Modeling and analyzing distributed computing environment with Petri nets. Case study: Windows NT*Domain based environment

Microsoft´s Windows NT based systems are replacing the role of lower and middle range UNIX based systems in various fields. There have been many studies on the modeling and analysis of Unix based distributed computing environment for the resource allocation problem. Although, the basic principles may be similar to those of Windows NT based environment, the whole scheme is somewhat different from the traditional approaches. Extensive experiments are conducted varying the number of servers in a domain from one to ten, changing the number of clients from one to two hundred, processing number of transactions and transferring big chunks of data. The authors proposed a simple time Petri net model for the Windows NT client server environment based on the experiment results. The simple analysis can be done with this model, otherwise impossible
