex and intricate conditions of distributed network systems are simply described by creating a protocol media access method library, realizing packet splitting/merging and broadcast communication functions as nodes, adding system information that can be checked for congestion control, and multiplexing task processing.
