چکیده

Recently large scale distributed workstation LAN systems have been widely used in educational systems like educational centers in universities. In those systems, avoiding the large traffic caused by many users’ continuous operations is one of the most important problems. In this paper we modeled the users’ behavior in educational systems, and simulated and analyzed the traffic of the Ethernet LAN under such access concentration. Six variations of Ethernet LAN including traditional CSMA/CD Ethernet and switching Ethernet, TCP/IP and NFS are simulated. From the results of the simulation, we obtained the proper design for educational workstation LAN systems considering cost.

A Modeling and Simulation Method for Transient TraÆc LAN

In this paper a protocol-based modeling and simulation method of performance evaluation for heavy traÆc and transient LAN is proposed. In the method a node on a LAN is modeled as a set of detailed communication protocol models. By parallel and event driven processing of the models, high accuracy and high time-resolution of evaluation of LAN behaviors can be obtained at multi-layer protocols. Th...

Performance Evaluation of a Client-Server System on High-Loaded LAN

In this paper we evaluated a performance of a client-server system on a hi-loaded LAN with behaviors of user applications. We selected an educational client-server system as a sample of such systems. This simulation was performed by an event-driven simulation model that have detailed models of multi-layer protocols (Ethernet, TCP/IP, NFS and FTP). We evaluated the Ethernet states under the use ...

Performance evaluation of the croissant production line with reparable machines

In this study, the analytical probability models for an automated serial production system, bufferless that consists of n-machines in series with common transfer mechanism and control system was developed. Both time to failure and time to repair a failure are assumed to follow exponential distribution. Applying those models, the effect of system parameters on system performance in actu...

A new architecture for efficient parallel computing in workstation clusters: conceptions and experiences

The acceptance of parallel computing in workstation clusters has increased in the past years. One important reason for this is the cost-efficiency of workstation clusters as an alternative to specialized distributed-memory parallel computer systems. A potential bottleneck for distributedmemory architectures is the interconnection network between the processing elements. This is the main disadva...
